Presenting the MINI Roadster Concept, the brand once again sets a new trend for individual mobility. This is where a purist character, elegant design and fascinating driving qualities come together in the vision of an open two-seater meeting the demands of a modern and self-confident target group. Individual style, premium quality and exactly the right balance of driving pleasure and efficiency in our modern day and age give the MINI Roadster Concept its very special character, the design of the car clearly reflecting this focus on maximum driving pleasure with nothing but the sky above.

Spontaneous pleasure – the domain of the MINI Roadster Concept.

The MINI Roadster Concept offers ideal conditions for an emotional experience also on short trips, at the same time urging the connoisseur and aficionado to escape the usual congestion of city traffic.

With its intentional restriction to two seats and lightweight construction, the car from the start expresses its focus on uncompromising agility. Its stylish looks and high-class interior ambience, in turn, give this very special two-seater truly exclusive character.

Exterior design: unique proportions, expression typical of MINI.

The body design of the MINI Roadster Concept visualises the identity of the brand and its innovative power in a truly fascinating combination. The integrating factor throughout is the design language so typical of MINI, determining both the elements characteristic of the brand and the car’s innovative features. In its design the MINI Roadster Concept is refreshingly different, but nevertheless absolutely harmonious and perfectly balanced in its look so reminiscent of MINI. In a truly incomparable manner, therefore, the MINI design of this concept car offers an extroverted look in style and with genuine class.

This new two-seater measures 3,714 millimetres/146.2" in length and 1,683 millimetres/66.3" in width. The height of the car is 1,356 millimetres/53.4".

Again in typical MINI style, the MINI Roadster Concept comes with extra-short body overhangs front and rear emphasising the athletic stature of the car and alluding even at a standstill to the unique handling of the MINI Roadster Concept characterised by thrilling agility and that typical feeling of go-kart motoring. The front section including the large headlights and the hexagon radiator grille is the same as on the MINI Cooper S up to the A-pillars. The entire front air dam, in turn, has been adjusted to the sporting look of the car and appears to be even wider and more striking than before. The inner area within the chrome radiator grille comes with louvers in body colour, while the bonnet stripes extending all the way into the radiator grille add a sporting touch and provide clear optical differentiation on the MINI Roadster Concept.

The low, short and dynamically raked A-pillars merge gently into the roofline of the car as long as the roof is closed. The glazed area in the passenger cell is significantly lower, slimmer and even more dynamic than on the regular production models, providing a strikingly sleek silhouette for an even more sporting and performance-oriented look.

The typical roadster character of the concept car comes out clearly when both open and closed, the waistline rising up slightly towards the rear in a linear perspective also maintained with the roof open.

The pure and open character of the car is of course most obvious and appealing with the roof down. Folding down in a compact configuration, the roof leads on to a short luggage compartment lid housing the luggage compartment separated from the passenger compartment.

The passenger compartment limited to two seats is covered – whenever required on account of wind and weather – by a high-quality soft top with the smallest possible dimensions.

With the roof closed, on the other hand, the MINI Roadster stands out clearly from the MINI Convertible through its notchback contour. The soft top opens and closes manually in a process performed very quickly and with utmost ease thanks to the compact dimensions of the roof.

Innovations in typical MINI style: rear-end design, luggage compartment and safety concept.

The rear view of the car is characterised by innovative design features clearly originating from the design language so typical of MINI. The side panels, the rear apron and the luggage compartment lid flow together to form a harmoniously configured sculpture not only boasting that cascading style so typical of the brand, but also taking up elements of the front-end design re-interpreted here in a new and unique manner.

Increasing in width step-by-step from top to bottom, the rear structure of the car gives the MINI Roadster Concept a particularly powerful stance on the road also from this perspective.

Beneath the short rear end of this compact car so typical of a roadster in its style, the MINI Roadster Concept offers a luggage compartment unusually large and generous for a vehicle in this segment. And since the soft top of the MINI Roadster Concept moves down directly behind the seats, luggage capacity remains exactly the same with the roof both open and closed.

Another feature of modern function quite unique in a compact roadster is the through-loading from the luggage compartment to the passenger compartment, with the bulkhead featuring a lockable opening between the two sections.

The rollbar instantaneously moving up whenever required and featured for the first time on the MINI Convertible is an important highlight of the safety concept ensured from the start in developing this unique car. The single-piece aluminium bar covering the entire width of the interior and moving up whenever required under electromechanical power within 150 milliseconds interacts with the reinforced windscreen frame as an essential element of maximum occupant safety on the passenger cell.

The outstanding character of this two-seater comes out not only in the harmonious design of the exterior so typical of the brand, but also in the interior with its high quality of finish and outstanding elegance. Exclusive style and a supreme touch of quality are also borne out by the colour scheme and the choice of materials, high-class wooden trim and selected colour highlights on the door linings and seat upholstery providing a highly attractive contrast to the interior as a whole finished in discreet black.

As yet a further feature the cockpit of the MINI Roadster Concept comes with a multi-functional display able to provide a range of information according to the user’s individual choice. Positioned to the left of the rev counter, this display serves, for example, to show the driver exactly how much time he has spent on the road with the roof down, like with the Always Open Timer on the MINI Convertible, and is also able to provide further display functions typical of MINI.

McLaren MP4-12C

A long held dream

The McLaren MP4-12C is the first in a range of high performance sports cars from McLaren Automotive, the independent car division based at the McLaren Technology Centre in Woking, England.

The 12C, and future models within the range, will challenge the world’s best sports cars benefiting from the expertise and virtuosity of the McLaren Group.

Twenty years of sports car design, engineering and production combined with inspirational success in Formula 1 have driven Ron Dennis, McLaren Automotive Chairman, to announce his plans for the ultimate line-up of technology-led and customer-focused performance cars for the 21^st century. The rules in the sports car world are about to be re-written.

Through a rich modern history, McLaren’s automotive division has already built the world’s most critically acclaimed supercar, the McLaren F1 (1993-1998) and the world’s best-selling luxury supercar, the Mercedes-Benz SLR McLaren (2003-2009). McLaren Automotive now looks to the future with a new range of revolutionary sports cars.

“It is a long-held dream of mine to launch high performance sports cars that set new standards in the industry,” said Dennis.

“We began designing and building cars for aficionados of thoroughbred sports cars almost 20 years ago. Incorporating the leading edge technologies that the McLaren Group has built up, I believe we are now perfectly placed to open up this new chapter in McLaren’s history,” he said.

The MP4-12C is pure McLaren, featuring no carryover parts from any other car, and will be produced by McLaren in the UK. It goes on sale through a dedicated, worldwide retailer network in early 2011.

Ultimate car for the core market

The McLaren MP4-12C is a high performance two-seat mid-engine model in the ‘core’ sports car market sector for cars costing between £125,000 and £175,000.

“Worldwide demand for high performance cars is strong, in large part because of great cars from great competitors. With McLaren joining that list, it will grow stronger still. What we are offering is a new approach to the market,” said Ron Dennis, McLaren Automotive Chairman.

The market for high performance sports cars has grown substantially since the turn of the century. McLaren divides the market into segments that encompass both comfort–orientated GT cars and the hard-edged supercars for road and track use.

The ‘core’ segment runs from around £125,000 to £175,000 featuring the Ferrari F458, Lamborghini Gallardo, Porsche 911 Turbo, Bentley Continental GT and Aston Martin DB9.

A second segment is the ‘high’ category with prices ranging from £175,000 to £250,000 and consists largely of front-engined GT cars such as Ferrari’s 599GT and 612, with just one mid-engined contender, the Lamborghini Murcielago.

The final segment is the ‘ultimate’ group, a sector initiated by the McLaren F1 in 1993 and now populated by a select group of cars including the Mercedes-Benz SLR McLaren, Bugatti Veyron, and cars from the likes of Pagani and Koenigsegg that followed legends such as the Porsche Carrera GT and Ferrari Enzo. In 2011, McLaren will bring technology and performance exclusive to this ‘ultimate’ sector into the ‘core’ segment.

Exclusivity guaranteed

Although the recent economic downturn has affected the performance car sector, just as it has the entire motor industry, McLaren Automotive believes that the ‘core’ segment’s growth from 8,000 sales in 2000 to more than 28,000 in 2007 highlights the potential that exists and that it will soon return to at least 2007 levels.

“By the time the 12C is launched in 2011 we expect the economic conditions to be much improved. We have already seen significant interest in the car and the supply of the 12C will be relatively scarce; in its first year we plan to produce just 1,000 cars which represents only 3.5 percent of the ‘core’ market,” explained Antony Sheriff, McLaren Automotive Managing Director.

“We have created ground-breaking new technology, lightweight engineering solutions, and harnessed real-world motor racing applications. It brings new levels of performance, fuel efficiency and practicality to 12C’s segment. And it will be more exclusive than its principal competition with a price that reflects its lack of ubiquity,” he said.

McLaren Automotive will distribute the 12C and future models through a brand-new retail network in all global markets.

Exclusivity, exquisite design, and a passionate focus on delivering a wonderful ownership experience will ensure that the small number of retailers around the world are taking on an attractive new brand. This approach will drive excellent customer service and a virtuous circle that retains McLaren customers and brings in new converts as the range expands.

What's in a name?

The name of the new McLaren sports car is MP4-12C. What does this signify? As one might expect at McLaren everything has a purpose and the nomenclature is no exception.

‘MP4’ has been the chassis designation for all McLaren Formula 1 cars since 1981. It stands for McLaren Project 4, resulting from the merger of Ron Dennis’ Project 4 organisation with McLaren.

The ‘12’ refers to McLaren’s internal Vehicle Performance Index through which it rates key performance criteria both for competitors and for its own cars. The criteria combine power, weight, emissions, and aerodynamic efficiency. The coalition of all these values delivers an overall performance index that has been used as a benchmark throughout the car’s development. It represents power and efficiencies.

The ‘C’ refers to Carbon, highlighting the unique application of carbon fibre technology to the future range of McLaren sports cars.

The elements of this name represent everything that the McLaren MP4-12C stands for:

‘MP4’ represents the racing bloodline

‘12’ represents the intense focus on complete performance

‘C’ represents the revolutionary Carbon MonoCell

“We are very proud of the McLaren MP4-12C and all the teamwork, intelligent thought and sheer effort that has gone into developing this car. What drives people at McLaren is passion – if you cut them, they bleed McLaren. And there is no doubt in my mind that the 12C fully reflects that focus, drive and determination in its performance, style and ownership potential,” said Ron Dennis McLaren Automotive Chairman.

Adding lightness

Light weight and performance are defining philosophies at McLaren. But outright power alone is of little significance if a car’s weight saps output or if that power is unmanageable and compromises the driving experience or results in unacceptable emissions.

Fundamentally, it is critical to keep weight as low as possible. Increased customer demands for safety and advanced features all mean that shaving weight is difficult. However, at McLaren saving weight remains a passion and at the heart of the McLaren MP4-12C is a carbon fibre composite chassis: the Carbon MonoCell.

This revolutionary structure is the automotive version of a McLaren motor racing innovation from the 1981 MP4/1 Formula 1 car. It is not only the nucleus of a fast, safe, clean and light car, but through its revolutionary one-piece moulding manufacturing technique, also presents a unique structure that allows greater freedom for innovative packaging and interior design.

The MonoCell allows for a creativity of interior design that sets new standards. The whole focus is on making the 12C cockpit uniquely spacious and functional – in car that is actually narrower than competitors. The interior styling then offers a symmetry that wraps around the occupants and makes them feel physically and emotionally comfortable.

The interior uses space well and is designed to accommodate 98^thpercentile adults in comfort. This has been partly achieved by the touch screen telematics system oriented in ‘portrait’ mode. This is a first for the car industry and is more logical - we read down a page and our mobile telephones and other personal information devices are configured this way.

This is one reason why the 12C design is able to buck the trend towards ever wider sporting cars. The innovative information centre provides all normal telematics functions such as audio, navigation and telephony, while providing some new features never before seen in a car. Meridian, the renowned producer of state-of-the-art sound systems, is developing its first ever in car system for the 12C.

Carbon original

The McLaren MP4-12C MonoCell, or 'tub', not only brings dynamic benefits, but also offers fundamental engineering opportunities that form the basis of the car’s unique character. It has been designed to allow a much narrower structure overall which in turn contributes to a more compact car that is easier to position on the road and more rewarding to drive.

This is the first time a car in this market segment has been based around such a strong and lightweight racing car engineering solution and the first time any car has ever featured a one-piece carbon fibre structure. This step change in sports car design means that the 12C introduces new standards not just in handling, ride and outright performance, but also economy and practicality in an already very competitive sector.

The 12C MonoCell  also offers greater occupant safety because it acts as a safety survival cell, as it does for a Formula 1 car.

“The whole 12C project is based on the concept of the MonoCell. This means that McLaren can launch into the market with greater performance than our rivals and a safer structure, said Claudio Santoni, McLaren Automotive Body Structures Function Manager.

Design principles

The McLaren MP4-12C design follows similar principles to McLaren’s Formula 1 cars, and the legendary McLaren F1, where everything is for a reason and all lines, surfaces, and details are designed with a job in mind as much as styled.

Frank Stephenson, McLaren Automotive Design Director, explained: “Many sports cars and super cars present an ‘in-your-face’, ‘look-at-me’ image that can become wearing and boorish; the ultimate backhanded compliment becomes, “…it was of its time”. Great design, however, is timeless and looks relevant years later. With the 12C we have produced a car that looks great today and will still look great in years to come.”

The 12C’s body has been styled to support sector-leading levels of downforce. This  downforce contributes to sector-leading levels of lateral grip and stability. Air flow has been manically managed to support all performance figures and light weight targets. For example, placing the radiators adjacent to the engine keeps the car narrow and reduces weight. However, this results in a huge challenge of ensuring ample air flow to the radiators. The result? The large side air scoops and integrated turning vanes that are dramatic, but purely functional. No larger or smaller than required.

The designers’ challenge is to then take that styling purpose driven by engineering aspirations and add personality. That’s why the air scoops resemble the McLaren logo in form, as do other features around the car.

The inside story

Packaging was fundamental to the McLaren MP4-12C design challenge. Externally, the car had to be compact, yet internally it had to offer an unparalleled driver and passenger environment where comfort and driving enjoyment were not compromised.

“With the interior, we have created a real step forward in the packaging of a sports car. Moving the driver and passenger closer together improves driving control, but comfort levels are segment-leading.

"We also repackaged many of the major components that normally sit under the dashboard to allow for more space and a unique form. For example, we designed a small, bespoke air-con unit that has been moved outside of the cockpit. Such a solution is unique in sports car design and highlights how packaging is one of the 12C’s really strong points,” said Frank Stephenson, McLaren Automotive Design Director.

Visibility is important in any road car but often in the sports car segment it proves disappointing. Accordingly, McLaren designers paid great attention to all-round visibility for both safety and driving precision.

The low windscreen cowl is inspired by the McLaren F1 and, importantly, allows the driver a clear view of the front of the car. The view of the top of the front wings also facilitates perfect placement of the 12C in a corner as the highest point of the wing lies directly above the centre of the wheel. Rear vision is excellent too making the 12C the most useable and enjoyable high performance sports car in its segment.

Defining philosophies

Light weight and performance are defining philosophies at McLaren. But outright power alone is of little significance if a car’s weight saps output or if that power is unmanageable and compromises the driving experience or results in unacceptable emissions.

Fundamentally, it is critical to keep weight as low as possible. Increased customer demands for safety and advanced features all mean that shaving weight is ever more difficult. However, at McLaren saving weight remains a passion and at the heart of the McLaren MP4-12C is a carbon fibre composite chassis: the Carbon MonoCell or `tub'.

This revolutionary structure is the automotive version of a McLaren innovation that started with Formula 1 back in 1981 and delivers  weight savings, performance gains and occupant safety. It is a technology cascade in which McLaren brought carbon composite technology from the aerospace industry to make the MP4/1 F1 car, the first Formula 1 car to benefit from the strength, weight and safety of carbon fibre (CF).

The MonoCell weighs less than 80kgs. CF contributes to the car’s low overall weight and it forms the structural basis for the whole car. The tub’s torsional rigidity is considerably stiffer than a comparable alloy structure.

Lack of flex means the unique front suspension system, which is mounted directly onto the MonoCell, requires less compromise for flex of the suspension itself. Therefore, it is easier to develop the unique balance between fine ride and precise handling that McLaren has targeted.

Proactive chassis control

The suspension for the McLaren MP4-12C breaks new ground, offering hitherto unseen levels of roll control and grip.

The car's extreme levels of dynamic handling performance would normally imply a rock-hard ride, but the 12C delivers compliance and ride comfort more akin to an executive saloon car. The mix of occupant cosseting and sporting potential is truly unique. The 12C offers the driver both class-leading ride comfort and class-leading performance.

The 12C is poised and balanced whether negotiating high or low speed corners, during direction changes, under heavy or light braking and on tightening or opening corners.

The suspension is based on double wishbones with coil springs. The dampers are interconnected hydraulically and provide adaptive responses depending on both road conditions and driver preference.

The system features adjustable roll control which replaces the mechanical anti-roll bars that have been a standard feature of road cars since time immemorial. It allows the car to maintain precise roll control under heavy cornering while decoupling the suspension in a straight line for excellent wheel articulation and compliance.

Another feature that helps the 12C to handle at a new level is a development of an electronic system used by McLaren’s 1997 MP4/12 Formula 1 car, – Brake-Steer. In essence it is a system that brakes the inside rear wheel when the car is entering a corner too quickly to make the desired radius.

Unique power unit

The McLaren MP4-12C is powered by a twin-turbocharged, 3.8 litre 90⁰ V8 engine - the ‘M838T’. This marks the start of a new era in ‘core’ segment sports cars - smaller capacity, lighter weight, higher efficiency and more economical power units. The engine has the highest specific power output in its segment which, when allied to its low weight carbon composite chassis, delivers exemplary power- and torque- to weight ratios.

‘M838T’ is a unique McLaren power unit, developed specifically for the 12C. It is compact, lightweight, very stiff, and offers an uncompromising combination of high performance and good driveability with excellent economy and CO2 emission values.

Taking power and emissions in combination the 12C delivers its power at greater efficiency than any other car on the market with an internal combustion engine, including hybrids.

‘M838T’ features dual variable valve timing and produces around 600bhp and 600Nm of torque. A dry sump and flat plane crankshaft allow the engine to be placed extremely low in the chassis thereby lowering the centre of gravity and improving handling responses. It also features composite cam covers and intake manifolds, which reduce weight and heat transmission into the charge air.

The engine revs to 8,500rpm, has quick transient throttle response and delivers its abundant torque throughout the rev range. A staggering 80 per cent of torque is available at below 2,000rpm, ensuring great driveability and no need to floor the throttle to deliver performance.

Seamless Shift Gearbox

Gears are changed using a Formula 1 style rocker shift that pivots in the centre of the steering wheel. It is actuated on either side of the steering wheel.

As with the McLaren Formula 1 car, a shift can be actuated either by pulling or by pushing on the rocker. The rocker moves with the steering wheel, rather than being mounted on the steering column, so that if a gear change is needed while lock is being applied the driver does not have to fumble around to change gear.

The rocker itself incorporates an innovative feature created by McLaren engineers called Pre-Cog. The name stands for pre-cognition, literally ‘foreknowledge’. The rocker on the 12C has two positions with a slightly different haptic (or feel) for each. The driver applies first pressure to the rocker and it informs the gearbox to get ready to swap ratios, thereby saving a small amount of time between the message being sent and the gearbox being primed to act. The second pressure confirms that the gear should be changed and the torque handover is completed very quickly.

“What Pre-Cog actually does is initiate the shift process by priming the clutch and torque handover – it takes significant time out of the process,” explained Dick Glover, Technical Director McLaren Automotive. “It’s a little bit like the first pressure on a camera shutter button. There’s no requirement for the driver to use it but it is more satisfying and engaging if you do.
