2011 Mazda MX-5 GT Race Car

This is the new Mazda MX-5 GT, the fastest, lightest Mazda-produced MX-5 ever. Unfortunately, it's also the company's new entry for this year's Britcar MSA British Endurance Championship, so you won't be seeing it on the road anytime soon.

Designed to compete in this year’s Britcar MSA British Endurance Championship, the standard MX-5 has been completely reworked to FIA specifications. It features a modified version of Mazda’s 2.0-litre in-line four, developing 275bhp - up 117bhp on the road going version - and mated to a six-speed sequential paddle shift ’box.

The car is also fitted with FIA-spec gear such as roll cage, racing seats with harness, external electric cut-off and fire extinguisher, competition alloy wheels and steering wheel, and safety latches for the bonnet and boot lid.

Under the bonnet is seriously tuned and tweaked 2.0-litre engine. Rather than 158bhp the four-cylinder engine now produces 275bhp. It also sits lower in the racer, and drives the rear wheels via a six-speed sequential gearbox.

The Mazda MX-5 GT will compete in its first race at the Britcar MSA British Endurance Championship three-hour endurance race at Silverstone, scheduled to start at 3:00pm on March 26.

MAZDA MX-5 GT BREAKS COVER

• Mazda MX-5 GT entry into Britcar MSA British Endurance Championship 2011
• Lightweight Mazda MX-5 GT race car to challenge conventional thinking
• Mazda MX-5 GT remains true to its roots but with more power and performance

Mazda is set to challenge Aston Martin, Porsche, Lotus, and BMW on the race track with its lightweight Mazda MX-5 GT entry in the Britcar MSA British Endurance Championship 2011.

Weighing in at just 850kg, the Mazda MX-5 GT race car will accelerate from 0-to-60mph in just three seconds and hit a top speed of 160mph. The build of the car has been an engineering challenge to get the weight as low as possible using Mazda's gram strategy as the inspiration. Jota Sport examined every nut and bolt to reduce component weight and then match the power to the weight to give the lightest and most powerful MX-5 ever built.

An important aspect of the build was to ensure the Mazda MX-5 still remains true to its roots: great handling, huge fun-to-drive and the ability to challenge bigger more powerful competition, but at an affordable cost. The Mazda GT car ticks all those boxes and is now set to demonstrate its challenger spirit on the track.

Jota Sport, the race engineering team that will run the cars in the 2011 series, took 400 hours to build the shell to a specification that ensured it was 17 times stronger than required by the FIA. During the development they faced a number of engineering challenges such as suspension adjustments, integrating the six speed sequential gearbox, and lowering the engine. Weight saving strategies such as, the removal of interior components, reducing component weight and dipping the shell in acid lost 15kg from the MX-5 race car.

The completed MX-5 GT features a modified Mazda engine to produce 275bhp, a six speed sequential paddle shift gearbox, carbon doors and Polycarbonate windows. On the exterior, the Mazda MX-5 GT boasts a Spirited Green metallic body colour - a first on the MX-5 for Mazda UK - complimented by Jota Sport corporate coloured liveries in orange and grey.

Mazda is renowned for challenging conventions so the motivation to develop a MX-5 GT car comes naturally. It also comes at a time when Mazda has recently celebrated a number of milestones for MX-5 including its 21st anniversary and producing 900,000 MX-5 units globally since its introduction in 1989, with over 10 percent of global MX-5 sales from Britain. Meanwhile, the Mazda MX-5 continues to hold the Guinness World Record as the world's best?selling roadster - testament to its continued popularity with British open top sports car fans.

The Britcar MSA British Endurance Championship is contested over nine races from March to November including a race at the Spa Francorchamps circuit in Belgium. The first race is a three hour endurance race at Silverstone next weekend, Saturday 26 March 2011, starting at 3.00pm.

This is the fourth time that Mazda has entered Britcar and this year the Mazda MX-5 GT car will be driven by two Mazda works drivers including experienced Mazda racing driver Mark Ticehurst, 39 from Hassocks, West Sussex and Auto Express journalist and racing driver Owen Mildenhall.

"The MX-5 production race car's modest power output, bullet proof reliability and nimble handling demonstrated last year how the MX-5 can be competitive against some of the purpose-built Lotus, VW and BMW race cars. With a higher power output combined with the durability, reliability and handling attributes that the MX-5 is renowned for; the MX-5 GT race car will be strong contender against the more powerful race cars in its class," comments Graeme Fudge, PR Director, Mazda UK.

The Mazda MX-5 GT car, prepared by Tunbridge Wells-based Jota Sport features the mandatory FIA approved safety equipment including a roll cage, race seats and harness, external electric cut-off and fire extinguisher, safety catches on the bonnet and boot lids, competition steering wheel and alloy wheels, while the running gear, rear axle, gearbox and engine have been modified to enhance performance.

Porsche 911 GT3 R Hybrid Version 2.0

Porsche has announced that they will be entering an improved version of the Porsche 911 GT3 R Hybrid into the upcoming Nürburgring 24 hour race on June 25, 2011. Priority of the new car’s development was given to the improvement of efficiency through the targeted optimization of hybrid components, which also resulted in a 20 percent weight reduction. Version 2.0 of the 911 GT3 R Hybrid is intended to achieve the same lap times as its predecessor but with even less fuel consumption.

The Porsche 911 GT3 R Hybrid Version 2.0 is powered by a hybrid system that combines a 480 HP 4.0 Liter flat six engine placed in the rear with two electric motors that drive the front wheels. The two motors will add an extra 200 HP (100 hp each) as opposed to the 150 HP offered on the first model. This power is automatically activated through the throttle pedal and can be quickly called upon when zipping around a competitor. Other than situations where the extra power can be used to overtake the competition for a few seconds, the Porsche will rely on the 4.0L engine for its stamina.

The other main difference with the new hybrid system is that the flywheel accumulator and other hybrid system components will be housed in a new carbon fibre safety cell positioned in the passenger-side area of the interior. This means these components, previously exposed to heat, won’t need to be cooled by aerodynamic-hindering large vents in the rear haunches. This means Version 2.0 will more slippery through the air.

Overall, the new 911 GT3 R Hybrid Version 2.0 now weighs 1300kg, a 50kg reduction from the previous car's weight of 1350kg. The interior has also been updated, with the displays and controls moved to the steering wheel. According to Porsche, drivers can operate the rest of the functions via backlit buttons now situated on the centre console.

Nürburgring 24 hour race

Porsche lines up with an even more efficient 911 GT3 R Hybrid

Stuttgart. Porsche takes up the Nürburgring 24 hour race on 25 June with a further developed version of the Porsche 911 GT3 R Hybrid. Priority of the development was given to the improvement of efficiency through the targeted optimisation of hybrid components, which also resulted in a 20 percent weight reduction. Version 2.0 of the 911 GT3 R Hybrid is intended to achieve the same lap times as its predecessor but with less fuel consumption.

The general layout of the hybrid was adopted from the 2010 model. A portal axle with two electric motors drives the front wheels and supplements the four-litre, depending on the balance of performance classification approximately 470 hp, six-cylinder boxer engine at the rear. The output of both electric motors has increased from 60 to 75 kilowatts each. For seconds at a time, pilots now have almost an additional 200 hp at their disposal with the 911 GT3 R Hybrid 2.0. Depending on the programming, this power is automatically activated through use of the throttle pedal. Moreover, pilots can manually call up this extra power, for instance when overtaking.

The electric flywheel accumulator, with its rotor spinning up to 40,000 rpm and stor-ing energy mechanically as rotational energy, is now housed with the other hybrid components in a carbon fibre safety cell on the passenger's side.

At first glance, the new GT3 R Hybrid is clearly distinguishable from the 2010 model. Thanks to the optimisation of the hybrid system's high voltage components, the large louvres in front of the rear fenders were no longer necessary. This reduces drag and also lowers fuel consumption. All in all, the weight of the vehicle decreased from 1,350 to 1,300 kilograms.

"We've collected a great deal of information from our races on the Nürburgring, at the ALMS race at Road Atlanta in the USA, as well as from the ILMC race on China's Zhuhai circuit, which was an invaluable help for the further development of our racing laboratory," says Hartmut Kristen, head of Porsche motorsport. "The emphasis of our work was on improving efficiency. That means we want to keep the lap times consis-tent with 2010 but use less energy, hence less fuel. In this way, we support future developments of road-going, sporting hybrid vehicles."

The cockpit of the 911 GT3 R Hybrid has also been completely revised. Most of the displays and controls have moved to the steering wheel. Drivers can operate the rest of the functions via backlit buttons now situated on the centre console. Priority was placed on the ergonomics and the clear layout for pilots - particularly in darkness.

The new 911 GT3 R Hybrid is a perfect example of the ‘Porsche Intelligent Perform-ance' philosophy, a principle found in every Porsche: More power on less fuel, more efficiency and lower CO2 emissions - on the race track and on the road.
