With everybody bringing their best bets to the upcoming Geneva Motor Show, British car manufacturer Vauxhall decided not to be left behind with the new Vauxhall Astra VXR Extreme, a lightweight street-legal track toy that takes the moulding of the Astra Cup race car that competed in the Nürburgring Endurance Championship.
The main principle of the Extreme lies in its weight – it has lost 100 kg over the standard model, thanks to extensive applications of carbon fibre and lightweight materials on the roof, hood, rear wing, diffuser, front spolier and engine cover. Even the suspension bracing and wheels are made of lightweight materials.
Similar story on the inside, where the back seats have been replaced with a safety roll bar. The car also gets Recaro bucket seats, with six-point safety beltsand a carbon-fibre-reinforced steering wheel covered in suede.
Not much information on the power train, but Vauhxall boasts that the Extreme will be the most powerful front-wheel drive the company has ever produced with over 300 hp from its 2.0-litre turbocharged engine, that is mated to a six-speed manual gaerbox and LSD. The car is fitted with Brembo six-piston brakes behind the 245/35 R19 tyres and adjustable dampers a la real touring car.
In terms of availability, Vauxhall is letting the public to decide. Positive feedback could send the car to the production line, albeit in small quantity.
FULL REVEAL OF VAUXHALL’S RADICAL GENEVA STAR
Luton – With over 300PS generated from its 2.0-litre turbo engine, the Vauxhall Astra VXR EXTREME will be the most powerful front-wheel drive Vauxhall ever when it’s unveiled at the Geneva Motor Show next month.
Derived from last year’s Astra Cup race car that competed in the Nürburgring Endurance Championship, the EXTREME is the lighter, more powerful street-legal race sibling to the current Astra VXR.
Shorn of 100kg, thanks to liberal use of high-quality carbon components, the EXTREME’s natural environment will be the race track. If public reaction is as positive as expected, Vauxhall plans a low-volume production run for the EXTREME.
With direct injection and variable camshaft phasing, the EXTREME’s 2.0-litre turbo petrol engine is the most powerful four-cylinder unit Vauxhall has ever produced. The all-aluminium engine is mated to six-speed manual gearbox transmitting power through a limited-slip differential.
The EXTREME is 100kg lighter than a standard Astra VXR thanks to its high-quality, carbon fibre components. This high-strength, ultra-light material is used for the aerodynamically-optimised rear wing, the diffuser, front spoiler, bonnet, suspension cross-bracing, engine cover, wheels, rear wheelhouse ventilation and roof.
Noticeably lowering the EXTREME’s centre of gravity is the in-house manufactured carbon fibre roof which weighs just 2.6kg, compared with a steel roof’s 9.3kg. The wings are made of aluminium and weigh only 800g a piece instead of 2.2kg in steel. Weight reduction in key areas greatly improves agility, overall handling and the car’s power-to-weight ratio.
Vauxhall has also given the EXTREME exceptional stopping power to match, with a Brembo six-piston brake system including 370mm diameter discs up front race car. Ultra high-performance, 245/35, 19-inch tyres, specially developed for the EXTREME, also play a key role and give almost as much grip as those on the race car. In addition, the damper is adjustable, just like in a real touring car racer.
Inside the EXTREME, the back seats have been taken out and a safety roll bar put in their place. EXTREME also gets Recaro bucket seats, with six-point safety belts from Schroth and a carbon-fibre-reinforced, suede-covered steering wheel with fine yellow decorative stitching.
The Astra VXR is now the best-selling VXR and the UK remains the largest market in Europe for Vauxhall and Opel’s highest powered models.
