More power, less weight. It's a winning formula when it comes to performance automobiles, and one we've seen applied time and time again. It's what Ferrari did to transform the 360 Modena into the Challenge Stradale, the F430 into the Scuderia and the 458 into the Speciale. Maserati does the same with the GranTurismo MC Stradale and Lamborghini with the Gallardo Superleggera. We could go on, but you get the point: it's a formula typically applied to exotic Italian supercars, but of course it's not exclusively their realm.

Taking up the opposite end of the spectrum is the new Astra Extreme, the hardcore new hot hatch which GM's European operations will unveil shortly at the Geneva Motor Show. To be sold by Vauxhall in the UK as the Astra VXR Extreme and by Opel in Europe as the Astra OPC Extreme, the hottest of hot hatches takes the Astra Cup racer to the street with extreme aero and lightweight components.

General Motors has shed a good 100 kilograms (220 pounds) of excess weight through the use of carbon-fiber components. The roof, hood, engine cover and suspension bracing are all made of the lightweight stuff. The same goes for the aero kit, complete with front splitter, rear wing and underbody diffuser. Even the 19-inch wheels are made of carbon fiber, packing Brembo brakes that measure 14.6 inches with six-piston calipers up front. Even the cabin has been stripped out, dumping the rear seats in favor of a roll cage, with Recaro buckets and six-point harnesses up front. All that, and it's still (Euro) street legal.

Vauxhall and Opel aren't saying much about the power side of the equation, but do claim that the 2.0-liter turbo four – complete with direct injection and variable cam timing, is the most powerful it's ever made. However much power it produces, it's all channeled to the front wheels through a six-speed manual and limited-slip differential. All of which adds up to a limited-production track monster that looks ready to take on the likes of Renault and Honda for the front-drive Nürburgring lap record.

FULL REVEAL OF VAUXHALL'S RADICAL GENEVA STAR

Luton – With over 300PS generated from its 2.0-litre turbo engine, the 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.

      Why can't GM do a Golf R or Audi S3 version of this Astra? Or the Buick Verano?

        Good question. Buick needs this car to compete with Mini's JCW's Edition.

      Why won't Porsche/VW re-issue the 914 in electric car form?

      Why oh why can't Toyota/Subaru do this with the FT86?
