Opel Astra OPC Extreme
The Opel Astra OPC Extreme, which makes
its world premiere at the 2014 Geneva Motor Show, is a real race-bred
performance car. Developed on the Nürburgring Nordschleife, the most
challenging race track in the world, it is powered by a 2.0-liter turbo engine
with over 300 hp and equipped with all the key high-tech components from its
racing peer, the Opel Astra OPC Cup. The Astra OPC Extreme was developed
directly from the Cup version and brings pure racing technology to the road.
Over 300 hp will be unleashed from under
the Extreme's carbon fiber hood. Its 2.0-liter turbo gasoline engine, with
direct injection and variable camshaft phasing, is quite simply the most
powerful four-cylinder unit Opel has ever produced. The all-aluminum engine is
mated to a slick, six-speed manual gearbox transmitting power through a
limited-slip differential. This race-proven powerplant will have an easy time
of it with the OPC Extreme, because the super sporty car is 100 kilograms
lighter than a conventional Astra OPC thanks to its high-quality, carbon fiber
components.
Widely used in Formula 1 racing to
reduce weight, carbon composite is incorporated throughout the Extreme. This
high-strength, ultra-light material is used for the aerodynamically-optimized
rear wing, the diffuser, front spoiler, hood, suspension cross-bracing, the
engine cover, complete wheels, rear wheelhouse ventilation and roof. The carbon
wheels are 20 kilograms lighter than their aluminum counterparts. This is
weight saving in a decisive area because unsprung mass is substantially reduced
- much to the joy of engineers and driving fun of drivers. The inhouse
manufactured carbon fiber roof is almost as light as a feather. It weighs just
2.6 kilograms, compared to a steel roof's 9.3 kilograms, and noticeably lowers
the Astra Extreme's center of gravity. The fenders are made of aluminum and
weigh only 800 grams a piece instead of 2.2 kilograms in steel.
Weight reduction in key areas greatly
improves agility, overall handling and, of course, the car's power-to-weight
ratio. As a result, the street-legal Extreme sweeps through fast curves as
playfully and quickly as its racing brother in the Nürburgring Endurance
Championship (VLN). Opel has also given the Extreme breathtaking stopping power
to match, with a Brembo six-piston brake system including 370 mm diameter discs
up front race car. Ultra high-performance, 245/35, 19-inch tires, 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 chassis (spring/damper) is adjustable,
just like in a real touring car racer.
The pursuit of uncompromised performance
continues in the design of the Extreme'S cabin: the back seats are out and a
safety roll bar is in. The driver and co-driver are perfectly positioned in
specially-designed Recaro bucket seats, complete with six-point safety belts
from Schroth. In the Astra OPC Extreme, the crew doesn't just sit in the car,
they are fully integrated as part of the vehicle itself. The driver also has
the tactile pleasure of gripping a superb, carbon-fiber-reinforced,
suede-covered steering wheel with fine yellow decorative stitching. Opel
Motorsport's core color also dresses up the Astra OPC Extreme elsewhere, for
instance in the exclusively designed logo and as lacquer on the side sills and
front spoiler lip.
Apropos lacquer, the Astra GTC body
format - the base model for the OPC Extreme - ideally embodies Opel's
sculptural design philosophy. Its flowing, sculpted shapes and precise accents
blend into dramatic proportions. The Astra OPC Extreme's multi-layer paint
lacquer is combined with high-quality decal details to give a three-dimensional
effect, further emphasizing the car's clean edges, bold lines and athletic
proportions.
