Aston Martin Racing has launched a new Vantage GT4 for 2011. The new V8
engined racing car takes design inspiration from Aston Martin's V12 Vantage road
car, giving it enhanced aerodynamics and increased downforce. It also has a
remapped 4.7-liter engine offering increased levels of power and torque.
Aston Martin Racing has built and sold more than 80 Vantage GT4s to
customers around the world in the last two years and it has become the most
successful car in its class. In 2010, it won the European GT4 Cup as well as the
GT4 class at the Dubai 24 Hours, the Nürburgring 24 Hours and the Spa 24 hours.
The car also has its own one-make series, the Aston Martin GT4 Challenge of
Great Britain, which was won in its inaugural year by Chris and Ant Scragg. The
new Vantage GT4 will be eligible for this Challenge, as well as the European GT4
Cup and all other series with a GT4 class.
As with the current 4.7-liter Vantage GT4, which made its race debut in 2009, the 2011
car is closely based on the V8 Vantage road car with key attributes being
carried over including the aluminum chassis, base engine and suspension design.
In addition to the engine and aero upgrades, competitors can, for the first
time, choose a race-developed Bosch ABS and traction control system. This system
has been specifically optimized by Bosch Motorsport for the Vantage GT4 to
provide race-enhanced performance in both wet and dry conditions.
The
Vantage GT4's new splitter increases downforce at the front of the car, as well
as channeling cooling air to the brakes and radiator. At the rear, the car
gains the V12's larger boot 'flip'. This works together with a new carbon-fiber
diffuser and rear underfloor, which create an area of low pressure under the
rear of the car, to increase downforce. The redesigned underfloor also channels
more air through a new rear-mounted high capacity transmission oil cooler.
