Aston Martin Vantage GT4 Racer Updated for 2011

Talk about symmetry. After updating its racing-inspired V8 Vantage N420 for the 2011 model year, Aston Martin announced a number of modifications for the race version -- the 2011 Vantage GT4.

As has been the case since the model's 2008 debut, the Vantage GT4 is based heavily upon the V8 Vantage, but the 2011 GT4 racer does receive a number of styling tweaks inspired by those applied to the V12 Vantage road car. Up front, the car receives a bumper fascia and splitter from the V12 Vantage parts bin, which help increase downforce while simultaneously directing air to the radiator and brake cooling ducts.

In back, the GT4 uses a taller trunk spoiler, bumper fascia, and diffuser cribbed from the V12 Vantage. Aston also says its reworked the underbody panels at the rear of the car, allowing them to channel airflow into a new rear-mounted transmission oil cooler.

Although the 2011 GT4 receives some cosmetic inspiration from the V12 Vantage, mechanically speaking, it remains true to the V8 Vantage formula. Power continues to be sourced from Aston's 4.7-liter V-8, although a remapped engine computer reportedly grants it an unspecified power increase over the 2010 model (we imagine total output is somewhere in the neighborhood of 450-500 horsepower). Like the outgoing model, the new GT4 is available with either a six-speed manual or a six-speed SportShift sequential manual transmission.

Vantage GT4 models also receive a limited-slip rear differential; a twin-plate competition clutch; four-piston, monobloc front and rear brake calipers; Brembo brake discs; and magnesium five-spoke wheels. Buyers can spring for adjustable dampers from Koni or Bilstein, rose-jointed suspension parts, a 31-gallon fuel cell, various datalogging systems, and -- for the first time ever -- a race-calibrated ABS and traction control system sourced from Bosch.

As its name suggests, the 2011 Vantage GT4 is built to meet FIA GT4 specifications, and can be raced in all GT4 events, including the European GT4 Cup and the Nürburgring 24 Hours. If that's not enough, the car will also be eligible to compete within the British GT4 Challenge, a one-make race series created and sponsored by Aston Martin itself.
