2011 ASTON MARTIN VANTAGE GT4
2011 Aston Martin Vantage GT4 with 4.7 litre and new V8 engined racing car takes design inspiration from Aston Martin V12 Vantage road car.
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.
The 2011 car is closely based on the V8 Vantage road car with key attributes being carried over including the aluminium 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 optimised by Bosch Motorsport to provide race-enhanced performance in both wet and dry conditions.
At the front car the Aston Martin Vantage GT4’s new splitter increases downforce as well as channelling 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 fibre diffuser and rear underfloor, which create an area of low pressure under the rear of the car, to increase downforce.
2010 GMC SIERRA HYBRID CREW CAB
GMC Sierra Hybrid Crew Cab is a powerful full-size pickup that achieves 40-percent greater city fuel economy and a 25-percent improvement in overall fuel economy while delivering the capability expected of a full-size truck including a 6,100-pound (2,767 kg) towing capacity.
Thanks to the two-mode hybrid system and a powerful 6.0L gas V-8, the Sierra Hybrid delivers highly efficient performance, including all-electric driving up to 30 mph (48 km/h). Sierra Hybrid will deliver fuel economy that is expected to be the best in the full-size pickup segment, exceeding the current mileage leader the non-hybrid Sierra.
It will be offered in the Crew Cab body style on both 2WD and 4WD models. Each model is equipped with several standard, popular features, including StabiliTrak electronic stability control system, a locking rear axle and a trailering package. Sierra Hybrid also offers dual-stage frontal air bags and head curtain side air bags.
The Sierra Hybrid’s fuel-saving performance is derived from GM’s advanced Electrically Variable Transmission (EVT) and 300-volt nickel-metal hydride Energy Storage System (ESS), which work in concert with the standard 6.0L V-8 gasoline engine with Active Fuel Management (AFM) and late intake valve closing (LIVC) technology. GM’s hybrid technology system not only enables the Sierra to launch and drive up to 30 mph on electricity alone, it also allows the Vortec 6.0L V-8 engine to operate in its more economical V-4 mode for longer periods.
