Aston Martin Rally GT Racing V8 Vantage


Aston Martin Rally GT V8 Vantage

The Aston Martin Rally GT, based on the Aston Martin V8 Vantage, was developed by Aston Martin Racing and automotive engineering specialists Prodrive (see Prodrive P2) for use in rally racing.

The Aston Martin Rally GT was extensively engineered by Prodrive, and like the DBRS9 based on the Aston Martin DB9, the Rally GT is based on a standard road car's chassis. However the Rally GT has been fitted with a Prodrive rollcage, a tuned and more responsive version of the standard car's 4.3 litre V8, and new competition Eibach springs and adjustable EXE-TC dampers. The 6-speed transmission is the same unit found in the road car, but it can be upgraded to a close ratio dog engagement gearbox specifically developed for the Aston Martin Rally GT.

2010 BMW Z4 Roadster is the first all-new, top-to-bottom redesign of the Z4 model which was originally launched in 2002.
The 2010 Z4 has a sleeker profile and more subtle "flame surfacing" body lines than the previous model. In general the car has a more balanced and matured appearance to it. That's not to say the roadster has lost any of its visual appeal, it's just been refined and tweaked to fit better with the current BMW styling direction.
The front end of the 2010 BMW Z4 has undergone the most obvious transformation. The headlights are thinner and sweep back further into the wheel arches, and the trademark BMW kidney grilles have been elongated to better match the headlights. Down the sides the controversial styling slash which intersected the fender mounted BMW badge has been replaced by a more conventional panel. The BMW badge is now fitted just forward of the doors and adjacent to the side indicators which are cleverly integrated into the metalwork.
Unlike the original Z4 Roadster which used a fabric roof, the 2010 model is fitted with a retractable metal roof which folds away neatly into the rear storage area. 20 seconds is all it takes for the roof to electronically raise or lower itself.
The 2010 BMW Z4 is offered with a choice of three different engine options. The Z4 sDrive23i model is equipped with a 2.5 litre inline 6 cylinder which develops 204 horsepower. The Z4 sDrive30i is fitted with a 258 horsepower / 228 lb-ft of torque naturally aspirated 3.0 litre 6 cylinder. The top level Z4 is the sDrive35i version which is powered by a twin-turbocharged, 3.0 litre, inline 6 cylinder which pumps out 306 horsepower. With this engine the Z4 can hit 62 mph in just 5.1 seconds. The Z4 can be fitted with either a 6 speed manual gearbox or a 7 speed dual-clutch transmission.
