Mk5 GT
The Golf Mk5 GT features a choice of either 1.4 L petrol engine in twincharger (TSI) configuration, or a 2.0 litre TDI diesel engine. Both petrol and diesels are available as 125 kW (170 PS; 168 bhp) versions. The diesel has 350 N·m (258 ft·lbf) of torque, which is more than the range topping R32. The petrol engined offering contains the new TSI engine, which is based on the recent Fuel Stratified Injection (FSI), but with a pair of chargers forcing the induction of the air. The chargers are a single supercharger that disengages after a specified rev-range, at which point charging of the air is handled by a single turbocharger. This system benefits from both of the efficiency of the supercharger in the lower rev ranges, with the longevity of the turbocharger higher in the rev range. This results in little turbo lag, constant power delivery along the rev range, and better fuel efficiency than similarly powered 2.4 L V6 engine due to its small size.
Both petrol and diesel versions are also available with Direct-Shift Gearbox (DSG). Performance figures for the petrol vehicle are 0-100 km/h (62 mph) in 7.9 seconds (6-speed manual) and 7.7 seconds (DSG), with the diesel taking 8.2 seconds, and both reaching top speed of 220 km/h (136.7 mph).
The Golf GT features the same brakes as the Golf GTI, with 312 mm (12.3 in) ventilated front discs, and 286 mm (11.3 in) solid rears. It has also 15 mm (0.59 in) lowered suspension, which lowers its centre of gravity, it borrows the GTI's suspension/damper settings, uses 7Jx17" "ClassiXs" alloy wheels fitted with wide 225/45 R17 tyres, and has twin exhaust outlets.
