About Audi A4
The engine lineup received many additions. The 2005 introduction of Fuel Stratified Injection (FSI) on the 2.0 TFSI and 3.2 V6 FSI petrol/gasoline engines, as well as other refinements, increased power output to 200 PS (147 kW; 197 bhp) and 255 PS (188 kW; 252 bhp), respectively. These engines both use a four-valve per cylinder configuration. The prior 5-valve design was incompatible with the FSI direct injection system (due to the siting of the fuel injector, now discharging directly into the combustion chamber). The 2.0 Turbocharged Direct Injection (TDI) diesel engine now combined Pumpe Düse (Unit Injector) (PD) technology with 16 valves, while the larger 2.5 TDI V6 diesel was superseded by a 3.0 V6 TDI, offering a 204 PS (150 kW; 201 bhp) model during the year 2005 which was upgraded to a 233 PS (171 kW; 230 bhp) model in 2006. A 2.7 V6 TDI was added later.
Torsen T-2 based quattro permanent four-wheel drive remained as an option on most A4 models. Audi retired its 5-speed manual transmissions in favour of a new Getrag 6-speed. As before, multitronic continuously variable transmission (CVT), now with selectable ‘seven-speeds’, was an option on front-wheel drive models, whilst a conventional ZF 6HP 6-speed tiptronic automatic transmission was an option on the quattro four-wheel drive models.
