Audi introduced a revised A4 in late 2004, with the internal designation of B7. However, this new range A4 still utilised the existing Volkswagen platform, a chassis derived from the outgoing B6, but enjoyed heavily revised steering settings, suspension geometry, new internal combustion engine ranges, navigation systems and chassis electronics (including a new advanced Bosch ESP 8.0 Electronic Stability Programme (ESP) system). The front grille assembly has changed to be a tall trapezoidal shape in the same manner as the C6 (third-generation) Audi A6., , 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 (197 bhp) and ( 252 bhp), respectively. These engines both implement a four-valve per cylinder design. 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). , , Torsen T-2 based quattro permanent four-wheel drive remained available 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', is available on front-wheel drive models, whilst a conventional ZF 6HP 6-speed tiptronic automatic transmission is available on the quattro four-wheel drive models., , B7 safety, The Audi A4 offers many standard safety features, including Bosch ESP 8.0 Electronic Stability Programme (ESP) with Anti-lock Braking System (ABS), side airbags in the seats, 'sideguard' curtain airbags, and its optional quattro four-wheel drive system. It also received the Insurance Institute for Highway Safety (IIHS) "Top Safety Pick For 2007".EuroNCAP crash test results from the B6 apply to the B7 model., , , , , Transmission(s) 5 speed and 6-speed Manual, 6-speed ZF 6 hp Tiptronic, 7-speed Multitronic , Wheelbase (104.3 in) , Length (180.6 in),, Cabriolet: (180.0 in) , Width (69.8 in),, Cabriolet: (70.0 in) , Height (56.2 in),, , , 2.0T FSI quattro 200 PS (197 bhp) 7.2 sec 143.5 mph
