Audi A4 Saloon

Overview

Produced: 2004-2008
Types:
Audi A4/S4 Saloon
Audi introduced a heavily revised A4 in late 2004, with the internal designation of B7. However, this new range A4 still utilised the existing Volkswagen B6 (PL46) platform, a chassis derived from the outgoing B6, but enjoyed heavily revised steering settings, suspension geometry, new 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.

Audi's internal platform nomenclature uses PL46 (passenger car longitudinal platform, size 4, generation 6) for both B6 and B7 chassis. The Typ 8E and 8H internal designations are also carried over from the B6 A4 range, but now have an additional identifying suffix - 8EC for the saloon, 8ED for the Avant, and 8HE for the Cabriolet.

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 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). The 2.0 Turbocharged Direct Injection (TDI) diesel engine now combines Pumpe Düse (Unit Injector) (PD) technology with 16 valves for the first time, while the larger 2.5 TDI V6 diesel was superceeded by a 3.0 V6 TDI, offering 233 PS (171 kW; 230 bhp). A 2.7 V6 TDI was added later.

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) 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.

In addition to the higher-performance Audi S4, which carried over the powertrain from the B6 S4 - Audi has reintroduced the ultra-high performance Audi RS4 (RS for RennSport) to the lineup, for the first time on the saloon/sedan and Cabriolet body, and with a normally aspirated, but high-revving 4.2 V8 FSI engine. Another notable inclusion on the RS4 is the latest generation Torsen T-3 quattro 4wd system, which uses a 'default' asymmetric 40:60 front-rear dynamic torque distribution bias. This new asymmetric centre differential was initially only available on the RS4, but was added a year later on the S4. The remainder of the B7 A4 range still utilised the T-2 50:50 default dynamic split centre diff.

A limited edition variant, developed by quattro GmbH, was first introduced in May 2005, named "Audi A4 DTM Edition". It was inspired from Audi's race cars of the 2004 Deutsche Tourenwagen Masters, and was reintroduced in 2006 as a regular option. The 2.0T FSI engine received revised software mapping to the ECU, which increased the output to 220 PS (162 kW; 217 bhp) and 300 N·m (221 ft·lbf) of torque. It was available with front-wheel drive, or quattro four-wheel drive.

The B7 Cabriolet model arrived later than the other two body variants, with sales beginning in February 2006. New on the Cabriolet was an entry-level 2.0 TDI version, but to date, this is not being offered with the multitronic CVT gearbox.
