Audi introduced a redesigned A4 in late 2004, now
riding on the B7 platform, which is completely unique
to Audi and not shared with Volkswagen. Nonetheless,
the B7 is really a revision of the outgoing B6,
and not a ground-up redesign. This is confirmed
by Audi's internal platform nomenclature, which
uses PL46 (longitudonal passenger car platform,
size 4, generation 6) for both B6 and B7 chassis.
The engine lineup received many
additions, the most notable of which was the introduction
of Fuel Stratified Injection on the new 2.0 TFSI
and 3.2 V6 FSI, respectively capable of 200 and
255 PS (147 and 188 kW), although these engines
dropped the five-valve design in favor of the
more widely known four valves per cylinder configuration,
as the design was incompatible with the direct
injection system. The new 2.0 TDI engine now combined
Pumpe Düse (PD) technology with 16 valves
for the first time, while the larger 2.5 TDI was
increased to 3.0 L, with 204 PS (150 kW).
