Our skepticism centers on the engine bay, where Audi once again sends its
turbocharged four-cylinder power plant up against the six-cylinder
competition. While the revised 2.0T gets the job done at the test track, it
sounds like a Civic, and the steering wheel vibrates with four-cylinder
fervor at full throttle. We suspect many shoppers will want a more refined
engine at this price point, particularly given the polished company the A4
keeps.

While the 2.0T has an admirably linear power delivery that belies its
turbocharged identity, it doesn't feel that quick in real-world driving --
our seat-of-the-pants impressions had us expecting a 0-60 time in the low 7s
. What gives? Turns out Audi has stacked the deck by endowing the
transmission with an unadvertised drag-strip mode.
If you deactivate stability control, depress both the brake and throttle and
then release the brake when the engine speed stops rising -- a process
known as "brake-torquing," which is standard procedure for our track drivers
-- the transmission bangs off uniquely quick and harsh upshifts that occur
at least 500 rpm sooner than usual, presumably to keep the turbo boost from
tailing off near redline. The resultant eye-catching acceleration times mask
the fact that the A4 feels a step behind its six-cylinder rivals outside
the confines of a racetrack. | B*******a

现在这代A4是2009年换代的，也就是说现在A4仍然有这个弄虚作假问题。 |
