2010 Audi S4 to Get Supercharged V-6
HILLS, MI – The 2010 Audi S4’s powertrain will feature an all-new
forced-induction 3.0L V-6 that will generate something close to the 340
horsepower found in the outgoing S4’s 4.2L V-8. Audi’s strategy is to deliver
comparable or improved overall performance by toeing the line on weight and
maintaining power output by using forced induction on a smaller displacement
engine. Doing so will boost a manual transmission S4’s fuel economy on the
European cycle to 23.3 mpg compared with only 19.4 mpg for the V-8 S5. That’s
an efficiency gain of 20 percent, according to www.caranddriver.com.
powerful, 290-hp, 310 lb-ft version of the engine will be the base offering in
the A6 Quattro, replacing the 3.2L V-6. Known as TFSI, which in the past has
been Audi’s internal moniker for four-cylinder turbos, the new engine may be
referred to as the 3.0T in the model name, possibly indicating a twin-charged
system using both a supercharger and a turbocharger, the report said. While
Volkswagen has a “twincharger,” Audi has not yet offered such a system.
with the outgoing 2008 A4, the redesigned 2009 A4’s body is approximately 10
percent lighter. The A4 and S4 will use identical sheetmetal this time around.
Not only does the sharing save money, but stresses the exclusivity of the RS 4
which will better stand out with its distinct sheetmetal—including bulging
fenders—and a V-8.
Car and Driver expects to see Audi roll
out its Magna-sourced “sport differential” in the S5 and Q5 to combat
understeer in its four-wheel-drive vehicles. This trick differential adds about
will be the first Audi vehicle in the U.S. with a longitudinal engine
layout to offer a dual-clutch transmission. Now known as S tronic, this
seven-speed sequential-manual will further improve performance and efficiency.
The supercharger will make the V-6 weigh about the same as the V-8 overall.
