C&D reviews the A5 space frame - shaves 500lbs off
http://www.caranddriver.com/reviews/...rototype_drive
They shaved 500 lbs off the EU spec 3.2 V6 A5 by using the space frame, lots more aluminum and paired the lighter car with the 2.0T engine. then they dialed the 2.0T in Tq to match the same output as the V6:
The resulsts?
.3 seconds faster than the V6, and .7 faster than the stock A5 with the 2.0T.

Audi let us compare a stock A5 3.2 FSI, equipped with the 265-hp V-6, against the lightweight concept with the 2.0-liter engine dialed back from 258 pound-feet of torque to deliver the same 243 as the V-6.
The resulsts?
...the A5 V-6 ran from zero to 60 mph in 5.8 seconds, so we expect the lightweight concept to hit 60 mph in 5.5 seconds, a 0.7-second improvement over a standard A5 2.0T.

Tech like that IMO is another decade out for anything lower than A6.
And image the insurance cost to cover aluminum frame cars.
BTW, is there any aluminum panels on the S4? They seem to say standard A5 has aluminum panels in the front (hood and quarter panels).
