Audi A5 Sheds Two Cylinders in Midcycle Refresh

As part of a midcycle refresh for its A5 coupe and convertible range, Audi announced Wednesday that the high-performance S5 model would lose its normally aspirated 354-horsepower V-8 in a trade for the brand’s 333-horsepower supercharged V-6, similar to the one used in the S4 sedan. The 6, Audi says, is about 20 percent more fuel-efficient than the outgoing 8.

The 2012 RS5, however, is expected to retain a 4.2-liter V-8 when it goes on sale in North America next year.

The 2013 models, which are to be shown at the Frankfurt auto show in September, feature new grilles, front fascias and headlamp designs, and a shift from hydraulic steering to electric power. The basic A5 coupe will carry on with the workhorse VW Group turbocharged 2-liter in-line 4 that makes 211 horsepower and 258 pound feet of torque. Subtle cosmetic tweaks include new steering wheel designs, a new selector for automatic transmissions and a revised finish for the instrument panel and center console.
