Autoweek archives: BMW introduces the revvy 325is

This selection from the Autoweek archives comes from longtime contributor Phil Berg back in September 1987. Berg examines the BMW 325is, with its new, free-revving, 2.5-liter inline six-cylinder, making BMW’s small sedan an even more desirable ride.

BMW Z4 sDrive 35is (2009) at Detroit motor show 2010

These are the first official pictures of the new high-performance BMW Z4 sDrive 35is, unveiled today at the Detroit motor show. A bit of a mouthful (that's BMW's new nomenclature for you), but it's essentially the fastest, hardest Z4 to date since the recently departed M roadster curled over and died.The Z4 sDrive 35is uses Munich's existing 3.0-litre twin-turbo straight six, tweaked to produce 335bhp and 332lb ft of the twisty stuff all the way from 1400-4500rpm. That's one flat torque curve, and a 29bhp jump over the regular sDrive35i.

But after speculating on what Land Rover would call their range topping Sport – R, RS, SO or something else – that turned in to ‘something else’ with the arrival of a new JLR moniker – SVR.
