Every now and again, we get invites to quick test-drive events, and for the most part we simply ignore them. But when BMW invited us to test out the new 435i M Sport along with its nearest competitor, the 2014 Audi S5 , I would have been nuts to say "no." In one corner is the newest Bimmer with 300 horses coming from its TwinPower Turbo I-6 and all the cool little M Sport bits — brakes, wheels, suspension, etc. In the other corner is the tried-and-true Audi S5 with 333 horses and 325 pound-feet of torque.
This battle of German midsize coupes also includes a battle of power-generating philosophies. From Bimmer you have the new-age twin-scroll turbocharging system and from Audi you have the old, faithful supercharger. Many years ago there was no contest between the two, because the supercharger had no lag, while older turbos had serious lag issues, resulting in slower initial launches while the exhaust gases get the turbo spooling. The introduction of twin-scroll turbocharging and BMW’s perfection of the technology has rendered this a non-issue.
Both the 435i and the S5 are outstanding rigs and do the job of combining performance and luxury well without pushing the bounds of comfort like the wild RS5 and M4 . But which one is the victor in this quick, five-mile-long test in city traffic?
