A side by side comparison between the Audi TT Roadster and the BMW Z4 shows how Ingolstadt’s latest open-top model stacks up against the venerable Bavarian model. The third generation TT Roadster was unveiled just a few days ago so it’s certainly the fresher model in this comparison as the second-gen Z4 came out towards the end of 2008 and was facelifted early 2013.
The 2015 Audi TT Roadster come with a soft top which is now 3 kg lighter in comparison to the previous generation thanks to more aluminum and magnesium in its construction. It will be offered initially with only three engines: 2.0 TFSI with 230 HP, a 2.0 TDI with 184 HP and a more potent 2.0 TFSI with 310 HP in the TT S. The latter will do 0-62 mph (0-100 km/h) in 4.9 seconds before topping out at an electronically-limited 155 mph (250 km/h).
On the other hand, the BMW Z4 can be had with a much wider engine array, kicking off with the sDrive18i that has a 2.0-liter turbo with 156 HP. There’s also an sDrive20i with the same engine but uprated to 184 HP while in the sDrive28i the engine is bumped to 245 HP. An sDrive35i with a 3.0-liter six-cylinder twin-turbo packs 306 HP while sitting on top of the range is the sDrive35is with 340 HP.
