When the BMW Z4 sDrive35is was announced it was remarkable how many of the car’s key stats were on par with the Audi TT RS. Well now we can add another one—price. With a starting list price of $129,900 the top range Z4 is a few grand cheaper than the TT RS. In regards to power and torque, both cars offer 250kW and 450Nm.
The Z4, though, includes a few party tricks in its kit to help it trump the TT RS. On paper, anyway. The sDrive35is can momentarily utlilise an overboost function on the 3.0 litre straight six twin turbo engine to push torque to a peak figure of 500Nm. While Audi is known for their S tronic double clutch gearbox it is an optional extra on the TT RS. With BMW’s new hero roadster a 7-speed DCT is all yours with the standard asking price.
Making the most of that nifty DCT is a launch control feature which should make it a doddle to perform repeated sprints to 100km/h in BMW’s claim of 4.8 seconds.
Helping to differentiate the most expensive Z4 in the range from its cheaper models is a tiny little “s” at the end of the model designation. Seeing as most punters will probably miss that you best point out the aluminium wing mirrors. Y’know, just like on the TT RS. Also, there is a more aggressive front spoiler, part of a more comprehensive M Sport Package.
After driving the Z4 range earlier this year AUSmotive is pretty sure the chassis can handle the extra kilowatts on offer from that little s. Of course, BMW has no doubts that it can, and you can read their spiel after the jump.
