BMW Australia has ramped up the performance of its Z4 M40i roadster by announcing a 35kW increase to the power output of its 3.0-litre turbocharged six-cylinder petrol engine.
The increase means the Z4 M40i can now accelerate from 0-100km/h in just 4.1 seconds, an improvement of four tenths of a second over the previous model.
It also now aligns the Z4 M40i with fellow M Performance models M340i xDrive, X3 M40i and X4 M40i, which feature the 285kW version of the famed BMW TwinPower Turbo straight six powerplant.
In addition, the substantial update comes at no cost to the customer with the Z4 M40i remaining at $124,900*.
Announcement of the update further complements the BMW Z4 line-up, which launched in Australia earlier this year.
The Z4 combines focused driving performance with an extroverted exterior styling package designed by Australian Calvin Luk.
It also features an engaging and high quality interior matched with an electrically-operated soft top roof incorporating a lower centre of gravity than the previous generation Z4.
A 50:50 weight distribution, wider track, shorter wheelbase and rear-wheel-drive contribute to a highly sporty drive while evoking iconic characteristics of the car that inspired it – the legendary BMW Z8.
The entry point to the range, the Z4 sDrive20i, features a 2.0-litre turbocharged four- cylinder petrol engine that produces 145kW and 320Nm. This model can also be optioned with a six-speed manual transmission to add further enthusiast appeal.
The Z4 sDrive 20i, which is priced at $84,900 regardless of the transmission choice, achieves the standard sprint in 6.6 seconds.
The Z4 sDrive 30i, with a tuned version of the 2.0-litre turbocharged four-cylinder petrol engine, delivers 190kW and 400Nm, which enables a 0-100km/h time of 5.4 seconds.
That model is priced at $104,900.
