2012 BMW Z4 sDrive28i. The car is not an entirely new model, it received BMW’s brand new 2.0 liter twin-scroll turbocharged petrol engine with a nice power of 245PS (180 kW) and a train-pulling 350Nm (260 lb-ft) of torque. This new engine replaces the well-known 3.0 liter six-cylinder petrol in 25i and 30i.
2012 Z4 sDrive28i accelerates from 0 to 100 km/h in 5.7 seconds and still returns a nice 41.5 mpg on combined cycle with emissions below 160 g/km. This is possible thanks to a number of modern technology – Double-VANOS variable camshaft timing and VALVETRONIC variable valve opening. The top speed of the roadster is 250 km/h (155 mph), doesn’t matter whether the roof is up or down. (more…)
