New BMW Z4 Tit for tat on dimensions

The BMW Z4 will be available with a larger, five-strong line-up of petrol engines from launch, and customers will be able to choose from three four-cylinder and two six-cylinder powerplants. Their most significant shared feature is BMW TwinPower Turbo technology, which ensures an exceptionally effective balance between driving pleasure and fuel consumption throughout the output range. In addition, all four-cylinder variants of the new BMW Z4 already meet – as standard – the stipulations of the EU6 exhaust emissions standard due to come into force in 2014.

The BMW Z4 sDrive18i takes to the stage as the new entry-level model. It is powered by a 2.0-litre engine with BMW TwinPower Turbo technology which develops maximum output of 115 kW/156 hp at 5,000 rpm. The new variant of the four-cylinder unit delivers peak torque of 240 Newton metres (177 lb-ft) between 1,250 and 4,400 rpm. The BMW Z4 sDrive18i is fitted as standard with a six-speed manual gearbox, but an eight-speed sports automatic can also be ordered as an option. The new model accelerates from 0 to 100 km/h (62 mph) in 7.9 seconds (automatic: 8.1 seconds) and hits a top speed of 221 km/h / 137 mph (220 km/h / 136.5 mph). Average fuel consumption for the BMW Z4 sDrive18i in the EU test cycle is 6.8 litres per 100 kilometres (41.5 mpg imp) with both the manual and automatic gearbox. CO2 emissions stand at 159 grams per kilometre.

The BMW TwinPower Turbo technology package for the new BMW Z4 sDrive18i includes twin-scroll turbocharging, High Precision Direct Petrol Injection, VALVETRONIC fully variable valve control and Double-Vanos continuously variable camshaft control. An identical version of this technology package is also used in the engines – likewise 2.0-litre units – under the bonnet of the BMW Z4 sDrive20i and BMW Z4 sDrive28i. These engines can also be ordered with an eight-speed sports automatic gearbox with shift paddles on the steering wheel as an alternative to the standard-fitted six-speed manual. The automatic has been optimised to deliver even better acceleration from 0 to 100 km/h (62 mph).

The existing engine variants – the sDrive20i, sDrive28i, sDrive35i and sDrive35is – retain their places in the range.
