BMW has revealed a host of changes to its model line-up for September, including efficient new versions of the Z4 and X1 and special edition versions of the 3-series Coupe and Convertible.
The Z4 gets a new twin-scroll turbocharged 2.0-litre four-cylinder petrol engine that puts out 181bhp in the sDrive20i and 242bhp in the sDrive28i. These models replace the sDrive23i and sDrive30i in the Z4 range respectively.
The sDrive20i can crack 0-62mph in 6.9sec and also return 41.5mpg combined, while emitting 159g/km of CO2. The sDrive28i has the same mpg and CO2 figures, but will get to 62mph in 5.6sec. Both models come with six-speed manual gearboxes as standard, with an eight-speed auto optional.
BMW claims the new X1 xDrive20d Efficient Dynamics will be the cleanest, most economical X product ever. It gets a 163bhp 2.0-litre four-cylinder turbodiesel engine that helps the X1 return 62.8mpg combined and emit 119g/km of CO2.
The X1 ED features BMW’s now familiar Efficient Dynamics technology, including stop-start, a brake energy recuperation system, a gear shift indicator, low rolling resistance tyres and lightweight alloys.
The X1 xDrive20d Efficient Dynamics will cost from £25,715 when sales start in September.
The BMW 3-series Coupe and Convertible Sport Plus Editions are two further additions to the BMW range. These M Sport-based models get 19-inch double-spoke lightweight alloys, a new rear bumper with integrated diffuser and Jet Black mirror casings. Coupe Sport Plus Editions also get the M3’s lip spoiler.
