As part of an range of midlife changes to the BMW Z4 roadster, the automaker will add a new entry-level sDrive18i to the lineup. The car made its public debut at the Detroit Auto Show. The model is powered by a turbocharged 2.0-litre engine that delivers 154bhp and 177lb ft. This enables the six-speed manual sDrive18i to accelerate from zero to 62mph in 7.9sec and continue on to reach a top speed of 137mph.
The combined fuel economy can return 41.5mpg, with 159g/km in CO2 emissions. BMW also offers it with an optional eight-speed automatic. Meanwhile, the engines in the other Z4 models - sDrive20i, sDrive28i, sDrive35i and sDrive35is – will stay unchanged. The facelifted roadster gets only minor cosmetic changes. The most striking change is the revised LED headlights.
It comes with new alloy wheel options while it gets minor exterior trim detailing revisions. The other revisions include the optional Design Pure Traction styling pack, which gives the cabin some contrasting black and orange trim. In addition, the interior gets new gloss black trim for the air vent and iDrive surrounds as standard equipment.
For the sDrive28i models and above, leather trim is also standard. A Fineline Anthracite wood finish is offered as an option. On the other hand, the M Sport package (which consists of bespoke suspension settings, alloy wheels and exterior and interior trim) is available again. This time, the sDrive35is range-topper is offered with a more focused version of this pack.
The success of BMW’s modern-day Roadsters is attributed to a concept’s rigorous dedication. This process left its mark on the design and driving properties of each vehicle and is clearly identifiable in the new BMW Z4.
Its sweeping hood, low beltline, low-slung rear end, and long wheelbase all play a more uncompromising and vivid part in shaping its looks. Its low-seating position ahead of its rear axle gives you an intense experience of the lateral and longitudinal forces that work on the rear wheels. A sense of being a "part of the car" allows you to feel more attuned with the road.
Moreover, the Z4’s hardtop roof blends smoothly into its form and when it closes, it seals the seamlessly flowing roofline, while the large window surfaces optimize the all-round visibility as well as the sense of space inside. The two roof elements, once opened, are accommodated in a compact package in the trunk. The A-pillars, which are painted an understated black, highlight the new BMW Z4’s low-slung silhouette, especially when its roof is open.
Meanwhile, the BMW Individual hardtop, which is optional and is available in two contrasting colors – Titanium Silver metallic and Jet Black, is stunning when you close the roof. You can open the hardtop with a simple tap of a button even when the car is running at up to 25 mph in an automated process.
