Compared to its predecessor, the new Z4 is about 15 cm longer, but the wheelbase has grown just by few mm, this results in slightly longer overhangs which, together with the higher rear sholder – necessary to accomodate the hard-top – and the more conventional lighting units, contribute to give the new Z4 a less extreme look.

The range of available engines includes a 2.5 liter and two 3.0 liters engines – all 6-inline cylinders. BMW Power outputs are 204 hp (Z4 sDrive23i), 300 hp (BMW Z4 sDrive35i) and 255 hp in the BMW Z4 sDrive30i.
Both models have a manual six-speed gearbox, which can be replaced by a six-speed sport automatic on the Z4 sDrive30i and by a dual-clutch seven gears sport automatic transmission on the Z4 sDrive35i. Both sport automatic transmissions feature steering wheel-mounted paddle shifters.
The standard Dynamic Drive Control allows the driver to choose between three drivetrain and suspension settings at the touch of a button.
The car’s proportions are borne out by the long and low-slung engine compartment lid, short overhangs, the long wheelbase and large wheels as well as the low seating position near the rear axle.
The front view features a large, upright BMW kidney grille, wide air intake and the dual round headlights. All surfaces and lines, including the character lines on the hood, strive towards an imaginary target point on the road ahead.
The side view is dominated by the dynamic flow of the car’s shoulder line connecting the front and rear wheel arches and accentuating the stretched, athletic look of the Roadster.
Further characteristics are the extra-large hood extending far over the wheel arches, the black A-pillars, the gills at the side with their integrated LED direction indicators, as well as the slender rear fixtures with three-dimensional LED-fed rows of light.
The retractacle hardtop
The two-piece lightweight aluminum fully retractable hardtop opens and closes at the touch of a button within 20 seconds and allows for improved visibility.
Compared with the former model, the side windows are 40% larger, the see-through area in the rear window 52% larger, and all-round visibility increased by 14% over the previous generation.
The glass rear window in the hardtop is equipped with an electric defroster and the four side windows of the new BMW Z4 may be lowered individually. The higher roofline and larger door openings allow easier and more convenient access with the roof closed.
The compact packaging of the folding roof enables the Z4 Roadster to retain the characteristic, slender proportions of its predecessor.
The contoured surface to the left and right of the steering wheel incorporates the controls for the lights and air conditioning.
These elements are available trimmed in Satin Silver matte, Brushed Aluminum, and Ash Grain Wood, the respective color and trim variant also being used on the center console and door handle.
A fourth choice, Ivory White Nappa leather, is also available as part of the Exclusive Ivory White Leather Package, which includes sport seats and Anthracite wood trim.
An Extended Leather option (Z4 sDrive35i only) adds leather on the upper section of the instrument panel, the doorsills, the sun visors in Black leather as well as the leather-finish door closing handles in upholstery color on the passenger’s side.
The entire range of paintwork colors has nine color tones including Orion Silver metallic exclusive to the new Roadster.
