Following the unveiling of the all-new BMW Z4 M40i First Edition Roadster, BMW unveils the 2019 BMW Z4 sDrive30i Roadster, which arrive in March of 2019. Agility, performance and precise handling have always been top priorities for the Z4 family but the new two-seater body, powertrain and chassis have received the greatest amount of development work to make sure the new Z4 Roadster arrives with a genuine sports car performance pedigree.
The all-new BMW Z4 Roadster has gone through a thoroughly complete training program and features two new powerful TwinPower Turbocharged engines and brand new front and rear suspensions developed specifically for the Roadster. The rigid body structure, chassis mounting points, along with the intelligent lightweight design and optimized aerodynamic properties deliver the perfect platform to provide the driver with a Roadster capable of tackling the most challenging tracks while at the same time providing increased levels of comfort for top down cruising along the coast.
The new 2019 BMW Z4 Roadster has a low-slung, sporty and athletic appearance when viewed from any angle. The proportions have grown in every area over its predecessor: 3.3 inches longer, 2.9 inches wider and 0.5 inches taller. The wheelbase has been shortened by 1.0 inch which, combined with the notably wider tracks (+3.86 inches in front and +2.45 inches in rear) and a perfect 50:50 weight distribution, all contribute to the much enhanced vehicle agility.
To complement the new chassis’ increased capabilities, the new 2019 BMW Z4 Roadster arrives with a new, more powerful 2.0 liter four-cylinder TwinPower Turbocharged motor featuring an increase of 15 hp and an impressive 35 lb-ft of torque over its predecessor. The updated BMW engine package include a High Precision Injection system whose maximum pressure has been increased to 350 bar / 5,076 psi. The TwinScroll turbocharged engine under the hood of the new BMW Z4 sDrive30i delivers an output of 255 hp between 5,000 and 6,500 rpm, with peak torque of 295 lb-ft. available from 1,550 up to 4,400 rpm. The result is a 0 to 60 mph sprint time of 5.2 seconds.
For those seeking even more exhilarating performance, the BMW Z4 M40i Roadster 3.0-liter six-cylinder in-line engine delivers instantaneous response, an appetite for revs and smoothness while offering an increase of 47 hp over its predecessor. The new 6-cylinder engine standout features include a water-cooled exhaust manifold integrated into the cylinder head, quicker TwinScroll turbocharger response and direct injection technology which now works at increased maximum pressure of 350 bar / 5,076 psi. Drivers have 382 hp at their disposal between 5,000 and 6,500 rpm, plus 369 lb-ft. of peak torque from 1,600 to 4,500 rpm. The BMW Z4 M40i Roadster sprints from 0 to 60 mph in just 3.9 seconds.
Both models equipped with a standard eight-speed Steptronic Sport transmission with shift paddles on the steering wheel. Besides a wider ratio spread, the latest version of the automatic transmission offers even sportier gear shifts. The shorter ratios for the transmission lower gears improve acceleration and the unit’s improved internals allow it to operate more efficiently. The transmission features Launch Control for accelerating hard from a standing start with maximum traction. The eight-speed Steptronic Sport transmission fitted in the BMW Z4 M40i has been configured with M-specific shift characteristics to complement the straight-six engine power delivery.
The Adaptive M Sport suspension, M Sport brakes and M Sport differential, standard on the Z4 M40i Roadster and optional on the Z4 sDrive30i, raise the car’s already impressive handling bar to even greater heights. With these chassis systems on board, the differences in the car’s responses between the COMFORT, SPORT and SPORT+ modes, selected with the Driving Experience Control switch, are particularly noticeable. Featuring a 10 mm lower ride height, the Adaptive M Sport suspension includes electronically controlled dampers, which offer both comfortable and more aggressive ride and handling dynamics. The electronically controlled M Sport rear differential gives the handling of the 2019 BMW Z4 an even sharper sporting edge. An electric motor generates a locking effect in the differential that equalizes torque distribution between the inside and outside rear wheels when cornering, making it possible to power out of bends with greater momentum. The active differential lock also works effectively in reducing both understeer and oversteer.

A number of signature details form the defining features of the 2019 BMW Z4 Roadster. The combination of very notable lines and a clean-cut surface design create a very distinctive take on sporting roadster. A sculpted front end with large air intakes, a low, broad BMW kidney grill and headlights positioned at the outer edges showcase BMW’s new design direction. The new mesh-design BMW kidney grill combines a track-inspired honeycomb pattern with a three-dimensional structure, whose elements have a vertical arrangement reminiscent of traditional BMW kidney grill bars. The design of the headlight units are a first for the brand, with the two light sources positioned one above the other. The vertical design is cut off at the top by a diagonal accent strip with integral direction indicator. The new BMW Z4 Roadster is equipped with LED headlights as standard and Adaptive LED headlights available as an option.
The long hood with arrow-shaped contour lines directed at the kidney grill straddles the wheel arches in a characteristic of classical sports cars of the past. An upper character line runs from the bottom of the hood to the tail lights. A second, lower character line emerges from the large air vents behind the front wheel arches. This interplay of surfaces mimics the flow of air sweeping along the new Z4.
The trunk lid’s integrated spoiler and the slender, horizontally arranged light assemblies in the BMW brand’s customary L-shape help to give the tail of the new BMW Z4 Roadster a wide, road-hugging appearance. The rear end’s powerful look is strengthened by the side surrounds and the trapezoidal exhaust tailpipes flanking the eye-catching diffuser.

The highly advanced nature of the 2019 BMW Z4 is further underlined by the class-leading variety of offered driver assistance systems. Forward Collision Warning and the Daytime Pedestrian Detection with City Braking function come as standard, as does the Lane Departure Warning system. The list of options includes the Driving Assistance Package featuring Active Cruise Control with Stop & Go function, the Speed Limit Info system, the Active Blind Spot Detection, plus Rear Collision Protection and Cross-Traffic Alert.
The range of functions also includes the Back-up Assistant, which offers the highly convenient option of automated reversing in situations where there is little margin for error or the driver does not have a clear view. To do this, the system stores the steering movements for the section of road the car has just driven forward. It then traces these last forward movements when reversing and keeps the car on exactly the same path for a distance of up to 150 feet. All the driver has to do is operate the accelerator and brake pedals and keep an eye on the area around the car.
The 2019 BMW 330i arrives in March 2019 with a starting price of $49,700 plus $995 destination and handling.
