The all-new 2019 BMW Z4 Roadster
Agility, performance and precise handling have always been top priorities for the Z4 family but the new two-seater’s 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.
If the chassis is the legs and muscles of a top performing athlete then the engines are the heart and lungs. 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.
Z4 sDrive30i: More power from the new four-cylinder engine.
To complement the new chassis’ increased capabilities, the new BMW Z4 Roadster arrives in 2019 first 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.
Z4 M40i: BMW M Performance model with straight-six engine.
Eight-speed Steptronic Sport transmission
Both models of the new BMW Z4 Roadster, sDrive30i and M40i, come 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’s 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’s power delivery.
New chassis: increased agility and comfort.
Another standard feature is the sport steering with variable power assist and ratio. This particular version of the power steering system is designed to promote not just straight-line stability in the new BMW Z4 Roadster, but also provide precise feedback during cornering and effortless low-speed maneuvering.
The car’s impressively sporty handling characteristics are aided by powerful lightweight braking and Dynamic Stability Control (DSC) systems, whose wealth of features includes the Anti-lock Braking System (ABS), Dynamic Traction Control (DTC), Cornering Brake Control (CBC), and Dynamic Brake Control (DBC). The standard Performance Control function gives the new BMW Z4 Roadster even nimbler handling by varying the distribution of drive torque to the rear wheels according to the situation at hand.
M Performance model drivetrain
The standard 18-inch light-alloy wheels and optional 19-inch items are all shod with mixed-size tires. The wider rear tires’ increased potential for directional control was factored into the chassis tuning for all variants of the all-new Z4 Roadster.
The new BMW Z4 Roadster isn’t just about classical roadster proportions and spirited driving – it is imbued with state-of-the-art features to pamper both driver and passenger alike. The options list contains a myriad of ways to customize the all-new BMW Z4 Roadster to suit the owner’s personal style.
The array of cutting-edge driver assistance systems available for the Z4 Roadster is unrivalled in this segment. They are designed to optimize specific aspects of comfort and safety and relieve the strain on the driver during both long-distance journeys and in city traffic. The list of options includes Active Cruise Control with Stop & Go function, the Lane Change and Lane Departure Warning systems, as well as a Parking Assistant including Back-Up Assistant. The new BMW Z4 is also the first Roadster to be made available with an optional BMW Head-Up Display.
Exterior: a new design language.
A number of signature details form the defining features of the all-new 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 “clamshell” style 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.
Individuality: colors and packages
There is a choice of eight colors for the exterior, including Frozen Grey for M Sport models. The interior choices include both SensaTec and Vernasca leather with a special Vernasca/Alcantara upholstery available for M Sport vehicles. The soft-top roof comes in Black as standard and Anthracite with silver effect as an option. It is electrically operated and can be opened or closed in the space of ten seconds, at speeds up to 31 mph.
The Z4 sDrive30i arrives with Sport Line as standard. Further performance enhancements for this model include the optional M Sport or Track Handling packages. The highlights of the M Sport package include a three-section air intake for the front apron, prominent side skirt contouring, a rear apron with highly distinctive side surrounds, 19-inch M light-alloy wheels, M Sport or Adaptive M suspension, an M Sport steering wheel and Active Driving Assistant. The Track Handling package includes M Sport brakes, Adaptive M suspension and the M Sport differential.
Climate Control and audio: a personal sense of well-being
The optional ambient lighting brings a soothing mood to the cabin. LED fiber-optic lighting in the instrument panel accent strips provide indirect illumination of the center console’s edging. The color and brightness of the lighting effect are adjusted in the iDrive menu. The standard hi-fi audio system offers a total of ten speakers and output of 205 watts. For a more impressive aural experience, there is the Harman Kardon surround sound system complete with digital amplifier, 12 speakers and 464-watts.
Model-specific seats and over 50 per cent more trunk capacity.
The new BMW Z4 comes standard with electric sports seats featuring integral head rests. The seat rails have been extended in length by 0.9 inches over those in the predecessor model, allowing the seats to be adjusted over a greater range. The optional M sports seats include electro-pneumatic backrest width adjustment to optimize lateral support through high-speed corners.
The practicality of the new BMW Z4 Roadster has been increased by a storage space behind the seats with a retaining net, large cupholders under the center armrest cover (which folds open in two sections) and roomy door pockets. The trunk capacity is 9.9 cu. ft. (with the soft-top open or closed), an increase of more than 50 percent compared to the previous Z4. An optional trunk through-loading system extends the possibilities for handling longer items during everyday use and when going away on trips.
BMW Personal Co-Pilot: Innovative systems to help drivers
The highly advanced nature of the new 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.
BMW Live Cockpit Professional: Seventh generation of the BMW iDrive
The seventh incarnation of iDrive, which runs the latest BMW Operating System, has a cutting-edge, fully digital design and is geared even more closely to the driver’s needs by allowing him or her to customize the system to his or her own preference with customizable widgets of information. This new level of personalization is then stored in the BMW Cloud and can follow the customer to other BMW vehicles. Various information from categories such as driving, entertainment, navigation, connectivity, and the vehicle info itself, can be selected in nearly any combination in any of four layouts on the Center Display. Multiple pages can be created and easily accessed with a simple swipe across the screen with a finger.
To maximize the capabilities of the large 12.3” digital instrument cluster, the traditional circular gauges have been finessed into an all-new design pushing the speedometer and tachometer gauges to the outer edges of the display as geometric bands. This new design opens space in the middle for routing and navigation, if desired. Information from the center display can also be shown within the tachometer. Additionally, the chosen driving mode will determine the visual display style.
Other elements of the BMW Live Cockpit Professional are the Navigation Professional system, a hard-drive-based multimedia system with 20 GB of memory and two USB ports, plus Bluetooth and Apple CarPlay interfaces. The driver can be automatically identified and personal settings activated either using the traditional vehicle key or by downloading the driver’s personal settings the BMW Cloud.
Drivers can enjoy the full benefits of the car’s intelligent connectivity capabilities through vehicle apps such as news, weather, office and online search. Other capabilities include Intelligent Emergency Call – which automatically summons swift assistance in an emergency – and regular updates for the navigation system’s maps.
The Connected Package Professional includes Remote Services, Concierge Services, On-street Parking Information, and Real Time Traffic Information and is standard on the all-new Z4 for a duration of 4 years. This connectivity suite will allow for easy integration and adaptation of new technology over time. Customers can continue to download various new digital services individually as they become available or renew existing services via the ConnectedDrive Store.
BMW Connected: digital services for individual mobility
At the heart of it all is the Open Mobility Cloud, which allows the app to connect the car with the customer’s digital devices. These could include the iPhone and Apple Watch, smartphones and smartwatches running the Android operating system, Alexa-compatible smart devices and Google Home. For instance, the BMW Connected app can import appointments and addresses from the customer’s calendar entries straight into the navigation system to begin route guidance. The system calculates the optimum departure time based on real-time traffic information and notifies the driver with a message on their smartphone when it is time to leave. As the vehicle is linked up via the Open Mobility Cloud, it is able to access the calculated route directly when the navigation system starts up.
Always up to date thanks to Remote Software Upgrade.
The Z4 is Remote Software Upgrade capable. This feature keeps the vehicle up to date with the latest software. All updates can be loaded over the air, similar to smartphones. The upgrades can be loaded onto a smartphone via the BMW Connected app when connected to a Wi-Fi network or imported directly via the BMW’s built-in SIM card.
