2015 BMW Z4 Vehicle Overview
Comfort & Convenience
The behind-the-seat storage bench comes standard. Additional storage space behind the seats is perfect for items like briefcases or handbags. And optional through-load storage for longer items like skis and golf clubs means your trunk space will never limit your extracurricular activities.
Premium Interior Details
The driver gets the royal treatment with a refined driver-oriented interior and special accent surfaces like Satin Silver (30i), Brushed Aluminum (35i), or optional Ash Grain Wood trim. Choose from Black, Canberra Beige, or Coral Red leather. Or select the optional Exclusive Ivory White Leather Package with Anthracite wood trim, and Sport Seats covered in luxurious Nappa Leather.
Retractable Hardtop Roof
Introducing the first-ever retractable hardtop in BMW Roadster history. Closed, it becomes an integrated part of the exterior design. Open it with a touch of a button and, in 20 seconds, it blends discreetly with the elegant look of the rear. This revolutionary feature increases ease of entry for both you and your passenger and provides 40% more glass than previous models, offering an enhanced sense of space and improved visibility.
True Roadster Proportions
Remaining true to its roadster heritage, the Z4 features a long engine hood, lower belt and trunk line and low seating position. Inside you'll find more glass area, providing lighter and greater visibility than a hardtop for a relax-and-enjoy-the-ride feel.
Extensive Music and Communications System
Create a new soundtrack for every drive by choosing from thousands of your own songs or from an extensive range of digital radio stations. Your iPhone®, iPod®, or other MP3 device easily connects to the optional iPod and USB adaptor for stereo playback. Skip tracks, access up to five playlists, store music on your vehicle’s optional hard drive, and adjust the volume through the car’s steering wheel controls and/or iDrive controller to allow you to keep your eyes where they belong - on the road. Vary your music with the HD Radio® or Sirius XM™ Satellite Radio options. More than 1,300 AM and FM stations have been upgraded to HD radio technology with more than 600 of the FM stations also offering "multicast" channels. Song artists and titles are shown on your display screen, so you’ll always know exactly what your favorite new tune is. Sirius XM™ Satellite Radio delivers 60 commercial-free music stations and more than 40 news, sports and entertainment stations, ensuring you’ll find something that suits your mood. A one-year subscription is included.
The iDrive system
The redesigned BMW iDrive with optional navigation is our most intuitive entertainment and navigation system yet. Full-screen maps display your destination directions and traffic information. And, if you are a safety plan subscriber with the optional BMW Assist™ + Bluetooth® System, it will even redirect you in the event of heavy congestion. Developed to operate by touch to keep your eyes on the road, the new system features a larger 8.8-inch display screen with high-resolution graphics, an extended range of functions, and an optimized menu structure with a more intuitive interface.
Performance & Efficiency
BMW Approved Cold Weather Tires
BMW Approved Cold Weather Tires have been specifically formulated to combat the reduction in traction that occurs when the temperatures drop below 45°F. An optimized balance between physics and chemistry provides the superb grip that's required to keep your BMW performing like the Ultimate Driving Machine® on all adverse road conditions in virtually all weather.
Small is the next big idea in engines - namely, BMW's mighty inline 4-cylinder TwinPower Turbo. Displacing just 2.0 liters, this 240-hp marvel generates 260 lb-ft of torque at just 1250 rpm, for potent thrust that kicks in right from the start and continues all the way up to 4800 rpm. Lightweight and smooth-running, it incorporates BMW's award-winning High Precision Direct Injection, Valvetronic and Double VANOS technologies. And its dynamic performance is equaled by spectacular fuel efficiency, which is estimated to take you 20 percent further on every gallon of gas than did its 6-cylinder predecessor.
6-Speed Transmission (Optional STEPTRONIC)
With a standard 6-speed transmission and an optional 6-speed STEPTRONIC automatic transmission available in the Z4 sDrive30i, this roadster was made to take on the curviest roads you can find.
Multi-link Rear Suspension
Thanks to a lightweight chassis with an aluminum front axle and multilink rear suspension, the Z4 brings you a whole new level of comfort, reduced fuel consumption, and impressive handling. And, the optional Adaptive M Sport Suspension allows you to choose between Normal or Sport modes for even greater driving dynamics. The difference? Normal mode utilizes the suspension to lessen the impact of the road, while more power assist is directed to the steering, giving you better maneuverability. Sport mode, on the other hand, makes for more rigid suspension and offers a quicker throttle response, tighter shift points and more precise control.
You'll notice the power of the engine when you’re behind the wheel, but what you might not notice immediately is how efficient that inline four-cylinder really is. Thanks to BMW's engine management and its lightweight construction, the Z4 has better fuel efficiency and fewer emissions than the competition. The Z4 achieves this impressive level of efficiency through a series of innovative technologies. For the Z4 sDrive30i, Double VANOS maximizes engine response, efficiency, and emission control by electronically controlling valve timing for both intake and exhaust camshafts. Our patented Valvetronic technology, found in both vehicles, enables the engine to breathe more easily, allowing for increased power output while also optimizing fuel efficiency.
Safety & Security
Get better stability and control on tough road conditions through a system that continually processes data from the anti-locking wheel-speed sensors. When a rear wheel begins to lose traction, the engine’s electronic throttle and ignition timing are modified to reduce torque. Part of Dynamic Stability Control, All-Season Traction can act on each rear brake individually or simultaneously, as needed, to help bring wheelspin under control.
Our enhanced braking system does more than just brake. In rain, the automatic windshield wipers trigger the brake-drying feature, which presses the brake pads to the rotors to dry them. Quickly taking your foot off the accelerator triggers Brake Standby, preparing the brakes for emergency stopping. And, if you're on a downhill slope or repeatedly engage the brake, Brake Fade Compensation helps to keep consistent brake pressure when your brakes heat up.
Rollover Safety System
The rollover safety system features two steel rollbars behind the headrests and a rollbar of high-strength tubular steel integrated into the roof for maximum safety.
There's no good place for a flat tire, but with run-flat technology, you get up to 150 miles of driving at 50 miles per hour, so you can drive yourself safely to a BMW center for a replacement. The self-supporting tires come with integrated reinforcements, allowing punctured tires to maintain their shape and full use.*
2014 BMW Z4 Vehicle Overview
What's New for 2014
For 2014, the BMW Z4 receives a handful of minor changes. Among them are restyled fender-mounted signal repeaters and a few new options packages including the Hyper Orange package and the Technology package.
A roadster used to be a small, two-seat convertible with adequate power, sporty handling and minimal comfort features. Heck, the really old ones didn't even have roll-down side windows. But what they lacked in frills, they made up for with an engaging driving experience and affordable pricing. Most modern roadsters are different animals entirely, as they're not exactly diminutive, and they boast powerful engines, a wide array of luxury features and, all too often, big price tags. The 2014 BMW Z4 stands proud among the new-era, premium-brand roadsters.
But just because you can get leather upholstery and a heated steering wheel in the Z4 doesn't mean this Bimmer has forgotten how to have fun. It's a BMW, so you'd expect it to be a capable companion on curvy two-lane roads, and it is. Plus, there's plenty of thrust with either of the available turbocharged engines, one a fuel-sipping inline four-cylinder and the other a broad-shouldered inline-6.
Furthermore, the Z4's roomy seating and ample creature comforts make it pretty hospitable for commuting and even road trips. Adding an extra measure of serenity and security is the retractable hardtop. Even the trunk is generously sized, at least when the roof is raised.
Body Styles, Trim Levels, and Options
The 2014 BMW Z4 is a two-seat convertible with a retractable hardtop roof. There are three versions that correspond to engine size: sDrive28i, sDrive35i and sDrive35is.
The 28i comes standard with 17-inch wheels, automatic and adaptive bi-xenon headlights, LED running lights, automatic wipers, heated mirrors, keyless ignition/entry, cruise control, dual-zone automatic climate control, eight-way power seats with four-way lumbar adjustment and driver memory functions, a leather-wrapped tilt-and-telescoping steering wheel, leatherette premium vinyl upholstery, auto-dimming mirrors, basic BMW Assist service, Bluetooth phone connectivity and a sound system that includes a CD player, HD radio, an auxiliary audio jack and an iPod/USB audio interface.
Besides its bigger engine, the 35i gets 18-inch wheels, sport seats (with adjustable side bolsters and thigh support) and sun-reflective leather upholstery. These items are optional on the 28i.
The 35is adds an even more powerful engine, unique styling cues, a lowered suspension with adaptive dampers, an upgraded audio system and a sport steering wheel.
Each Z4 offers the following optional packages. The Cold Weather package adds heated front seats, a heated steering wheel and retractable headlight washers. The M Sport package adds an adaptive M-tuned suspension, lightweight 18-inch wheels, an increased top speed limiter, an aerodynamic body kit, a thicker sport steering wheel and special interior trim. The Technology package features a navigation system, 12GB of music storage, voice commands, enhanced BMW Assist, enhanced Bluetooth/USB functions and smartphone apps/integration.
Color themed packages are also available. The Canyon Brown package features like-named leather seating, the power sport seats and anthracite wood accents. The Hyper Orange package allows one to select a Valencia Orange exterior color (not mandatory, however) and features a black and orange interior scheme. It also includes faux suede on the headliner, seats and door panels as well as unique "metal weave" cabin accents.
Available for the 28i is a Sport package (18-inch wheels, power sport seats, adaptive M-tuned suspension and an increased top speed limiter). Both the 28i and 35i can be had with a Premium Sound package that includes the 35is's upgraded audio system along with satellite radio.
Stand-alone options include different wheels, front and rear parking sensors, automatic high beams, heated seats and satellite radio.
Powertrains and Performance
The 2014 BMW Z4 sDrive28i features a 2.0-liter turbocharged four-cylinder with 240 horsepower and 260 pound-feet of torque. Rear-wheel drive is standard, and you can get either a six-speed manual or an eight-speed automatic at no extra cost. Manual-equipped cars include an automatic stop-start function that turns off the engine when the car is stopped to improve efficiency. In Edmunds performance testing, a manual-equipped Z4 28i went from zero to 60 mph in 5.8 seconds, similar to what the V6-powered Mercedes SLK350 runs. EPA-estimated fuel economy is 27 mpg combined (22 city/34 highway) with the manual, with the automatic coming in at 26 combined (22 city/33 highway).
The Z4 sDrive35i gets a 3.0-liter turbocharged six-cylinder that produces 300 hp and 300 lb-ft of torque. It gets a standard six-speed manual (no auto stop-start), and a seven-speed automated manual transmission (known as DCT) is an extra-cost option. With the manual, this Z4 hit 60 mph in 5.2 seconds.
The Z4 sDrive35is gets a more powerful version of the 3.0-liter turbo-6 good for 335 hp and 332 lb-ft of torque. At full throttle, an overboost function increases torque to 369 lb-ft. The DCT is the only available transmission. In Edmunds testing, the 35is went from zero to 60 in 5 seconds flat. Fuel economy ratings are 20 combined (17 city/24 highway).
Every BMW Z4 comes standard with antilock brakes, stability and traction control and side airbags. The antilock brakes also integrate several features designed to improve braking performance, such as periodically wiping the brake rotors dry when the windshield wipers are in use and snugging the brake pads against the rotors if the driver abruptly lifts off the throttle. The BMW Assist eCall system is standard and includes an emergency assistance button and automatic crash notification. This system can be upgraded to include BMW Assist Remote Services that include stolen vehicle recovery and remote door unlock.
In Edmunds brake testing, the 28i came to a stop from 60 mph in an outstanding 103 feet. The other two models were essentially identical.
Interior Design and Special Features
The 2014 BMW Z4's cabin is sleek and upscale. High-quality materials abound and combine with diverse shapes to create an undeniably premium environment. Several two-tone color choices add some further pizzazz. Thoughtful touches include secondary knee-level air vents and a small cargo shelf behind the seats.
The Z4 is also arguably the most practical two-passenger sports car on the market. Legroom is plentiful, which is something you don't hear often about small convertibles. Visibility is also unmatched thanks to large rear quarter windows that eliminate the typical blind spots in most roadsters. With the hardtop roof raised, the trunk provides a generous 8 cubic feet and is capable of holding two sets of golf clubs and a carry-on suitcase. You'll have to ditch those clubs when you lower the two-piece hardtop, but the suitcase can remain, which is more than you can say for some other hardtop convertibles. There's also an available trunk pass-through that can accommodate longer items.
