Edmunds' Expert Review

The Z4's body lines may not be as sexy as those of the Mercedes SLK, but for the money, you'd be hard-pressed to find a more entertaining luxury roadster.

Vehicle overview

The Z4 is the successor to the much loved Z3, which saw unfaltering popularity among young and old upon its introduction in 1996. Its successor is only offered as a roadster and has dropped its predecessor's sleek, scantily clad version of BMW's corporate styling in favor of a "flame surfaced" exterior design. The styling is certainly a break with tradition, but even if you don't like the car's sheet metal, there is plenty to appreciate on the Z4. In terms of overall length and width, the Z4 is slightly bigger than the Z3. The body is stiffer, and measures were taken to reduce weight without sacrificing rigidity. Handling is sharper than before, and the electrically assisted steering rack delivers solid road feel. For power, the Z4 offers either a 184-horsepower, 2.5-liter straight six or a 225-hp, 3.0-liter straight six. For transmissions, there is a five-speed manual (standard on the 2.5), a six-speed manual (standard on the 3.0), a five-speed automatic or, as previously seen on the M3, a six-speed Sequential Manual Gearbox (SMG). The power-operated top (which can go up or down in 15 seconds) has a special folding mechanism that allows extra storage space. BMW claims that the trunk can hold two golf bags. When the top is opened, the front-most section of the roof folds over the soft top like a cover and rests flush on the body when fastened in position, thereby eliminating the need for a tonneau cover. The rear window is glass rather than plastic, and a wind deflector and hardtop are also available. Sport Package-equipped roadsters feature Dynamic Drive Control (DDC) technology, which delivers quicker throttle and steering response at the press of a button. Although we still can't warm up to the exterior styling, in just about every other respect, the Z4 is a seriously capable driver's car -- and one of our favorite roadsters in this price range. If you've got $35,000 to $45,000 to spend on a two-seater, this BMW is definitely worth checking out.

2005 BMW Z4 models

BMW offers the Z4 roadster in two trim levels -- 2.5i and 3.0i. The 2.5i includes 16-inch wheels with run-flat tires, a manually operated soft top (with rear glass), height-adjustable sport seats with leatherette upholstery (or rather, vinyl), cruise control, rain-sensing windshield wipers, a tilt-telescoping steering wheel, a CD player and power windows, mirrors and locks. The 3.0i adds 17-inch wheels, leather upholstery, a center armrest, aluminum interior trim, a premium audio system, automatic climate control and heated mirrors. Any of these features can be added to a 2.5i. Note that wheel-tire upgrades are part of the Sport Package, which also includes a lowered sport suspension, Dynamic Drive Control (a feature that quickens throttle and steering response), and on the 3.0i, 18-inch wheels. Other options include a power-operated top, bi-HID headlights, seat heaters, power seats, a DVD-based navigation system and wood interior trim. Dealer-installed items include a hardtop, a wind deflector, a CD changer, satellite radio and an alarm system.

2005 Highlights

Light Poplar Grain wood trim is available as a no-charge option on all Z4s. White indicator lights are standard across the board, and foglights and cruise control are now standard on the 2.5i. The 3.0i includes automatic climate control as standard equipment this year. Leather seating is no longer part of the 2.5i's Premium Package and is a stand-alone option, while all models receive additional black accents for the interior. The Sequential Manual Gearbox (SMG) is only available on the 3.0i, and requires the Sport Package. Last year's Convenience Package is history, though its contents are now either standard or part of the Premium Package.

Performance & mpg

The 2.5i model is powered by a 2.5-liter, inline six-cylinder engine that makes 184 hp and 175 lb-ft of torque, while the 3.0i uses a 3.0-liter straight six that generates 225 hp and 214 lb-ft of torque. BMW gets a lot out of its engines, and most drivers will be satisfied with the 2.5, which starts to feel winded only at very high speeds. Enthusiasts, of course, will want to go with the 3.0 and its smooth, continuous power supply. A five-speed manual transmission is standard on 2.5s, while 3.0s get a six-speed. If you don't want to deal with a clutch, you can opt for a five-speed automatic (with a Steptronic automanual gate) or, on the 3.0 only, a Sequential Manual Gearbox (SMG).


Every model comes with four-wheel antilock disc brakes, run-flat tires and a sophisticated stability control system. Passive safety features include rollover protection, side airbags, active knee protection and child-seat anchor points for the passenger seat.


With its stiff chassis, large brakes and multiple transmission options, the Z4 provides great driving pleasure -- easily managed when driven near the limit on twisty roads. Ride quality is smooth, but commuters may find Sport Package-equipped Z4s too firm for comfort. Wind and road noise can also be bothersome at highway speeds, but once you turn off onto your favorite back road, it becomes a distant memory.


The Z4's simple cockpit features a sweeping dash with a clean set of analog gauges, bolstered sport seats and little else to distract you from the road. Plenty of metallic trim comes standard, but wood trim is available for those who want to dress up their roadster a bit. Both the manual and power-operated convertible tops are easy to use, and the trunk has a generous 9-cubic-foot capacity (made possible by the elimination of the spare tire in favor of run-flat tires).

Too many problems
Jishnu Kinwar,06/26/2007
The car is good performance wise, fast, fuel economy better than expected. But it is not reliable and poorly built. Had problems with the retractable hood, steering wheel jammed, side windows not going down, memory reset all with in 18 months of ownership. Even today, sometimes when I close a window it goes all the way up and then comes down and one has to repeat several times before it shuts. After filing a formal complaint no action was taken by BMW. I have paid a lot of money for the car and at least expected a formal apology. Will never buy another BMW.
My First BMW
After a considerable amount of research, I purchased my first BMW about six weeks ago, a Maldives Blue over Beige, 2005 Z4 2.5i roadster with only 13,400 miles. I also have a 1977 MGB; guess I really like roadsters. After looking for a Z3M for a reasonable price, I turned my attention to the Z4. The reviews on the Z4 were, for the most part, glowing and I can say that this is the funnest car to drive I have ever owned. The power - even with the 2.5, is impressive, but its ability to stick to the road, its handling and its looks make it a winner in my book. It's a lot of fun to drive and to look at!
The Civilized (and legal) go-kart
This is my second car (and first BMW). Good God....I just realized what I've been missing. I moved to this car from an 07 Mustang. The acceleration is blistering and the car handles like it's on rails. To make it more insane, just initiate the Sport button and it goes like stink. This is driving in its purest unadulterated form which convinces me why BMW's are the ultimate driving machine. I used to take the metro in to work everyday however after getting the car, I drive in just because it brings a huge smile to my face and is the perfect anti-dote to a hectic day and NO I'm not exaggerating. It looks fantastic and flatters you. So much for getting a bike.
Highly recommend!
Paul in San Diego,10/14/2009
We purchased this car new in 05 and it has been outstanding. Not a single thing has gone wrong in 40k miles, it gets 32+ mpg on the freeway and combined mileage is 25-26 -- all much higher than estimated! The free services have been great too.

Should I lease or buy a 2005 BMW Z4?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
