Overview & Reviews

The BMW Z4 is one of the more intriguing sports cars available. It's the successor to the original Z3 and is presently the company's only two-seat sports car. Defining traits include a front-engine/rear-drive layout, a hunkered-down stance, a long hood and rearward positioning of driver and passenger. While the first Z4 featured a traditional soft top, the current Z4 model has a sleek retractable hardtop that makes this fun-loving roadster a more viable all-weather option.

The current Z4 also represents a slight change in philosophy for BMW's roadster. Not only does it sacrifice ultimate handling for greater ride comfort and overall refinement, but it also employs a highly fuel-efficient turbocharged four-cylinder as its base engine. The result is one of the most well-rounded sports cars money can buy. You'll need a lot of it, though, as the latest Z4 certainly doesn't come cheap.

Current BMW Z4
The current Z4 is offered with rear-wheel drive in three trim levels: sDrive28i, sDrive35i and sDrive35is. The 28i gets a turbocharged 2.0-liter inline-4 that produces 240 horsepower and 260 pound-feet of torque. A six-speed manual transmission is standard, with an eight-speed automatic available as an option. The 35i comes with a twin-turbocharged 3.0-liter inline-6 good for 300 hp and 300 lb-ft of torque; its sole transmission is a seven-speed dual-clutch automated manual (DCT). The 35is utilizes DCT and a revised version of the regular 35i's engine, boasting 335 hp and 332 lb-ft of torque with a temporary overboost function that pumps torque up to 369 lb-ft.

Though the primary distinction between these trims involves what's under the hood, there are some other equipment differences. The sDrive28i comes standard with 17-inch wheels, adaptive xenon headlights, keyless ignition and entry, dual-zone automatic climate control, eight-way power seats, Bluetooth and adjustable driving settings that change the programming for the steering, throttle and (if specified) automatic transmission. The sDrive35i adds 18-inch wheels, sun-reflective leather upholstery and sport seats. The sDrive 35is is similar but comes standard with an upgraded audio system and the performance-themed M Sport package (optional on other Z4s). Option highlights include heated seats and steering wheel, front and rear parking sensors and a navigation system.

In reviews, we've found the latest BMW Z4 to be an impressive and highly refined sport touring car, with a surprisingly roomy interior and decent trunk space as long as the retractable roof is raised. Although the turbo-4 makes less power than the old inline-6, it's got more torque, and fuel economy is substantially improved. Besides its rather agricultural grumble at idle, this is a sweet little engine. Should you want for more, the ultra-smooth and seriously quick six-cylinder models are bound to please.

The Z4 is generally a hoot to drive, especially if you go for the optional M Sport package and leave the adjustable drive settings in Sport mode. However, its reflexes and communication with the driver are a bit lacking due to a numb electric power steering system, a fairly hefty curb weight and a predilection for understeer. Still, we think most buyers will appreciate the Z4's firm yet compliant ride and accomplished all-around performance. A spirited top-down journey in a Z4 is a wonderful way to spend a sunny day.

Used BMW Z4 Models
The current, second-generation BMW Z4 was completely redesigned for 2009, as the previous coupe and roadster models were melded into one with the introduction of a retractable hardtop. The styling was revamped to be more curvaceous and fluid than the avant-garde first generation, while the interior gained some space, style and improved materials.

If you're looking at used second-generation Z4s, there are a few notable changes to keep in mind. From 2009-'11, the base Z4 was known as the sDrive30i, and it featured a carryover 3.0-liter inline-6 that produced 255 hp and 220 lb-ft of torque. The transmission was a six-speed manual or an optional six-speed automatic. This is a superb engine on its own merits, but it's not as fuel-efficient as the subsequent turbo-4, which replaced it for 2012 when the base model became known as the sDrive28i. The eight-speed automatic was introduced at the same time, supplanting the six-speed unit. As for the sDrive35is, it debuted for 2011 along with the M Sport package for lesser models. Finally, the sDrive35i could be had with a six-speed manual of its own until 2015.

The first-generation BMW Z4 was introduced for 2003 with controversial "flame-surfaced" styling. Originally, there were two roadster models available, identified as 2.5i or 3.0i. The 2.5i had a 2.5-liter inline-6 that made 184 hp, while the 3.0i used a 3.0-liter inline-6 that generated 225 hp. For transmissions, there was a five-speed manual (standard on the 2.5), a six-speed manual (standard on the 3.0), a five-speed automatic or a six-speed sequential manual gearbox (SMG). Standard equipment included 16-inch wheels (17s for the 3.0i), a manually operated soft top (with rear glass) and leather upholstery for the 3.0i. Major options included a power top, xenon headlights and a navigation system.

A significant update occurred for 2006, including the debut of the fixed-roof Z4 Coupe and revamped trim levels with new engines -- the 3.0i (215-hp inline-6) and 3.0si (255-hp inline-6). The Z4 Coupe was offered in 3.0si trim only. A six-speed manual transmission was standard on every Z4, while a six-speed automatic was optional. The largely disliked SMG transmission was dropped. Other changes included a retuned standard suspension for better ride quality, a revised final-drive ratio for improved acceleration and updated styling. High-performance M versions of the Z4 were also offered and are reviewed separately here.

Although we prefer the updated 2006-'08 models, every first-generation BMW Z4 rewarded drivers with an engaging driving experience. In reviews, our editors praised the car's sharp reflexes and quick acceleration, though the ride could be a bit rough -- particularly prior to '06 -- and the steering wasn't as communicative as some competitors. The Coupe possessed a slight advantage in terms of handling due to its added body rigidity.

  If you knew Suzy... - 2004 BMW Z4
  By ladepenb - February 4 - 10:00 am

  This is my first convertible bought almost by accident. My mother Sue had one, thus the name. It is red and it is sweet. Just ask anyone passing by as I drive though. Its the only one in town! It handles quickly and smoothly, responding well on any kind of road in any kind of weather.I feel safe in it, enev though it is a convertible. Its size suits me- I rarely need to carry anyone.I dont worry about cargo space- it carries enough groceries home. With the top down I can put on a hat and drive the turnpike without effort. The sound system increases enough so that the wind is not a problem. Id reccomend this car to any one who wants one and can afford it!

  good drive, plenty of fun - 2004 BMW Z4
  By drajax777 - February 4 - 10:00 am

  the 2.5 model is fast enough to get the driver in trouble but the brakes are excellent; the styling sets this car apart. my problem is with the run flat tires which seem prone to go flat and are expensive; in 12000 miles ive had three flats; no one is sure about a cause

  Z4 - no comparison (even to the Z3) - 2004 BMW Z4
  By DocHoz - February 4 - 10:00 am

  I owned the Z3 for 3 years and upgraded to the Z4 about a year ago. WOW says it all. BMW should pat themselves on the back for this one. The improvements on the interior from the Z3 to the Z4 are incredible and numerous. The exterior is the most obvious change, and that did take a little bit to grow on me - but I love it now. The handling, acceleration, braking, and response of the vehicle are fantastic - the sport button definetly gives it that extra "kick" when you need it. If you never owned a BMW or a roadster, I guarantee you will love it. If you are upgrading from the Z3, you will thank God you did. You will be amazed by all of the compliments you get.

  WOW - 2004 BMW Z4
  By cory - February 4 - 10:00 am

  I drove this car to New Orleans right after I bought it. This car stopped traffic on Bourbob Street. People were gawking and taking pictures. When we pulled up to the hotel, people walked across the street to ask about the car. People coming out of the hotel stopped to ask about the car and look at it. I thought the doorman would never have a chance to unload our car. This car still causes a stir wherever I go! WOW!!

  Great car, if you like to drive - 2004 BMW Z4
  By ChrisLee - February 4 - 10:00 am

  The best two-seater I have ever owned. Great acceleration, great grip, cornering is a pleasure, it is very safe and the drive is always controlled, the steering is unbelievable, it is very comfortable and it looks great. What else do you need from a sports car? On the downside, I have had several warranty issues, there were material flaws and the repair crews were not always familar with the car and with their own job (e.g. destroying things as they fixed others). Last, my 2 cents: get the SMG (semi- manual gearbox) if you can. It is the best shifting experience I have ever had and far superior to the other alternative of manual shifting.

  My wifes valentines present - 2003 BMW Z4
  By GaryP - January 21 - 2:00 am

  I love this car. I bought It for my wife as a valentine present and she really enjoys driving it. The only problem that I have seen is that the factory paint job does not reflect a $40000. vehicle. When we picked it up from the dealer it was obvious that he hadnt checked it out because the drivers electric seat wasnt working.

  Best two seater ever! - 2004 BMW Z4
  By moniquita - January 4 - 2:00 am

  After owning BMW for many years, the Z4 3.0 was the first that convince me to get a two seater, It doesnt feel "small" at all. I love the looks, may be controversial because is a bit ahead. The trunk space is better than the M3 convertible and the 328iC.Very fun to drive (I have the 6 speed manual) and the sound of the engine is perfect!

  Not So Hot - 2004 BMW Z4
  By WVSAM - January 4 - 2:00 am

  Sorry to say, but my Z4 performs hot, but is uncomfortable, and rattles like a crib toy. The trunk is so small that literally it wont hold a golf bag. The Z4 looks good, and drives well, but for 45 grand it should be more comfortable and not rattle and squeek.
