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.

  Z4 a smile - 2004 BMW Z4
  By AUNDIK - May 4 - 2:00 am

  I love this car (4th BMW - first 2-seater). The top can be up or down - the exhileration is the same. The fit and finish are top, and the instrument layout is clear and logical.

  Instant, incredible fun - 2007 BMW Z4
  By Fred - April 22 - 7:37 pm

  Nothing like completely changing a day as to hop into the Z and spring off into the night. Incredible driving experience and am lucky to have many windy roads to enjoy. Fun, fun, fun!

  2007 BMW Z4 3.0si 6 spd manual - 2007 BMW Z4
  By Dee - April 21 - 12:16 pm

  I purchased my Z4 for pleasure driving only (sunshine time). This was to replace my previous convertible of 5 years that I sold last year. After test driving numerous cars, once I sat in the Z4 I knew this was one for me. It amazes me every time I take it out for a drive! Usually there is a limit that a car can handle in driving performance but I still cant find it with this Z4. Its like "I can take that, I dare you to go farther!" Needless to say, this is a car that can get you in trouble. BMW really knows how to design and build an exceptional convertible. They have mastered what it takes to create an unparalleled driving experience. I am impressed.

  Noises.... - 2003 BMW Z4
  By Stephi - April 14 - 2:00 am

  The car is fun to drive but I have had some issues with the powered Top. After 2 opennings, the Top broke on the left part.After 1 month, there was a noise in the motor. The seat belt of the passenger is making noise against the door when nobody use it. The Top does a small crispy noise when it is down.

  Dream Machine ... - 2003 BMW Z4
  By z4driver - April 14 - 2:00 am

  Very fun to drive. The edgy exterior style is wonderful. Interior is very spacious and comfortable. Major improvements over the Z3 include Run flat tires, which allow much bigger trunk space, thus making it a more practical car. In addition, the back window is glass, rather than plastic, which comes in most convertibles. The seats are much bigger, with much more leg/shoulder room than in any convertible Ive seen. You need to drive with the top down on a cold day to appreciate the heated seats option. Power top is a must-have.Interior guage style has been redesigned. Sound system is simply incredible.

  Want to have fun? Drive this! - 2007 BMW Z4
  By Joe - April 9 - 11:34 am

  Purchased mine certified used with 11000 miles on it. Very fun to drive! Looks fast, is fast. I rarely used to put the windows down in my old cars, but with this car I put the windows and top down every chance I get! I get many compliments on it--it is simply a sharp looking car and turns plenty of heads. I love how Z4s are not as widely popular as, say, a 3-series and that was a big reason why I purchased mine. If youre looking to buy, seriously consider the metallic silver color with premium package. With the sharp angles of the body styling, silver looks beautiful!

  BMW Z4 - 2003 BMW Z4
  By docmatt - April 3 - 10:00 am

  My major complaint is with the low front spoiler. It scrapes on any bump or steep driveway. Very poor design for the road. Also, should be able to start in sport mode and not have to switch it on every time.

  Driving has never been this fun!! - 2005 BMW Z4
  By Mike Smith - April 1 - 6:36 am

  This car is so much fun it puts a huge smile on my face every day! Fantastic blend of power and elegance. Economical too, I have consistently gotten 27 MPG with mostly highway driving. This car has a sporty ride but absorbs the bumps well, despite the 18" alloys that come with the sport package. You must have the sports package, the standard 17" rims make the whole car look bland. The red leather interior is gorgeous. No reliability problems whatsoever. No rattles or electrical issues. The upgraded sound system is awesome. The trunk space is good, even with the top down! You can easily fit two suitcases in there, or a couple sets of golf clubs. Buy this car, you wont regret it!

  My Zs - 2004 BMW Z4
  By Charles W. Simmons - March 29 - 10:00 am

  I had previously leased a 2001 Z3 Roadster because I wasnt sure if I wanted to own the BMW. I loved the Z3 and at the close of the lease I went to the dealer to purchase it. In 2 years I had driven 42000 miles and loved every mile. Well I test drove the Z4 and decided to purchase the 2003 Z4. So far I am not sorry.

  I LOVE MY Z4 - 2003 BMW Z4
  By Robert Dugan - March 21 - 4:07 pm

  This car hugs the road so nicely it just give me goose bumps when I drive it. My mother thinks the car is the coolest and loves driving in it with the top down.
