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.

  Bang for the Buck! - 2006 BMW Z4
  By Z Dog - April 1 - 8:51 pm

  I had been looking at getting a small sports car for a while. Looked at the Boxster, Corvette, Audi TT, and the BMW. I loved the Z4 for the unique design. Once I drove it, I was hooked. I paid $30k for this gem. Silver on Black. Great for normal day to day, then just push the "sport" button and... she becomes a whole new car. Throttle response, steering and overall power seems to explode! Its like an alter ego. I drove the M roadster and it is just a Freak! The 3.0si is a dream for much less. Anyone who complains about the trunk space or the rigid ride should have chosen otherwise. Take a shorter trip, pack a smaller bag, and use your buddies truck to go to home depot. Great Car!

  Z4 3.0si - 2006 BMW Z4
  By z3toz4 - March 29 - 3:20 pm

  I had my Z3 for twelve years, finally bought a Certified Z4. Be very careful with Certified, even though BMW has fixed all the problems that have come up, mine has been in the shop for MAJOR suspension and engine problems. It has been in the shop 20 of the 60 days I have owned it. Not what I expected from a BMW Certified car. Now that I think I am past the problems this car had, I really am enjoying driving it! Much smoother, powerful ride than Z3.

  What a snow ride - 2004 BMW Z4
  By Mecho - March 26 - 10:41 pm

  I had this 2004 Z4 3.0 for the last 4 years. Silver titanium. It is impressive, I love it very much. Drove it all year around in Detroit and Minneapolis. This car is great on snow with the right tires. It is fun to drive. I test drove the SL55 AMG as my next car possibly. Let me tell you, I have to think twice now. Z4 is even more than what we may think. It has been difficult to choose something else after you drive this car. Most likely it will be SL55 AMG though for me tough decision to move from the Z4 even after more than 4 years driving it all year around. Never drove a car for that long. Go get one dont even think twice about Z4. :)

  3 Years Later - 2006 BMW Z4
  By Garhuff - March 22 - 8:11 am

  I ordered this car after seeing it at the Autoshow, even though I was only able to test drive the convertible. I took delivery of it at the factory, and I have loved it ever since. I still get a thrill when I see it parked in the lot. I constantly get thumbs ups, wherever I drive it.

  Fun on wheels - 2006 BMW Z4
  By Mikenmass - March 17 - 1:40 pm

  With todays prices its hard not to consider an upscale model car. The styling is great but the engine and handling is what is special about a Z4. You probably need alternative transportation for the family or pets but a ride in a roadster will always be a treat.

  First Bimmer - 2005 BMW Z4
  By babyjoe - March 1 - 6:36 am

  I thought a Harley would satisfy my craving for a "fun" vehicle. It didnt. Few months after selling it, I found myself looking at the Miata. Drove one and immediately decided nope. Next found myself looking at the Z4. I absolutely love the styling. Knew nothing about them. Saw a Merlot 05 and fell in love. Drove my first BMW a couple of days later and knew I was hooked. Well I bought an 05 Merlot and havent looked back. Best car in the galaxy. Fun, fun, fun and it does turn heads. Gas mileage ensures the fact this was a great decision. Need to change out the run flats and need warmer weather then the fun begins again. You gotta try one of these if you dont do anything else with your life!

  Donkey Cart - 2008 BMW Z4
  By Wader - January 29 - 4:12 pm

  I purchased the coupe off the showroom floor with the sports suspension package. The roads in Northern Illinois are not the best so my wife refers to the Z4 as "the donkey cart". Regardless it is a blast to drive and I get many compliments on its appearance. The dealer experience has been outstanding.
