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.

  From a Z-3 To a Z-4 - 2006 BMW Z4
  By K-Bone - October 24 - 3:52 pm

  Well i went from a z-3 to a z-4 miss the curves and the shark gills on the side, but love the power cornering one touch roof and better sound system then the z3.Cup holders in a great spot,not in way of stick shift. Larger trunk,can fit golf clubs and small cooler in this one. They also put a glass window in this one instead of the ole plastic one. Great lighting one the front light up the road also. Owned a 2003 Boxster also at one time and this is less of a money out of pocket kind of car also.

  My Toy - 2006 BMW Z4
  By Bob - October 7 - 5:02 pm

  I finally bought a 3rd car for our family. I have always wanted a convertible sports car. After a lot of test driving and research, we decided to purchase a used 2006 with 8,000 miles on it from the certified lot at our local BMW store. We have absolutely no regrets!! I had my heart set on a Porsche Boxster, but after test driving the Z4 I was sold. We have had it for over a year and it still puts a smile on my face every time I get in. Strong acceleration, handling, and comfort. I even drove it 487 miles in one day with the top down and loved every minute of it!!

  Dependable? - 2003 BMW Z4
  By Morduk - September 30 - 11:16 am

  Bought the car in November of 2003. Loved the drive of the car and was impressed with the its lines. Within the first 3,000 miles, had to repair both front tires due to puncture. After 10,000 miles had to replace all 4 tires. Inflation pressure listed by BMW was not the same as required by the tire company. No problem with tires after proper inflation. Soft top would not function due to a leak in system. Fixed under warranty. Problem with front suspension system. Fixed under warranty. Few months after warranty ended, master computer system failed. Replacement value $1,300. BMW paid half. Currently car is in shop for front suspension system problems again.

  What a car! - 2007 BMW Z4
  By DOUG - September 24 - 1:37 pm

  Ive had my Z4 coupe 15 months and have 17,700 miles on it. First car I have "loved"! Im 65 and behind the wheel, I feel like 25. I have driven just about all sport cars, but none have turned me on, like my coupe. I drove a Porsche on a race track once, but this coupe will beat that Porsche on any curve anytime. And I might add, for half the price. The Z4 coupe is and will be the only car for me. When Im too old to drive, Ill sit in my rocker, rock the day away, while looking at my Z.

  Love My Merlot Roadster! - 2005 BMW Z4
  By kgmilliron - September 12 - 7:35 pm

  Ive waited 40 years for this narcissistic NOT a "mom" car and was debating b/w the mercedes slk and the Z4. I could not be happier with my choice! Fun to drive, had it a week and its great! I was worried about road noise compared to the hard top SLK, but there was very little difference. We replaced the run flat tires immediately and it made a huge difference in the "comfort" of the ride. BMW service is unsurpassed and the style is unbeatable. For the price and reliability I give it a "10". If youre on the fence, commit, its worth it! The power top is a must!

  Garage Furniture - 2004 BMW Z4
  By Frank Ferracane - September 9 - 2:00 am

  Its so pretty I hate to take it out of the garage and get it dirty. But, on sunny days I take it out and travel the west coast of Florida. This car turns heads more then any other car I drive. Any time I see another Z4 on the road they always smile and wave. All us Z4 owners know we are in a cool car.

  What I expected - 2007 BMW Z4
  By Retired & loving it - August 27 - 3:39 pm

  I bought this car as a retirement present present to myself (curiously, I see a lot of guys (mostly) my age driving these cars!). I have thoroughly enjoyed driving for short hops. I have taken 3 trips of 500 miles and this is not the car for it. The RFTs amplify the bumps on bad roads, and we all know what I-95 can be like. Other than that, it is so much fun to drive and cornering is a terrific experience. I have the 6-speed manual and wouldnt consider the automatic - that would just be wrong in a sports car.

  I love it sooooo much - 2008 BMW Z4
  By LOVE my new toy! - August 17 - 3:13 am

  I am a mother of four kids whose oldest one just got her license - so we are a three car family. But who needs three big cars? Not us! I work full time and drive frequently for work - and this car brings a thrill to even the most mundane errand. I finally got a toy for myself, and I have no regrets whatsoever. The mileage is good and it is incredibly fun to drive - I am the envy of all my friends. I think it is a BEAUTIFUL SEXY car and I will be in tears when the lease is up. Might just have to get another one!

  rear ended after owning car for 4 days - 2005 BMW Z4
  By Jeanne S - August 10 - 11:55 am

  For the short time I had this car before being rear-ended, I loved it. If you ever have the misfortune of being hit (3 times before she stopped) from behind by someone doing 45 mph, know that this car is definitely well-engineered. I walked away from the accident with only whiplash. It could have been much worse had I still been driving the miata mx5 I owned previously. Fun to drive, I just hope I can look at it the same way after I get it repaired.
