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.

  Own one and youll understand! - 2008 BMW Z4
  By Marcos - July 15 - 11:35 am

  This is my first Z4, I have always had Porsches, my last one was a Cayman S. Let me tell you about my Z4 in a nut shell... its impressive design and agility gave me what I needed to get off my Cayman and look into my "now present and future" BMW relationship. The car handles like its on rails, it brakes like no other car Ive driven before and to top it all on wet surfaces you can not even tell that you are driving in the rain, it just feels like a 997 Turbo handling in a smaller car. I will definitely get another BMW after my lease is up on this baby. I will recommend to anyone that is looking for performance, safety and value at the same time. A real head-turner! Enjoy it

  Zed 4 3.0i - 2006 BMW Z4
  By Kipper - July 12 - 12:58 pm

  I bought this car after test driving SLKs, Miatas, Z300s, Boxsters and S2000s. The Zed 4 3.0i, although not the highest performing Zed 4, seems to be more refined than the other cars I tested. The handling is crisp and throttle response is quick. The 3.0i is not particularly quick for this class, but does provide a 0-60 mph time under six seconds. It is a good highway cruiser but a bit bumpy on the backroads. However, I never lost any confidence in handling while on bumpy roads. Im averaging 24 miles per gallon, driving in both highway and city. The body style is a real head turner and the interior seems to fit the body style.

  Fun and practicality in one package - 2004 BMW Z4
  By Matt S. - July 1 - 11:41 am

  I bought this car as a CPO with 13,000 miles on it. I have not been disappointed at all. Living in Southern California, this car does it all for me, from running to the grocery store to taking it for a run in the mountains. This is not a weekend toy for me I use it regularly. I drove this car cross-country and was pleasantly surprised by comfort level it gave me on a 6000 mile trip. Its performance is excellent it sticks to a mountain road like glue even on wet/icy pavement. I have every option but the nav system the power drivers seat definitely ups the comfort level. I definitely recommend the 6 speed manual its a pain sometimes in LA traffic, but worth it overall.

  My favorite BMW yet - 2004 BMW Z4
  By Advantyper79 - June 11 - 10:00 am

  Pick up my Z4 3.0 last weekend, all I been doing is driving ..driving ..and driving.. the car is amazing, handling is superb.. much more solid than my 330i. The only complain I have is the trademark BMW "THUMP" when you close the door is gone and the door handle feels cheap like a honda or something.. and the mousetrap sunvisors are not too good when I pay over $45k for the vehicle. But the performance, handling and all the ATTENTION you get with the car is well worth every penny... The more I drive it the more I loved it...

  Design getting better with age - 2007 BMW Z4
  By rdavidz - May 24 - 9:48 am

  When the Z4 came out to replace the Z3, I thought they ruined the idea. Its a much different car and when you drive it, you can forget about the Z3. The lines on the car all seem to fit and have purpose, even though Im not a fan of the Bangle designs. I bought the Z4 3.0si convertible which is a fast car and looks unbelievable with the sport package and 18" wheels. The sport package completely changes the look and driving of the car, its a must. Its fast enough even with the auto trans which has the paddle shifters. The extended leather and premium M seats are a must too. All the options raise the price, but if youre seriously considering this car, cost is not a concern.

  Two years plus - 2005 BMW Z4
  By George Warren - May 18 - 10:47 am

  Being a master diesel mechanic for at a Freightliner truck dealership for close to thirty years I believe I am a fair judge of quality. I have really enjoyed this car for over two years. When you get off work there is nothing better than jumping into your Z4, dropping the top and hitting the road. I have owned many new cars but this is the only one that is as much fun to drive now as it was when I bought it! If there was anything I would change I would redesign the drink holders as they spill hot coffee on your leg on turns, the seats should have higher side bolsters so you don`t slide around so much on turns. And get the Xenon lights which was the only option I didnt get. BMW - great car!

  I call it my little zippy for a reason! - 2008 BMW Z4
  By smd - May 15 - 5:29 pm

  I just recently purchased this car. And oh what a car it is. The handling on the Z4 is amazing, not to mention its one sexy car. Options that are musts are the leather for easier clean-up with a convertible, the premium package with the auto top, as well as the heated seats so that you can take advantage of the top down on cooler nights. Dont waste your money on the upgraded speaker system. The one it has is amazing! My husband is 63" and has plenty of headroom. However it is a little cumbersome to get out of compared to a normal car. But hey, you are driving a sports machine who cares right!

  Quality with Flaws - 2006 BMW Z4
  By Peter J - May 12 - 8:39 pm

  Interior build quality is disappointing due to use of cheap plastics. Been back to the dealer 4 time because of annoying squeaks and rattles but dealer cannot fix. The high performance driving experience is marred by these constant squeaks and rattles, even happening at low speeds. Ride is extremely harsh. On anything other than perfect roads you can feel everything down to the road paint. The car is easily pulled from side to side by uneven roads. Tire noise is high. Of course this kind of handling is to be expected for this type of car. Otherwise, the car has exceptional performance.

  Z4 truly a great car - 2006 BMW Z4
  By Olivier - May 10 - 6:09 pm

  I have always been a corvette lover, but the Z4 took my heart away. Incredible handling, acceleration. The sport package in my opinion is a must to truly appeciate the driving experience of a Z4.
