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.

  Most enjoyable car Ive owned - 2007 BMW Z4
  By aquila163 - May 1 - 9:51 am

  This is the most enjoyable car I have ever owned. I got my 07 Z4 Si on a 2 year lease. After 18 months I had a lot of miles left because I also owned my last Corvette and can only drive so much. My wife and I took a 2100 mile road trip to Disney World to use up some miles. When we got back, I sold the Vette and bought this car off lease. I now have just over 4 years in the car and now that the original warranty has expired I have made an extensive search for a replacement. I CANT find anything I like better so Im keeping it. It gets over 30 mpg on the highway and the sports car ride is tight but never abusive. I would recommend this car to anyone looking for a genuine sports car.

  Fun Fun Fun - 2008 BMW Z4
  By Robert - November 12 - 2:00 am

  This car is nothing but fun to drive, the steering is a little startling on grooved or rough pavement, Sports Package). Takes off in any gear even on the interstate. MPG is amazing for a performance car of this caliber. If you can afford one, go and buy one. Best to get a CPO as opposed to buying a new one, save some serious cash. Mine had only 19K on it. Make sure you get the SI model as opposed to the i the difference in horsepower is worth it. Watch out for cement bumpers, get too close and you will mess up that one piece front bumper. Also watch out for pot holes, not much clearance on the underside.

  Makes you feel young! - 2010 BMW Z4
  By captainmarvel - November 8 - 2:00 am

  This is my first BMW purchase and I am very pleased with the vehicle. Driving the vehicle has been a real please. The driving and steering response is excellent. The miles per gallon 23.5 city and highway has been excellent. Too bad the vehicle does not use regular gasoline. The run free tires are a good option. However, if low tire pressure occurs, the dashboard only indicates low pressure. It does not tell you what tire is low.

  Near-perfect roadster - 2011 BMW Z4
  By Thom - November 2 - 2:00 am

  After several 3-series coupes this is my first ever roadster. Although inherently impractical, it is much fun to drive - I love the throaty growl and sharp steering turn-in.

  Can do - 2003 BMW Z4
  By RG - October 3 - 2:00 am

  Great running car. Driver seat wears where seat belt rubs exposing under layer. Car is good handling and gives full feel of road changes. Actually drove around deer standing on freeway while going 55 and it felt like 25 mph. Quick response steering and extremely stable. No dealerships for 400 miles found good private shop. Still a thrill to drive every time after year and a half. Switched from motorcycle to z4 no regrets!

  Certified Fun - 2008 BMW Z4
  By CertifiedFun - September 11 - 2:00 am

  I have been waiting patiently for the opportunity to own a Z4 and the day finally came. I purchased a CPO car so that I would have warranty coverage just in case. I couldnt have gotten a better deal or a better car. The performance is top notch. I smile every time I get in or out. I got the Steptronic manual with the Sport package and the paddle shifters on the steering wheel. I love the power top and heated seats. This thing is the most fun you can have for 31K.

  A great car even after 6 Years - 2004 BMW Z4
  By PerryM - August 26 - 2:59 pm

  So I bought a 2004 Z4 with 17K miles on it a moth ago. Drove it from Pittsburgh to Chicago to get it home and it was a blast! Wow! This car is comfy, roomy, powerful, reliable, and fun! The 2.5 has quite the power and I cant really notice a difference vs. the 3.0. What more can you ask for? The prices are very competitive these days for a pre-owned. I test drove a Z3 10 years ago and hated it so I bought a MR2 Spyder. This vehicle tops them both by far. Fairly quiet with the top up, especially for a convertible. and you cant really feel the wind too bad when its down.

  The perfect roadster - 2011 BMW Z4
  By J. R. Leonard - August 19 - 8:42 pm

  I took BMW Performance Center delivery of my 2011 Z4 sDrive 35i. That means that for four on-track hours BMW race drivers taught me how to explore safely the limits if a Z4 identical to the one I was purchasing. That experience and teaching has made my ownership much more pleasurable and rewarding than it ever could have been otherwise. I cannot recommend it too highly. The Z4 is a classic roadster and as such is completely at home on the country roads and Blue Ridge Parkway of my home state. The exhaust note is wonderful, nostalgic, echoing Healeys of old. The engine power is more than adequate and the driving experience, top up or top down, is immensely pleasurable. BMW got this car right!

  Dream Car - 2006 BMW Z4
  By Joel H - August 12 - 10:15 am

  I have owned this car since October 2009. Bought it used with 36k. When I purchased it the channel changer on the stereo was not working. It was still under warranty. The dealership replaced the stereo with a new one. Other minor issues including front brake rotors occurred and the BMW dealership took care of them all at NO CHARGE. The warranty is the best. The car handles like a dream. It certainly is a head turner. I had a minor accident because of a blind spot when you look back to back up . I love this car. It handles like a dream and the dual steptronic transmission is terrific. I am a BMW customer for life. The customer support and service is the best I have dealt with.
