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.

  Not a Suitable 5-series Replacement - 2007 BMW Z4
  By Robin - August 26 - 7:44 am

  A good 2nd car for fun in the sun, with great looks and handling, but not a suitable replacement for my 2000 540i. The wind noise on the highway and comfort on bumpy roads is not very good, so consider this for daily travel. More of a weekend "lets have fun" car. Personally I think our 2003 Z4s 5-speed shifted smoother and quicker and its ride was not so harsh (as I recall), so Im a bit disappointed by this 2007 Z4. The 6-speed shifting bothers me the most, since I do a lot of it! (Oh well.)

  Running Young - 2003 BMW Z4
  By Dean - July 19 - 1:45 pm

  Soon to be 52 and adding a 16 year old daughter to the highway led to this purchase. Wow! Amazing how quick memories return to the 70s and 80s open tops of 280z, TR6, Spitfire and my first, 1969 Fiat. Wonderfully balanced handler, just enough interior space, stunning exterior lines. Hard to read electronic displays when top is down, cup holders a waste, and no locking compartments. Small issues given every minute of fun youll feel behind the wheel!

  Z is good for me - 2004 BMW Z4
  By throb - July 15 - 9:17 pm

  I got this car when I finally could afford one and wow it did not disappoint. I got the SMG based transmission and that thing is a total blast. I love the car so much that I am leasing a new 07 Z4 3.0si starting in 2 days! My only gripe is that the Z series is always behind in cool technology that the 3 series has. No siruis radio. Pathetic. Its a very small gripe on a kickin car!

  Great 2nd Car - 2007 BMW Z4
  By DaveinCT - July 7 - 10:47 am

  The car does what youd expect... great acceleration, exhaust note, handling. When driven with the top up on those not-so-perfect days, there are a few rattles in the roof/seats. Its not as fast as a Vette off the line, but the seats are exceptionally comfortable, the THX stereo sounds awesome, and the nimble handling make it all worth while in the end. However, if you plan to do most of your driving with the top up or in the winter months dont bother!

  Mid Life Crisis - 2003 BMW Z4
  By burnsmw - July 6 - 9:49 am

  I traded in my 740iL for something a little smaller and more fun to drive and was not disappointed. I have been driving BMW since the early 90s and have had nothing but positive experiences with them all. I started in Europe where the BMW is at home on the autobahn then moved here to the States. The Z4 is quick and nimble, and though I chose the smaller 2.5 it has more than enough power to get things moving. Mileage is great for the power it has. The engine is typical BMW, VERY smooth and quiet. Trunk space is large for the class but interior storage is lacking. I have the sport suspension which is, at times, stiff enough to jar you when large bumps are found. Handling is great.

  Too many problems - 2005 BMW Z4
  By Jishnu Kinwar - June 26 - 11:41 am

  The car is good performance wise, fast, fuel economy better than expected. But it is not reliable and poorly built. Had problems with the retractable hood, steering wheel jammed, side windows not going down, memory reset all with in 18 months of ownership. Even today, sometimes when I close a window it goes all the way up and then comes down and one has to repeat several times before it shuts. After filing a formal complaint no action was taken by BMW. I have paid a lot of money for the car and at least expected a formal apology. Will never buy another BMW.

  Pure sports car - 2007 BMW Z4
  By Loren - June 14 - 6:49 am

  I leased a 2007 BMW Z4 3.0si to use as a daily driver, as my wife drives our 2006 Land Cruiser. It did not take long to realize that this car is for weekends only! It is cramped and the ride over older roads will knock fillings out of your mouth! That said, it is a great sports car. The handling, transmission, and power are great. It is an absolutlely fun car in the cool of the morning or for a romantic drive in the evening, but it is not intended to replace a sedan. I am taking the penalty to get the 2008 535i!

  Fun for 6 mos so far - 2003 BMW Z4
  By amk - June 4 - 10:00 am

  This is my first BMW and convertible. I was not sure if I will like a convertible, but this car is so comfortable with top up or down (my usual mode of driving), that I wish I bought a convertible earlier. The car has all the comforts/techno gadgets I was looking for, and all work well together. Handling is superb, and the balance of performance, handling, and comfort is extraordinary. I highly recommend the car to anyone looking to get into this type of vehicle.

  Watch that paint! - 2004 BMW Z4
  By MCP - May 28 - 10:00 am

  This is a wonderful car to drive. The 2.5 is a little sluggish from the line but makes up for this with impressive high speed power on the highway and in the turns. The car is an attention getter. The top works well and quickly. The paint job on this car leaves a little to be desired. This is a $40k with features, but it has the paint job of a car costing about $10k. This car scratches easily. It requires copious amounts of wax to cover these imperfections.
