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.

  Beautilful to look at but... - 2004 BMW Z4
  By adunkle - July 23 - 6:07 am

  This car is beautiful!! Very sexy and sleek. Just looking at it, it drips of performance and wants to go fast. Thats the only positive things I have to say about it and why I have kept it but am considering moving on. The car seems to have one malfunction after another with no end in sight. To list a few of the more recent issues that needed to be fixed: Convertible top motor, all abs sensors, new starter and new coolent reservoir. Add the regular maintenance cost such as breaks, tires and other miscellaneous things that just need to replaced and be ready to fork out some serious $$$! This is my second German car and all I have to say is, "So much for German engineering!"

  Good Car For The Price - 2003 BMW Z4
  By oldmarine5 - May 29 - 4:33 pm

  Bought from dealer with 5000 miles on it. Also, had a Z3. The style of the Z4 is not as nice as the Z3 but many features of the Z4 are an improvement. Great engine. Smooth with plenty of power. I am 62" and , unlike many two seaters, has good room for the driver. Expensive to maintain, but I only drive it on sunny days with the top down. Just hit 20,000 miles. Red color and gets lots of compliments. I am satisfied.

  My Dream Car - 2011 BMW Z4
  By adonis13 - March 1 - 1:38 pm

  Ive always wanted a BMW Z roadster ever since I test drove a Z3 in San Diego. At the time, I had just started working full time. I have always been an Engineer, but at the time I had a mountain of debt. When I finally had the means to purchase my dream car, Chris Bangle (Germanys answer to Sir Mix-a-Lot) violated the Z3s successor, the first generation Z4. So, I had to wait 7 long years for that abomination to leave the stage. The E89 Z4 was worth the wait. Strangers and acquaintences alike come up to me all the time to tell me that I have a beautiful car. I dont need a car that costs any more money, has any more performance, or looks any better (if possible).

  What more do you want! - 2004 BMW Z4
  By jimlarson - February 12 - 11:08 pm

  just simply a Fun, fast, unique car! i just bought a white 04 z4 with red leather and couldnt be happier! drove a TT for years, loved it, but like the z4 much better because of comfort and exterior design. interior isnt as fancy as i would like, but who needs a GPS when your having fun getting lost driving around! very low to ground, makes for a little awkward "in and out" ... but who cares! gets tons of compliments, looks amazing from all sides. you dont see these cars all over the place which makes them even more unique. great around corners, i live in pacific northwest, and wet windy roads are super fun! ... nice and quiet with top up!

  3.0i Sport Package - dream car! - 2006 BMW Z4
  By solarus - July 20 - 9:53 pm

  I am still in shock after I purchased the 2006 Z4 3.0i fully loaded with winter, comfort and sport packages for around $20,000 with 50k miles on it. I simply would have to search for a reason why buy anything else - including new, newer, or different model sport cars. With a push of a button this thing performs as if it had turbo or supercharged engine. The interior, though not Jaguar comfortable, hugs you tightly and holds you in one place to enjoy the show. Super tight sport suspension can take almost any corner at mind boggling speeds you can throw at it. Ditch the "run-flat" tires. Buy whatever you want at Tirerack.com for less than $500 and your cars shoes are back in order.

  Disappointed in Quality - 2003 BMW Z4
  By magicdolphin - November 4 - 7:41 pm

  I only have 30000 miles on my BMW Z4 2003 I bought it out at the end of my lease the elec. motor for the convertible top short circuit due to run off water that enters the plastic housing where the elec. motor sits in. The water cant drain and the electric motor will rust and quit. Very expensive repair, poor design. I had the housing replaced in 2008 and now it needs to be replaced again and of course my extended warranty wont cover the repair nor will the dealership ... very poor design indeed and not at all what I expected from BMW. I also just had to replace the rubber around the windshield and the cowel due to dry rot. I would have thought the convertible roof of a BMW would last

  The Perfect Roadster - 2011 BMW Z4
  By rajparmar - June 25 - 3:52 pm

  I recently got the 2011 z435i with the 7 speed automatic, premium package, sport package, premium sound. It combines luxury, style, and performance better than any other car out on the road. It has a distinguished look and gets a lot of attention on the road. You can drive it like a true sports car with its high performance options, large horse power, and great handling. Or you can take it for a luxurious lazy sunday drive for hours with the top down, nice sound system and comfortable spacious seating for a 2 seat car. It wont beat the Porshe Boxter on a track but I feel the interior comfort, comparable unique style, and price difference make up for it. It is a very sexy fun car to drive

  Drive them all and youll choose this one! - 2011 BMW Z4
  By nyfo - June 1 - 12:53 pm

  Purchased this vehicle coming from M6 through E63 AMG. Although M6 is very fast, SMG tranny is HORRIBLE in real life. AMG is an absolute MB service dream (8 weeks in service out of 6 months of ownership). So after browsing 911, SLK and boxter - I decided to go with the Z4. Hardtop convertible is awesome. Features, although very pricey (base $52k, mine $66K) are all there. Handling, although criticized, is very adequate. This car is not built to be driven on track only, it is a very comfortable sports car adaptation to real life conditions. Highway cruising feels like a 7. Thumbs up, BMW, cant wipe the smile off my face every time I drive it! Bi turbo is a mast, base model lacks power, etc.
