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.

  By bobbyr35 - January 14 - 5:57 am

  Ok, we have had the Z4 for seven months. It has been driven in the USA and we brought it to Germany in November 2005. My wife drives it to and from Frankfurt every four days on A3, so for the two hour and 20 minute trip four times per week it is being driven at 120 mph on average. Too bad it is a US Specs.

  Dream Car under $50K - 2003 BMW Z4
  By David - January 9 - 3:19 pm

  I traded my Z3 in for this car and what a diffence. I love everything about this car. Everything that I felt could have been improved on the Z3 was greatly improved. The power band is smooth thoughtout the range. Handling is remarkable, it drives thru curves as if on rails. It has a sporty ride but is still not uncorfortable on long trips.

  great fun - 2005 BMW Z4
  By Tim Farrell - January 9 - 2:26 pm

  I took a road trip this summer through the Rockies and the car was a gas to drive. Very responsive, comfortable for long runs and very quick. Too bad there arent many places to open it up.

  More than I expected!!! - 2003 BMW Z4
  By Ab - December 29 - 5:41 pm

  I just got my Z4 for my 28th birthday (16255 miles in excellent condition from one owner!) and I am very impressed. This is my third BMW (currently own 06 330i and previously owned 03 325i) and with out fail it drives to my expectations. This car has every option except NAV and AT. Good acceleration (sport mode) and remarkably quiet. My wife was very impressed after the test drive and we got it! The car makes a better impression in person, than through pics. Interior is nice with remarkably good space, especially the trunk. Now we have to wait for the spring (live in MD) to truly enjoy it, but that doesn’t prevent us from driving it on the weekends!

  Z4 2.5 roadster experience - 2003 BMW Z4
  By mpbeaulieu - December 27 - 6:21 pm

  I have owned two 03 2.5 Z4s. One manual and one with automatic. Both have been excellent road cars and just a thrill in the hills. Change to the automatic was for the wifes desire. The automatic with the sequential manual shift works well and in general the automatic is easier in busy traffic. Both vehicles have been outstanding from a maintenance standpoint which includes excellent support from the dealer. While I would agree that the 3.0 would provide some extra horsepower, once you get the 2.5 rolling it delivers pretty well. Gas mileage (though not a concern) has been satisfactory electric top works great and once seated is quite comfortable. Only gripe is low top when getting in

  Now I look forward to my long commute! - 2005 BMW Z4
  By Zoli - December 21 - 1:20 am

  Bought 2 weeks ago what a FUN car! Im a big guy (61", 260 lbs) but still have plenty of legroom. 2 minor drawbacks - lots of squeaks from plastic parts if seats all the way back cant seem to get more than 19 MPG no matter how conservative I drive. Live in San Diego so I drive top down in December heated seats are a plus! looks great, sounds great, responsive, tight steering, the perfect toy!

  Z man - 2004 BMW Z4
  By the king - December 14 - 2:00 am

  Agile. Flat cornering. The best thing about the car is the engine. Great torque at any speed. Effortlessly accelerates from any speed. I have the sport package and the ride is mildy bumpy due to the 18" tires but the aesthics are awesome.

  1st BMW...not last for sure. - 2004 BMW Z4
  By secularist - December 9 - 9:48 pm

  Originally got this for my wife. Im stealing it from her and getting her a 5 series. I still dont understand why the styling is "controversial"...I get more approving stares and chatter about this car than I ever thought possible. We have the 3.0 with the Sport Pkg. Ride is firm for sure, but its such a go-kart when it comes to the twisties...love it. Gets great mileage for something thats so fast.
