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.

  This car is a Gift - 2005 BMW Z4
  By Dustin - November 28 - 12:54 pm

  I just came back from driving this car from Montreal to California and back with my 12 year old son. I logged 10000 miles without a problem except worn rear wheels and a nail, the red light came on telling me I had a flat, nice feature, but not a problem with runflat, drove 10 miles to a garage that could fix it. It was a dream to drive on route 1 of the California coast and through the Arizona Desert. This was a trip of lifetime, and lots of room in the trunk for 2 people on a month long trip, really, well summer time in the heat, not many pants to take space, packed light, but lots of room, I would drive 12 hours straight, not sore at all no need to stop and stretch. fun great car!!!

  Sexy, Sleek and Fun to Drive! - 2006 BMW Z4
  By Lisa - November 25 - 1:28 pm

  When I went to the BMW dealer, I saw this car and fell in love. After the test drive it was an obsession. It handles like it is on rails, it thrills at every turn. It is one hot car and I consistently get 25.5 miles per gallon hwy and city. It is a headturner and it backs up its looks. It is like a motorcycle with a cage around it. It is that ultimate driving experience every time you step into it. It looks as if it chiseled in marble. To me a work of art. Me and this car were made for each other. I recommend it. Great sports car.

  Roadster - 2007 BMW Z4
  By Bijan - November 15 - 3:52 pm

  Great car, love the styling straight-six sounds great and the manual gearbox is super-smooth. Love the seating position, as well as the interior space with the easy-folding top up. Very nice to drive, the car is very communicative and gives you lots of confidence, brakes are amazing and stop the car with little drama. My only complaint is with the interior build-quality. The one-piece door panels are great, but the steering column is tilted, a cup holder is broken (I dont even use them) and the transmission tunnel plastic trim squeaks when you rest your arm on it. Besides that, everything you touch is of high-quality and just driving it takes your mind off its few squabbles.

  What FUN!! - 2003 BMW Z4
  By fogelfield - November 14 - 2:00 am

  This car is just plain fun to drive. It has made my commute something I look forward to as I get in the car. Questions pop to mind like, Will I have a clear run through the onramp to really floor it? and How many waves will I get today? If you can afford to have only two seats and are ok with a big smile on your face when you drive, buy this car.

  Z4ME - 2003 BMW Z4
  By Z4ME - November 4 - 4:46 pm

  I bought my jet black 2003 Z4 in 7/08. I have put on 6,000 miles in Minnesota and have enjoyed everyone. Speed control and power window placement questionable, cup holder is limited. Like the sport button-whole new car when on. Good daily driver, however, you must miss or slow down for every pot hole and RR Xing. Power top fast enough to put up and down in rush hour. If you buy this car must put a 3M clear bra on ($400). The hood is a rock magnet. Always a head turner. I will come out of a store and always see people looking in. This is my 4th BMW (1 325 xi, 1 325i, and 1 x5) by far the most impractical but ALWAYS the most fun. 35 male-Minnesota

  Love this little car. - 2003 BMW Z4
  By Edmunds Shopper - November 4 - 7:44 am

  Ok. I know its not new, but its totally fun. I love my little car. My friend calls it my go-cart, but thats because hes jealous. It has great pick up when I need to move or go up a hill, I know it will go swiftly. I feel safe in the car. Because its older, it doesnt have a lot of the new technology that newer cars have. No blue tooth or navigation, but I dont need that where I drive. I enjoy getting in my car every day. I get loads of compliments on how the cars style has stayed "in style" and everyone thinks its a new car and is 14 years old! I couldnt be happier with my lil Z4.

  Ultimate Driving Machine - 2003 BMW Z4
  By Dixie Bell - November 3 - 10:00 am

  Have always heard BMWs claims to make the ultimate driving machine. Have never drove one before, but after test driving sports cars for a full year and settling on the Z4, now I know why BMW says that - it is the ultimate truth. This car handles great, takes curves exceptionally well, punch the gas and this car takes off! Interior is extremely comfortable, fuel economy good, especially on long drives. Drove from Alabama to Outer Banks, NC for 5 day trip and everything fit in the trunk - most spacious by far. We go out in the evenings just to drive the Z4 because it truly is fun to drive.

  Bad ass 3.0 - 2003 BMW Z4
  By Jeff P - October 27 - 11:08 am

  I bought this car in May of 2015 with 55,000 miles for only $12,500 ( I now have 62,000 on the odometer). I cannot wait to drive each and every day and wow does the 3.0 automatic ever haul ass. The torque curve is steady throughout the entire ride from 0-100++. No lag, just ferocious power. My only complaint is the amber light cluster for exterior temp and mpg is partially burned out. Also, its very hard to see objects in the rear view mirror due to some peculiar bmw dimming system. Other than that, drop the top and boogie!
