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.

  Best of the Best! - 2010 BMW Z4
  By rmorin49 - March 18 - 9:17 pm

  I ordered my Z4 for European Delivery and enjoyed my trip to Munich and the new BMW Welt. The car is absolutely awesome, 6 speed manual tranny has a short throw, well spaced gears and makes the car more like a classic roadster. With the hardtop up it is a weather tight coupe. Styling is incredible inside and out. Sport seats are very comfortable. Trunk has enough room for a good sized suitcase even with the top down. This is my 8th BMW and may well be my favorite. Car gets lots of thumbs up from all ages. It is the best looking sports car sold in the US under $60K.

  One is not enough - 2006 BMW Z4
  By DaveTwinZs - February 11 - 9:56 am

  I bought my first Z4 in the spring of 2009. My wife and I argued as to who would drive it, so I bought another last fall. No doubt, fun to drive, scary quick, and either a head turner. BMWs reputation for service is second to none. I agree with many people here. If you want to get happy quick, go start and drive a Z4!

  Best luxury sports car ever - 2010 BMW Z4
  By mat man - February 9 - 5:12 pm

  I traded in a 2005 Z4 and there is no comparison, also own a Miata which is a toy. This car is great for highway driving as well as running around country roads in the sports mode. This car is much more civilized then the much touted Porsche boxter. I could have purchased the Porsche for the same money to me there was no contest. This car is totally redesigned. Wherever i go people stare at this beautiful machine. I love to drive it.

  Z4 is a blast! - 2005 BMW Z4
  By Z4eeaahh - February 8 - 2:34 am

  Wow! The Z4 is pure driving excitement! The vehicle has opened up the world of weekend roadtrips for me, but instead of using the GPS, I find myself reading a map to determine an alternate route to my destination. The highways are fun, but the Z4 really shines on the back roads. Some words that come to mind to describe this vehicle are responsive, tight, nimble, classy, smooth and deceivingly quick. Do not expect a luxury ride from the Z4, but expect to feel the road. It is a performance vehicle. That being said, I am 62" and once in the vehicle I am quite comfortable, even on long road trips. I am guaranteed a smile every time I take my Z4 for a drive. :-)

  Nice but not for me - 2006 BMW Z4
  By Midlifemom - February 2 - 10:20 pm

  I bought this Z4 two years ago and only drive it 6000 miles a year. The seats are uncomfortable despite their quality, and the shifter/armrest arrangement causes one to slurp to the right while driving- ends up uncomfortable. Vision is not good on Left. Wonderful car, so very beautiful, but harsh on the highway with run flats. Runs like the wind, hits 100 right away. Chippy in the tracks on the interstate, enormous blind spot, not easy to back up. Just not comfortable enough for a daily driver or frequent driver. Reliability superb, but I have to crawl out of it. When I saw it, I simply had to have it, then never drove it much and it just sat in the garage. Nice, but think twice.

  SO much fun!! - 2009 BMW Z4
  By BMW Addict - January 26 - 1:46 pm

  Just purchased the re-designed Z4. I have owned three Z4s, kept trying to talk myself into liking the previous version, to no avail. The new Z4 is a winner. The interior is roomier both in length and width, which is great for my 6 frame. The 3.0 has plenty of power. The only options I got were auto and heated seats. The body is rigid but not abusive when driving. Easily a commuter car. The styling is flawless - be prepared for people staring at you. If you can find an 09, grab it, BMW is giving a $5000 cash rebate if you finance. Mine had a sticker of $49k and I got it for $39,300!! Cant wait for summer! I turned in a Lexus IS250 Vert - Lexus = fun to RIDE in, BMW = fun to DRIVE!!

  Remake this Classic - 2006 BMW Z4

  WOW - 2005 BMW Z4
  By RXZ4 - January 20 - 12:06 am

  WOW and to think we waited over three years to finally find and purchase our dream machine. 05 with 22K, CPO and extended maintenance plan, and fully loaded. The tires are pretty sensitive to less than perfect roads and youll find yourself driving with two hands on the wheel. We actually like the cup holders and the radio rocks!

  Love my car - 2007 BMW Z4
  By Fastcar - January 14 - 6:41 pm

  Im having the time of my life driving this car. Im a short (53") female and this is the first car that I feel I really fit in. It looks fabulous, drives great and has provided the best driving experience Ive ever had. Ive taken it on 2 road trips (one 500 miles, and the other 700 miles) and was amazed at how my back didnt hurt after. My only heart burn is the large lease payment that I make every month.... other than that its great!

  The Good and the Bad - 2003 BMW Z4
  By Jason Y. - January 3 - 12:49 pm

  Shortly after purchasing it used at 59,200 miles, the coolant light came on so I filled it up when the engine was cold and it continues to leak whenever the coolant expands with a hot engine. Im guessing the coolant expansion tank is cracked. Other than the above mechanical issue this car draws a lot of semi-truck drivers attention and praises and other people on the road also. It feels like this car has sticky glue on the tires during fast turns. Manual 6-speed transmission shifts wonderfully. Not the fastest car on the road against say a Ford 500GT or any other hot rods but this Z4 has the right balance between styling and performance.
