Review of the 2008 BMW 3 Series

  • Fully deserving of its popularity, the 2008 BMW 3 Series sets the standard for overall driving enjoyment, luxury and refinement in four different luxury segments. Only its high price will give you pause.

  • Safety
  • Pros

    Perfectly sorted vehicle dynamics, potent and refined engines, high-quality interior materials, wide range of configurations, convertible's sleek retractable hardtop.

  • Cons

    Costs more than most competitors, not much interior storage space, navigation system brings with it exasperating iDrive, plain-Jane interior design.

  • What's New for 2008

    Having introduced two all-new body styles last year, the 3 Series undergoes few changes for 2008. Most notable is the addition of the 335xi coupe, which adds all-wheel drive to the turbocharged 3 Series two-door. Sedans and wagons equipped with the six-speed automatic and Sport Package can now be upgraded with steering-wheel-mounted paddle shifters. The convertible carries over unchanged.

Could hardly be happier

Vehicle: 2008 BMW 3 Series 328i 2dr Convertible (3.0L 6cyl 6M)

Drives like an extension of your body. Top down wind and noise amazingly low and climate control allows you to drive topless in anything but rain. Controls typically Teutonic and not intuitive. Will run decently on less than premium but idle roughens. Love the turning headlights - great on windy roads at night and illumination overall is outstanding. Great highway mileage. Top tends to hang up after being driven with it closed for while, but close/open switch operation allows it to open fine.




Pricey but better

Traded up from previous 04 Saab. Car is best on open road and takes turns like on rails. car not best for city commuting, does not like to go slow and has slow idle speed. Top down car stays toasty with great heat. Pretty soon see how cool it stays with AC on and top down. Did not get sport package and have no harsh ride, think it is the sport tires rather than run-flats that does gives stiff ride.

Vehicle: 2008 BMW 3 Series 328i 2dr Convertible (3.0L 6cyl 6M)

This was my birthday present to myself, I traded in my Z3 that I had planned to keep forever and nearly did. But for my age 2 cars 1 for fun and 1 for practical use doesn't work any longer. This hardtop convertible is the ultimate car for a split personallity girl like me. Practical with room for the groceries or friend, but a joy when the weather comes up right and you want to run to the hills with the wind in your hair.




Wow!

Vehicle: 2008 BMW 3 Series 328i 2dr Convertible (3.0L 6cyl 6M)

Picked up vehicle on Saturday, 3/22 - Comf & Sport. Took the long way home. Acceleration with Steptronic AT was fast & smooth. Love the sound of the throaty engine just before the upshift. You know that you're in a sportscar. The paddle shifters are cool, but I don't suspect I'll use them much on my commute. 328i corned like it was on rails. I took a couple of twisty bends on a backroad at about 60 mph with no sense of skid, roll or fishtail. I had to be careful not to push too hard as the wheels lifted off the ground coming over one little roller. With top down and windows up (38F outside), there was little buffeting of either occupant's hair. Kept warm with heat on auto at 84F.




Fun car

Vehicle: 2008 BMW 3 Series 328i 2dr Convertible (3.0L 6cyl 6M)

My car has everything except the sports package and HD radio. Everything works very well, even the iDrive that people seem to hate. It could be a bit more intuitive, but it is not useless. Real time traffic information isn't very helpful. Navigation works pretty good, but at some intersections, information didn't come soon enough. RFTs make the steering heavier. When I got a nail in one of them, it took several days to get a replacement. Power top mechanism works very well. With the top up, you get a decent cargo space, I think. With the top down, you still have a space enough for a couple of airplane carry on size bags. No mechanical problem so far at 2000 miles.




Great vehicle

Vehicle: 2008 BMW 3 Series 328i 2dr Convertible (3.0L 6cyl 6M)

Upgraded from a 2003 Z4 to the 2008 328 Cabriolet. No regrets whatsoever. Wanted a bit more room than the Z4; and the hardtop convertible for more security, less maintenance, and better sound and cold insulation. For about $6k difference in price, couldn't see the justification for the 335; the 328 has plenty of power.



Full 2008 BMW 3 Series Review

What's New for 2008

Having introduced two all-new body styles last year, the 3 Series undergoes few changes for 2008. Most notable is the addition of the 335xi coupe, which adds all-wheel drive to the turbocharged 3 Series two-door. Sedans and wagons equipped with the six-speed automatic and Sport Package can now be upgraded with steering-wheel-mounted paddle shifters. The convertible carries over unchanged.

Introduction

In the past decade, the BMW 3 Series has been the benchmark against which all other entry-level luxury cars have arguably been designed to compete with and/or beat. To date, a scant few have been able to accomplish the latter. And even when that happens, this Bavarian classic has consistently retaken its crown. Last year saw the addition of a very potent twin-turbo engine and the arrival of fully up-to-date coupe and convertible models. The 2008 BMW 3 Series carries over mostly unchanged and despite fierce competition, retains its benchmark status.

If you're in the market for an entry-level luxury car, chances are there's a 3 Series to consider. There are four body styles, two engines, two transmissions and a choice of rear- or all-wheel drive. Also, a variety of luxury and performance-oriented options allow you to equip the 3 as luxuriously and/or as sporty as you see fit. Regardless of configuration, this BMW lives up to its "ultimate driving machine" tag line with an unparalleled mix of driving ease and proficiency. Even the convertible model manages to retain much of the 3's handling pedigree, despite its added weight and loss of structural rigidity.

In several comparison tests Edmunds.com conducted over the past year, the 3 Series proved over and over again that it's the top dog in the pound -- especially the 335 and its spectacular turbocharged inline-6. We placed the Infiniti G35 Sport above the 335i sedan in one test, but that was due to the substantial price premium commanded by the Bimmer. In fact, the 3 Series' price is its only significant detriment -- a fully loaded 335i sedan can reach $50,000, while the convertible touches 60 large. "Entry level" it ain't.

If price or getting the latest electronic goodies is more important to you, competitors like the Infiniti G35/G37, Cadillac CTS, Mercedes-Benz C-Class, Audi A4 and Volvo C70 are very attractive competitors. Even when discussing driving enjoyment, most deliver at a level that many consumers will find extremely rewarding and downright fun. Still, the 2008 BMW 3 Series remains the benchmark. As always, it provides a tremendous mix of handling, ride quality, performance, luxury and styling. Heck, it's even pretty fuel efficient. For an entry-level luxury car, this is our top choice.

Body Styles, Trim Levels, and Options

A compact entry-level luxury car, the 2008 BMW 3 Series is available in sedan, coupe, hardtop convertible and wagon body styles. All come in a rear-wheel-drive 328i trim level, while the coupe, sedan and wagon also come in all-wheel-drive 328xi trim. In addition, the convertible, coupe and sedan are available as the rear-drive 335i, and the sedan and coupe are available as the all-wheel-drive 335xi.

Standard equipment on the 328 models includes 16-inch alloy wheels, heated side mirrors, a sunroof, leatherette upholstery, real walnut wood trim, automatic climate control and a 10-speaker CD stereo with an auxiliary audio jack. Coupe and convertible versions of the 328 come with slightly more equipment. The coupe also has a sport-tuned suspension while the convertible has a power-retractable hardtop. In addition to its more powerful engine, the 335 model has power front seats and a premium Harman Kardon Logic 7 sound system.

Most 3 Series cars you encounter on dealer lots will be equipped with the Premium Package, and many will have both the Premium and Sport Packages. The Premium Package provides leather upholstery (heat-reflective in the convertible), a full set of auto-dimming mirrors, Bluetooth, BMW Assist telematics, and on 328 models, power seats. The Sport Package specifies a firmer suspension on convertibles, sedans and wagons, along with larger wheels, performance tires, sport seats and a higher top-speed limiter.

Stand-alone extras include an iDrive-based navigation system with real-time traffic updates, active steering, adaptive cruise control, keyless startup (known as Comfort Access), heated front seats and satellite radio. Paddle shifters can be added to models equipped with the automatic transmission and the Sport Package. You can also replace the standard walnut interior accents with either light poplar or aluminum trim at no additional cost.

Powertrains and Performance

The 2008 BMW 328i and 328xi are powered by a 3.0-liter inline-6 rated at 230 horsepower and 200 pound-feet of torque. The 335i and 335xi are powered by a heavily modified, twin-turbocharged version of the same 3.0-liter engine that produces an impressive 300 hp and 300 lb-ft of torque. A six-speed manual is the standard gearbox and a six-speed automatic is optional. In performance testing, the turbocharged 3 Series sedan and coupe raced up to 60 mph in fewer than 5 seconds -- about the same as the last M3. The heavier 335xi and convertible 335i are a tad slower. Expect the 328i to be in the mid-6-second range, which is hardly pokey.

Despite its potent power plants, the 3 Series remains fuel efficient. The 328 gets about 17-18 mpg in the city and 25-28 mpg on the highway, depending on the body style, transmission and drivetrain. A rear-drive 335i has a 17/26 mpg rating regardless of transmission.

Safety

Standard safety equipment on the 2008 BMW 3 Series includes antilock disc brakes, dynamic brake control, stability control, run-flat tires, front-seat side airbags and full-length side curtain airbags. The convertible lacks the side curtains, but the regular front side airbags extend up to head level and there are also pop-up rollover hoops. The stability control system integrates several features designed to improve braking performance, such as periodically wiping the brake rotors when the windshield wipers are in use (wet brakes don't stop so well) and snugging the pads to the rotors when the driver abruptly lifts off the throttle, which quickens brake responsiveness.

In government crash tests, the sedan and wagon received four out of five stars for frontal collision protection and five stars for side protection. In Insurance Institute for Highway Safety frontal-offset crash testing, both the sedan and convertible received the highest rating of "Good." In the IIHS side crash test, the sedan received a "Good," while the convertible received a third-best "Marginal" rating.

Interior Design and Special Features

The 3 Series interiors provide a restrained show of luxury. Though a tad plain, the emphasis, through items such as supportive seats and clean analog gauges, is on driver comfort and involvement. Materials are high in quality and build quality is exceptional; indeed, even the standard leatherette (vinyl) upholstery looks and feels better than one would expect. The convertible's available industry-first heat-reflective leather does a wonderful job of keeping occupants' posteriors cool. We'd steer clear of the optional navigation system, though, as its accompanying iDrive interface is very unintuitive.

The front seats have enough firm support to ward off fatigue during a day's worth of driving, while the rear seats are adequately roomy for adults on shorter trips and plenty accommodating for children. Trunk space is average in sedans and coupes, while the wagon offers a maximum cargo capacity of 61 cubic feet. The convertible offers a reasonable cargo hold when the hardtop is up, but it shrinks considerably when the top is lowered.

Driving Impressions

There's no going wrong with either of the engines available in the 2008 BMW 3 Series. The standard, normally aspirated engine is a little light on low-end torque, but it moves the car around smartly and provides slightly better mileage. Meanwhile, the twin-turbo engine provides the kind of acceleration formerly associated with the high-performance M3.

No matter which model you choose, the 3 Series' world-class suspension, steering and brakes will provide hours of entertainment on twisty two-lane highways. Beyond simply feeling rock-solid when hustled around turns, this car communicates with the driver in a manner that inspires confidence no matter what kind of driving you're doing. At the same time, the 3 Series is an ideal long-distance cruiser, delivering both a comfortably controlled ride and a quiet cabin environment.
