Pros

If you’re seeking a midsize-performance sedan with an unquestioned reputation for performance, quality, luxury and safety, the 2018 3 Series from BMW checks all the right boxes. The Gran Turismo hatchback and 3 Series Sport Wagon offer impressive versatility, while the plug-in hybrid and diesel models deliver superior fuel economy.

Cons

The 2018 BMW 3 Series comes at price, especially when adding optional equipment often found standard on its competitors. The Cadillac ATS is an impressive performer in its own right, as is the Infiniti Q50. Even the new Jaguar XE is distinct enough to lure away potential BMW buyers.

What's New?

The BMW 3 Series for 2018 receives a new touch-screen display that works in conjunction with the iDrive controller. Also new is a standard rearview monitor and LED headlights. On 320i models, LED fog lights replace traditional fog lights.

For over 40 years, the BMW 3 Series has been the car that best demonstrated BMW’s long-running slogan, “the Ultimate Driving Machine.” In the 2018 BMW 3 Series sedan, the legend continues unabated albeit in a larger, more luxurious and more powerful version. The current 3 Series lineup competes head-on with the Audi A4, Infiniti Q50 and Cadillac ATS. Yet, as good as the competition is, none has ever been able to capture that perfect balance of luxury, performance, power and styling in quite the same way the 3 Series does. One thing that has changed is the range of models. For 2018, the Series now includes a plug-in hybrid, sporty wagon, versatile hatchback, and the incomparable 2018 BMW M3 high-performance sedan (reviewed separately).

2018 BMW 3 Series Pricing

2018 BMW 3 Series pricing starts at $13,190 for the 3 Series 320i Sedan 4D, which had a starting MSRP of $36,995 when new. The range-topping 2018 3 Series 340i Gran Turismo xDrive Sedan 4D starts at $25,643 today, originally priced from $58,245.

The Kelley Blue Book Fair Purchase Price for any individual used vehicle can vary greatly according to mileage, condition, location, and other factors. The prices here reflect what buyers are currently paying for used 2018 BMW 3 Series models in typical condition when purchasing from a dealership. These prices are updated weekly.

Driving the BMW 3 Series

Above every other aspect, the 2018 BMW 3 Series sedan, hatchback and wagon place an emphasis on driving pleasure. It’s been the brand’s calling card for nearly four decades and neither time nor technology has gotten in the way. Speed and agility are standard on every model, and even the base 320i with only 180 horsepower can hit 60 mph in 7.1 seconds. Similar performance can be found in the 328d diesel, which affords the added benefit of a 40-mpg highway rating. Moving to the 248-horsepower turbocharged 2.0-liter 4-cylinder gasoline engine in the 330i brings what we think is the best combination of performance and price, while the 320-horsepower 340i delivers V8-like power and growl. For those seeking the elusive M3, it’s a track-ready terror whose dual-clutch automatic doesn’t quite live up to the car’s promise. Go with the manual.

Interior Comfort

BMW interiors are never overly ornate and the interior of the BMW 3 Series is simple, elegant and minimalistic in design. It’s also beautifully assembled with tight fits and upscale materials. Seat comfort is exceptional as is the driving position. The gauges are clear and concise. The center controls are angled toward the driver, putting them in easy reach. The sedans have acceptable legroom in the second row, and it’s downright impressive in the larger 3 Series Gran Turismo. The Sports Wagon and Gran Turismo models offer sizable cargo-hauling advantages over sedan-only rivals like the Lexus IS and Mercedes C-Class.

Exterior Styling

This is simply one of the most attractive cars on the road. With short overhangs and a low, wide stance, BMW’s 3 Series for 2018 just looks athletic. It looks like it’s fun to drive. It’s a completely modern design, but there are enough links to previous generations, including the signature twin-kidney grille, that even casual observers know they’re looking at a BMW. The more rotund Gran Turismo is an acquired taste, while the Sports Wagon is universally admired, and the bulging, scooped and flared skin of the macho M3 hints at the potency below its domed hood.

Favorite Features

WAGON, HATCH VARIANTS
While the most recognizable 2018 3 Series is the sedan, BMW also offers a versatile hatchback called the Gran Turismo and a sporty all-wheel-drive Sports Wagon. Both models offer a more versatile cargo area without compromising 3 Series ride and handling.

TURBOCHARGED 4-CYLINDER
While there are many 2.0-liter turbocharged engines in the world, none is quite as smooth, refined or powerful as the engine found in BMW’s 2018 3 Series. The 248-horsepower engine is capable of propelling the 3 Series to 60 mph in under six seconds, yet achieves a respectable 34-mpg highway.

Standard Features

At its most basic, 320i models come with BMW’s faux-leather upholstery (SensaTec), manually adjustable front seats, rain-sensing wipers, dual-zone climate control, a 9-speaker audio system with a 6.5-inch LCD display, USB port, Bluetooth music streaming and HD Radio. Safety features standard on every 2018 BMW 3 Series include eight airbags, active head restraints to help reduce the severity of whiplash injuries, and impact sensors that unlock the doors, activate the hazard lights, and shut down electrical systems after a collision. New BMWs also include four years/50,000 miles of no-cost scheduled maintenance and four years/unlimited miles of roadside assistance.

Factory Options

Options on the 2018 3 Series are extensive and pricey. However, many are worth the investment, including the Surround View camera, a hands-free power trunklid that opens by waving your foot under the bumper, navigation, a head-up display, and adaptive cruise control. The sport seats, aerodynamic enhancements, suspension tuning, and lightweight wheels of the M Sport Package (standard on the 340i) help bridge the performance gap between lesser models and the fire-breathing M3. All-wheel drive (AWD) is available on many models in lieu of rear-wheel drive (RWD), although not on the M3, and is standard on the Sports Wagon and Gran Turismo.

Engine & Transmission

The 2018 BMW 3 Series lineup offers three 4-cylinder turbocharged engines: a 2.0-liter in the 320i, a more powerful version in the 330i, and a 2.0-liter turbodiesel. Then there’s the new turbocharged 3.0-liter inline-6 in 340i models, and the twin-turbo version in the M3, which makes 425 horsepower. Most models can be ordered with a 6-speed manual transmission or an 8-speed automatic. The M3 comes with the manual or a 7-speed dual-clutch automatic. New last year was the 330e plug-in hybrid, which pairs an electric motor and a turbocharged 4-cylinder for 25 miles on battery power alone or total range of 373 miles. Most 3 Series models come with a fuel-saving stop/start feature. Unfortunately it shudders when the engine restarts and thankfully can be deactivated.
