Over the past four decades, BMW’s iconic 3 Series has set the standard for style, performance and luxury. The 2018 BMW 3 Series builds on that excellent reputation with hatchback, plug-in hybrid and wagon variants.
The base 2018 BMW 3 Series is a midsize luxury sedan that seats five. It’s offered in 320i, 328d, 330i, 330e and 340i trim levels. Rear-wheel drive is standard, while BMW’s all-wheel-drive system (xDrive) is available. The 3 Series is also as a wagon (330i xDrive Sports Wagon) and as a four-door hatchback (330i xDrive Gran Turismo and 340i xDrive Gran Turismo). Turbocharged four-cylinder and six-cylinder engines are offered. BMW also offers hybrid and diesel power plants. The high-performance 2018 BMW M3 is covered in a separate review.
For 2018, the 3 Series receives an updated infotainment system with a touch screen. Other additions for the model year include a standard rearview monitor and LED headlights.
BMW’s 3 Series is a modern interpretation of the brand’s storied sedan. The use of BMW’s kidney grille is front and center. The “Hofmeister Kink” bends the C-pillar back toward the rear door area. This subtle styling cue can be found on every BMW for the past 50 years. The short overhangs and low stance hint at the vehicle’s performance. Like an Olympian in a tailored suit, the 3 Series looks athletic and refined.
The base 320i includes LED headlights, LED fog lights and 17-inch alloy wheels. Rain-sensing windshield wipers and automatic headlights add convenience. Power-adjustable side mirrors and non-metallic paint also are standard.
Options include metallic paint, a blacked-out grille and M styling features. BMW also offers an aerodynamic package, adaptive headlights and unique 18- and 19-inch alloy wheels.
The 2018 BMW 3 Series interior is purposeful, yet attractive. BMW’s formula favors simplicity over gimmicks. Materials are high quality. Fit and finish are exemplary. The result is a well-thought-out design that yields excellent driver ergonomics. The front seats offer plentiful headroom and legroom. The standard tilt-and-telescopic steering column allows most individuals to find a comfortable driving position. Gauge and control placement is thoughtful and intuitive.
BMW 3 Series standard features include a multi-function steering wheel, leatherette upholstery, dual-zone climate control, manually adjustable seats and interior ambient lighting. The standard leatherette upholstery is comfortable and long-wearing. The satin silver matte trim complements the interior.
The rear seating in the sedan is adequate. Two adults fit, and the sedan can accommodate three adults for short rides. The Gran Turismo model adds valuable legroom for rear-seat passengers.
The 3 Series sedan offers 13 cubic feet of cargo space. That’s equal to what you’ll get with the 2018 Audi A4, and it’s slightly more space than the Mercedes-Benz C-Class offers. The 330i xDrive Gran Turismo hatchback offers 24.6 cubic feet that is expandable to 56.8 cubic feet when the second-row seats are folded. Those looking for the most cargo space will want to investigate the 330i xDrive Sports Wagon. The wagon’s cargo area offers 27.5 cubic feet and grows to 61.5 cubic feet.
Interior upgrades include a heated steering wheel, heated power-adjustable front seats and heated rear seats. Rear manual window shades, stainless steel pedals, wood trim and an anthracite headliner also are available.
The 2018 BMW 320i is powered by a turbocharged 2.0-liter four-cylinder engine rated at 180 horsepower and 200 pound-feet of torque. The 330i variants receive a more powerful version of the turbo four-cylinder that makes 248 horsepower and 258 pound-feet of torque. The 340i boasts a turbocharged 3.0-liter inline six-cylinder engine that creates 320 horsepower and 330 pound-feet of torque. The 340i Gran Turismo is powered by the same displacement engine, but it churns out 300 horsepower and 300 pound-feet of torque. The 3 Series can be ordered with a six-speed manual or an eight-speed automatic transmission. Rear-wheel drive is standard on the sedan. All-wheel drive is standard on the Gran Turismo and Sports Wagon, and available on the sedan.
BMW also offers the 3 Series with diesel power. The 328d is powered by a turbodiesel 2.0-liter four-cylinder engine that generates 180 horsepower and 280 pound-feet of torque. The final option is BMW’s hybrid-powered 330e iPerformance sedan. The 330e is powered by a turbocharged 2.0-liter four-cylinder engine and an electric motor. Total system power comes in at 248 horsepower and 310 pound-feet of torque.
The turbocharged four-cylinder-powered 3 Series sedan is rated at up to an EPA-estimated 24/35 mpg city/highway. Models with the six-cylinder engine are rated at up to 21/32 mpg city/highway. The hybrid model achieves 30 mpg combined. While all 3 Series models are fuel economy leaders in the segment, the diesel earns the best numbers. At up to 31/43 mpg city/highway, the 328d is tops around the city and on long stretches of the highway.
The base 2.0-liter turbo four-cylinder provides adequate acceleration, but it is the overall driving dynamics that make the 3 Series a wonderful car on the road. BMW bills itself as building “the ultimate driving machine,” and the 3 Series is arguably its best representative. Engine power is not the only factor in building a great car. Steering is precise. Braking is above average. The suspension is comfortable but tuned for performance. Moving into the more powerful engines only adds to the satisfaction and fun.
The 2018 BMW 3 Series features one-touch windows, cruise control and push-button start. The 3 Series’ standard infotainment system features a 6.5-inch color display, a nine-speaker Bose audio system, Bluetooth, USB connectivity and HD Radio. The basic system is controlled with BMW’s iDrive system. Learning the system takes a little time, but it is intuitive. For 2018, BMW adds touch-screen controls to the system. Unfortunately, BMW’s decision to make Apple CarPlay optional and not to include Android Auto feels out of place in the segment. Only including one USB port also holds back an otherwise great setup.
Available infotainment upgrades include a Harman Kardon surround sound system, navigation, wireless charging, Wi-Fi, a head-up display and satellite radio.
The 3 Series now includes a standard rearview camera. Available safety technology features include forward automatic braking, parking assist and forward collision warning. Front and rear parking sensors, lane departure warning and blind-spot monitoring are also optional.
The 2018 BMW 3 Series starts at $34,900 for the base model 320i. The least expensive all-wheel-drive model is the 320i xDrive, which starts at $36,900. The turbocharged six-cylinder-powered 340i is $48,950. Diesel models start at $41,750, and the hybrid begins at $45,600. The 330i xDrive Sports Wagon costs at least $45,000. The 330i xDrive Gran Turismo is $45,400. These prices do not include a $995 destination charge.
The base 320i is the cheapest way into the 3 Series family and represents great value in the segment. It lacks the acceleration you’ll get with one of the six-cylinder powerplants, but that does not keep the 320i from qualifying as one of BMW’s “Ultimate Driving Machines.” The steering is precise, and the handling is superb. We would add the $3,550 Sport Plus option that includes 18-inch wheels, M seats and M Sport suspension to enhance the driving dynamics. For safety, we would include the $500 Driver Assistance package. Finally, we would opt for the $2,250 Convenience package and the $3,000 Premium package for added luxury. The packages are referred to as the Premium Tier and include a moonroof, heated power-adjustable front seats with lumbar support, satellite radio and navigation. The total amounts to $42,945, plus destination.
The 2018 BMW 3 Series continues to be a leader in the midsize luxury sedan segment. The base 320i is affordable and fun to drive. BMW’s 3 Series Gran Turismo hatchback and the Sports Wagon add family-friendly convenience and utility. The turbodiesel and hybrid models enhance the 3 Series’ already excellent fuel efficiency.
