KBB Editors' Overview
By Matt Degen - Updated Date: 4/24/2014
Introduced last year, the BMW 4 Series is a newer model line with a familiar concept: essentially, 2-door versions of the 3 Series. The fresh nomenclature sets the 4 Series coupe and hardtop convertible apart from the growing variety of 3 Series models, though for 2015, the 4 Series itself is expanding with the introduction of the Gran Coupe, a 4-door meant to look sleeker than a traditional sedan. While the 2015 4 Series range is growing, the lineup retains the powerful engine choices, excellent driving manners, innovative technology and sporty styling inherent to BMW. Like luxury rivals such as the Audi A5, Mercedes-Benz C-Class coupe and Cadillac ATS coupe, the 4 Series adeptly blends performance and refinement to go with its $40,000-plus starting price.
You'll Like This Car If...
If you crave the excellent handling and power of the 3 Series sedan in coupe or convertible form, look to the 2015 BMW 4 Series. The new 4-door Gran Coupe is the only 4 Series with room for five, and is able to carry cargo easier, thanks to its wide-opening liftgate.
You May Not Like This Car If...
If a comfortable ride takes priority to sharp handling, the Mercedes-Benz C250 or Cadillac ATS coupes may better suit your taste. It should also come as no surprise that rear-seat space in the coupe and convertible is tight – which is where the 4-door Gran Coupe comes into play.
What's New for 2015
This year marks the debut of the 2015 M4 coupe and convertible, and the new 4 Series Gran Coupe. The former models pack a roaring 425-horsepower engine and other performance upgrades, while the latter is a 4-door model with more cargo room and passenger space.
The 2015 4 Series takes the performance traits of the BMW 3 Series – agility, acceleration and overall balance – and goes one better. With a wider stance and lower center of gravity, 2-door versions of the 4 Series are the perfect partner if you enjoy throwing your car into a corner. Tradeoffs are noticeable road noise and a stiff ride on rough pavement. The roomier Gran Coupe excels at grand touring thanks to its lively yet smooth road manners and extra cargo capacity. 428i models employ BMW's excellent 240-horsepower 4-cylinder engine to power the rear or all four wheels. Though it's turbocharged, not a hint of lag is felt, even in "comfort" mode. 435i models use a 300-horsepower 6-cylinder that can propel all-wheel-drive models to 60 mph in 4.7 seconds. Transmission choices – an 8-speed automatic or 6-speed manual in 428i and 435i coupes – are exceptional. Packing 425 horsepower, the BMW M4 performance coupe and convertible can hit 60 mph in about four seconds.
2.0-LITER TURBOCHARGED 4-CYLINDER ENGINE
The base engine in the 4 Series is so good that it leaves little reason to pay thousands more for the 6-cylinder variant. Beyond its impressive specs – 240 horsepower, 255 lb-ft of torque, up to 35 mpg on the highway – is its immediate responsiveness.
As with other BMWs, the 2015 4 Series includes four years/50,000 miles of free factory-scheduled maintenance. That means oil changes, brake pad and disc replacement, drive-belt maintenance and more are covered. BMW tallies the savings at up to $2,000. We laud it for the peace of mind.
