The 2027 BMW 3-Series marks a strategic shift in the manufacturer's lineup, launching alongside the battery-powered i3 but operating on entirely separate platforms. Unlike previous generations where powertrains shared engineering foundations, the combustion 3-Series and the electric i3 are now built at different facilities; the new sedan is assembled in Dingolfing, Germany, while the i3 is produced in Munich. This separation allows the internal combustion models to be evaluated on their own merits without compromise. The lineup includes the entry-level 330, available in rear-wheel drive or xDrive all-wheel-drive configurations, and the performance-oriented M350 xDrive. Notably, the traditional "i" suffix has been removed from model names as it now serves as a prefix for electric vehicles.
Physically, the new generation exhibits modest growth across its dimensions. The wheelbase has increased by 0.4 inch to 112.6 inches, length by 1.7 inches to 187.6 inches, and width by 0.9 inch to 72.8 inches. Height has risen slightly to 57.3 inches, largely attributed to the larger rolling diameter of the new standard 19-inch and optional 20-inch tires. However, these dimensional changes come with an estimated weight gain of roughly 200 pounds, placing the M350 xDrive near 4,200 pounds. The exterior design fully embraces BMW's Neue Klasse styling, characterized by a forward-leaning grille that stretches across the front end and blends into the headlights. Despite the aggressive front fascia, the vehicle retains long-hood proportions necessary for its inline-six engine, paired with squared-off flanks and a cabin set rearward over a trunk offering 16 cubic feet of cargo space.
Under the hood, both engines utilize the Miller cycle to optimize air-fuel ratios and feature switchable exhaust valves to reduce engine braking, thereby maximizing energy recovery for the 48-volt hybrid-assist system. The 330 model maintains its previous output of 255 horsepower and 295 pound-feet of torque while meeting stricter European emissions standards. The M350 xDrive sees a substantial upgrade, featuring reshaped intake ports, revised camshaft timing, and a larger turbocharger that boosts power to 437 horsepower and 428 pound-feet of torque. This increase is expected to improve the 0-60 mph time by approximately two-tenths of a second compared to the outgoing M340i xDrive.
Chassis updates include a wider front subframe and refined dual-link strut suspension geometry with increased caster angles and adjusted static negative camber to enhance on-center feel. All models feature stiffer anti-roll bar mounts and optimized rear bushings for improved passive steering characteristics. The base dampers have been updated with hydraulic rebound stops rather than springs. In testing the M350 xDrive in southern France, reviewers noted that the retuned Adaptive M suspension offers a more dynamic yet comfortable ride. Additionally, revisions to the M Sport differential and xDrive torque-split allow the vehicle to maintain its line even when entering corners at high speeds.
The interior introduces the Neue Klasse driver interface, headlined by a 17.9-inch angled touchscreen and Panoramic Vision instrument displays projected across the base of the windshield. While the front seats are described as supremely comfortable and rear space has improved over the previous generation, knee room remains tight for taller passengers behind the driver. The cabin features a Harman/Kardon stereo with Dolby Atmos support but lacks fixed buttons for many functions, requiring users to navigate touchscreen submenus for adjustments like air vents. As a Software Defined Vehicle (SDV), the car will receive over-the-air updates, including a "Drift Moment" feature that diverts power to the rear wheels and a Highway Assistant capable of hands-free driving up to 85 mph on limited-access highways.
The 2027 BMW 3-Series is scheduled for release near the end of the first quarter of 2027. Pricing starts at $51,250 for the base 330 model, rising to $53,250 for the 330 xDrive, and reaching $67,250 for the M350 xDrive.
