BMW M340
The BMW M340 brings an ideal blend of the 3 Series practicality and the brand's M performance line. The sporty four-door sedan is available in rear-wheel drive or xDrive all-wheel drive, and it offers many of the M components while remaining more affordable than the more performance-packed M3–think of it as M3 light. The M340i features M Sport seats, M Sport brakes, and a more aggressive look than the standard 3 Series. It may not have the M3's horsepower, but with 386 horsepower on tap, it's just as quick as the base M3.

First generation BMW M340
Shortly after the current-generation 3 Series arrived in 2019, BMW introduced the all-new M340i, ideal for the 3 Series shopper who wanted the added performance without taking the step up to the ultimate-performance M3. A considerable upgrade over the 340i it replaced, the M340i arrived with a turbocharged 382-horsepower engine and either rear- or all-wheel drive. According to BMW, the current M340i xDrive (now with 386 horsepower) can reach 60 mph in 4.1 seconds, the same as the base M3.
While it delivers impressive performance, the M340i is priced thousands of dollars lower than the M3. But it still delivers all the amenities and tech features expected of a high-end BMW 3 Series. The M340i originally arrived with a 10.25-inch display, but with the 2023 refresh, the interior was updated with a curved screen encompassing a 14.9-inch screen and a 12.3-inch digital gauge cluster. While it is available with niceties like leather trim and heated seats, surprisingly, many advanced driver-assist features, like adaptive cruise control, don't come standard.
