2027 vs. 2026 BMW 3-Series: Specs ComparedBMWThe 2027 BMW 3-series brings one of the world's most iconic sedans into a new generation. Here's how it stacks up with the outgoing model.Now in its eighth generation, the 3-series adopts BMW's Neue Klasse styling, a slightly larger footprint, and a more potent turbocharged 3.0-liter inline-six.According to BMW, the new 3-series is expected to go on sale in the first quarter of 2027. Pricing will be announced closer to the actual launch date.We all grow over time. It's only natural. We spend our first dozen and a half years shooting up like bamboo stalks, before our growth rate slows considerably. Then, we move out on our own for the first time and tack on a few more pounds to be safe. Like the rest of us, the 2027 BMW 3-series, which marks the start of the sedan's eighth generation, has grown once again. Here's a by-the-numbers look comparing the new 3-series (code-named G50) with the outgoing model.As we alluded to, the G50 generation of 3-series sedans has grown by every metric. The new cars are stretched by 1.5 inches from nose to tail, measure 0.9 inch wider, and add 0.3 inch to the roofline. Those changes bring the 2027 3-series up to 187.2 inches long, 72.8 inches wide, and 57.3 inches tall. The wheelbase and track widths have increased as well. The former now stretches 112.6 inches, up 0.4 inch from before.Like a new college student, the 2027 BMW 3-series has also put on a few pounds. BMW lists the curb weight of the rear-drive 330 at 3827 pounds, while adding the xDrive system moves that figure up to 3909. With its larger engine, the M350 xDrive reportedly tips the scales at 4169 pounds. All of those numbers are substantively larger than the previous models that graced our scales. The last M340i xDrive we weighed came in at 3988, while the last all-wheel-drive 330i we tested weighed just 3709 pounds.BMWAt least advanced age generally comes with more refinement. BMW's B48 turbocharged 2.0-liter four-cylinder engine is back for the 330 and 330 xDrive models, though the power curves have changed slightly. The 255-hp peak still arrives at 6500 rpm, but the maximum 295 pound-feet of torque now shows up at 1600 rpm, up from 1550 rpm.At the more powerful end of the lineup, the M340i xDrive is gone, replaced by the M350 xDrive. The B58 turbocharged 3.0-liter inline-six makes its return, though BMW's engineers sourced even more power from the plant for the new M-lite model. While the 2026 and older models generated 386 horsepower, the M350 cranks that number up to 437 ponies at 6500 rpm. Peak torque is up too, rising to 428 pound-feet at 1980 rpm, up from the last gen's 369.Steering should be quicker and more communicative, with BMW giving the new 3-series a new steering ratio, while grip should be up with the M350's optional 275-millimeter-wide rear tires. At some point in the future, BMW promises the new 3-series will get a dedicated drift mode, but as things stand, the new car can already send 100 percent of its torque to the rear axle.On the InsideInterior trappings are new as well. The outgoing 3-series had a well-appointed mix of touch and physical controls. We might have preferred a few more physical switches, but the 12.3-inch digital gauge cluster and 14.9-inch infotainment screens stuck behind one piece of glass did the trick. The new car adopts the same setup as the iX3 crossover with a 17.9-inch hexagonal infotainment screen and an incredibly wide, though incredibly short, display that spans the base of the windshield. The new car also adopts BMW's funky and controversial steering wheel design, which puts spokes at the top and bottom of the wheel.BMWPricing hasn't been revealed yet, but we expect a sizable bump from the current model. According to BMW, the first examples of the new 3-series should start arriving at dealerships in the first quarter of 2027.➡️ Skip the lot.
