Unleashing the Beast: 2025 BMW X3 M50 Ditches 'i' for Unrivaled Power
The automotive world has always been captivated by the unique blend of performance and luxury that BMW delivers. This time, BMW has opted not to follow their traditional release pattern. For the fourth-generation X3, also known as the G45, BMW brings forth the M50 right out of the gate, skipping the usual wait. Crucially, this new variant drops the 'i', making way for the name to signify a significant bump in power, defying the industry trend of downsizing engines.
Under the hood, the first-ever X3 M50 retains BMW's acclaimed B58 engine, now paired with a mild-hybrid setup. This blend of the turbocharged 3.0-liter engine and an electric motor yields a total system output of a thrilling 393 horsepower and 428 lb-ft of torque. The internal combustion engine contributes 375 hp and 398 lb-ft, while the crankshaft-mounted starter generator adds another 17 hp and an astonishing 147 lb-ft.
Cranking Up the Power: X3 M50 vs. X3 M40i
The X3 M50 significantly outruns its predecessor, the X3 M40i. The retired M40i offered 355 hp and 369 lb-ft of torque in Europe, making the M50's upgrade of 38 hp and 59 lb-ft highly notable. U.S. models also benefit from this performance hike, enjoying an extra 11 hp and 59 lb-ft over the previous X3 M40i editions sold stateside. Unlike various other models that face different specifications based on regional emissions regulations, both European and American X3 M50 models enjoy identical power outputs this time around.
Furthermore, an integrated e-motor in the eight-speed automatic transmission allows the X3 M50 to catapult from 0 to 62 mph in a mere 4.6 seconds, making it 0.3 seconds faster than the Euro-spec X3 M40i that preceded it. For the U.S. audience, the sprint to 60 mph is completed in a quick 4.4 seconds. Despite the power boost, the top speed remains electronically capped at 155 mph, matching the previous generation.
A Revolution Under the Hood
The X3 M50 is now the sole six-cylinder X3, as well as the only M Performance version, following the demise of the M40d. This model carries the most powerful inline-six engine ever placed in a BMW M Lite car. The B58B30M2 engine operates on the advanced Miller cycle and showcases comprehensive revisions—from its injection system and crankshaft to an eVANOS electrically controlled camshaft adjustment. Optimized oil supply and an enhanced turbocharger ensure this powerhouse performs seamlessly, inhaling and exhaling through a new quad-pipe exhaust system.
Meet the Meaner Machine
BMW didn't just stop at overhauling the engine; the X3 M50 flaunts an aggressively redesigned front grille. Setting it apart from lesser X3 models, the 'kidneys' feature horizontal slats situated above sizable air intakes. Standard 20-inch alloy wheels anchor the vehicle, although enthusiasts can opt for even larger 21-inch or 22-inch rims for an enhanced road presence. The new model also boasts flat-bottomed steering wheels, sports seats wrapped in Veganza (an artificial leather) and Alcantara, and a conspicuous red 12 o'clock mark, adding to the interior's sporty character.
Mark Your Calendars
The 2025 BMW X3 M50 is set to roll out of BMW’s Spartanburg facility starting September 2024, with its market debut slated for the fourth quarter of the year. Priced at $64,100 in the U.S., plus $1,175 for destination and handling, the X3 M50 demands a $2,380 premium over the retiring X3 M40i. In addition to the U.S., Germany has been listed as one of its principal markets.
Looking further into the future, enthusiasts can expect a full-fledged X3 M, rumored to carry the 'ZA5' codename. However, rather than following the conventional CLAR platform, this new model would likely debut as an electric variant based on BMW's Neue Klasse platform, possibly arriving around 2028. Until then, the X3 M50 promises to satisfy performance cravings with its unparalleled power and aggressive styling.
