Surprise! This BMW 3 Series Packs a 550-HP V10 Engine
Everyone likes a good “sleeper.” No, not those tractor trailers with extra space for catching some shuteye—sleepers; cars that look fairly innocuous from the outside but pack a brutal punch of power within. These automotive oddities span the gamut from unsuspecting Buick LeSabres to Viper-crushing minivans, and everything in between. And although BMW commands a significant performance vibe, one could even argue the sleeper status of this car—a 2006 BMW 325i. When new, the zippy BMW would have netted 215 horsepower from its 3.0-liter straight six—peppy, but not earth-shattering. Today, it swallows the V10 engine from a BWM M5. Yikes. This is one BMW 3 Series you won’t want to mess with.
In an interesting twist, this manic 325i hails from Germany…but by way of the USA. According to the vehicle’s owner on eBay, this BMW 3 Series was sent back across the Atlantic to renowned tuner Hartge, which outfitted the car with one of its exclusive H50 packages. The kit includes a laundry list of performance additions, including a new limited-slip differential, quad exhaust, and a seven-speed gearbox, but the most prominent is undeniably that M5 V10 (from the E60 series).
Thanks to engine tuning by Hartge, the BMW V10 erupts with a colossal 550 horsepower and 391 lb-ft of torque, capable of an alleged run to 60 mph in 4.3 seconds and a top speed of 200 mph. Talk about a stoplight brawler. Thankfully there are truly massive 13- and 15-inch brakes behind those wheels to provide deceleration.

Only ten are said to have been built in entirety, making this V10 monster quite the rare bird. So what does it take to build a car like this? A claimed $220,000 through Hartge including the car, circa 2006. Today it requires significantly less coin for the keys—$127,500—though even for that price you’re up against some pretty stiff competition, including BMW’s less expensive and more modern 575-horsepower M5.
However, you certainly won’t have to worry about running into another one at the local shopping center. This Hartge is said to be the only one of its kind on U.S. shores, and we’d believe it.
