First Look: Hartge Tunes BMW's X1 Diesel Crossover
Although M GmbH has seen fit to tune a number of BMW's crossovers, it's somewhat unlikely that BMW's performance wing will spit out a hopped-up version of the X1, especially in diesel form. No matter; German tuner Hartge has already treated the diesel CUV to a mild cosmetic and performance makeover.
Additional power comes courtesy not from a long list of mechanical modifications. Hartge simply plugs in its revised engine computer, and output from both 2.0-liter I-4 turbo-diesels magically multiplies. Power delivered by the 18-spec 2.0-liter increases from 143 to 179 hp, while torque rises to 258 pound-feet at 2000 rpm. The chip itself is enough to allow a tuned rear-wheel-drive X1 sDrive18 to sprint from 0-62 mph in 8.1 seconds (1.5 seconds quicker than a stock example), and reach a top speed of 217 km/h.
Hartge's ECM for the 2.0-liter turbo-diesel I-4 found in the X1 sDrive20d and xDrive20d models adds an equal heaping of power to the diesel mill. Power increases by 32 horsepower to 171 ponies, while torque jumps 48 pound-feet to a solid 306 pound-feet at 2000 rpm. Two-wheel-drive models can blast from 0-62 mph in 6.9 seconds, but the all-wheel-drive form is no slouch, performing the same maneuver in 7.2 seconds.
Unlike Hartge's other products, the revamped X1 is largely devoid of wild cosmetic modifications. New coil springs drop the ride height by roughly one inch, which pairs nicely with the firm's 20-inch Classic 2 wheels. Inside, buyers can spring for a unique leather-wrapped three-spoke steering wheel, leather boots for the hand brake and shifter, and custom accessories bearing the Hartge logo.
According to the company, there are no limits as to how an X1 can be customized, but the degree "is only a question of price." We'd skip the emblazoned accouterments and spring for the 20d power chip, which runs European customers roughly $2400.
