Even though it has been out of production for over a year now, the 1 Series M Coupe remains one of the coolest models ever offered by BMW->ke178. To sweeten the pot even more, BMW built just 2,700 units, making it one of the most appreciated BMW models.

German tuner, Sportec, obviously loves the 1 Series->ke313 M, as it is serving up a pair of upgrades for the compact Bimmer. In its natural state, the 1M->ke2536 Coupe is plenty powerful, as it delivers a total of 335 horsepower at 5,900 rpm and 332 pound-feet of torque from 1,500 rpm to 4,500 rpm. This is enough to launch the compact coupe to 60 mph in just 4.6 seconds.

In Level 1, Sportec reprogrammed the ECU to push the output to a total of 385 horsepower and 442 pound-feet of torque. By our estimation, Level 1 should drop the naught to 60 mph time to about 4.3 seconds.

Level 2 is more complex, as and includes a larger oil cooler, a downpipe with 100-cell metal catalytic converter and a sports air filter. As a result, the TwinPower 3.0-liter in-line-6 engine delivers a total of 420 horsepower and 479 pound-feet of torque, which we estimate to drop the 0-to-60 time to just over 4 seconds.

BMW 1 Series M Coupe by Sportec in Detail

The Level 1 upgrade costs €1,250 ($1,630 at the current exchange rates) and Level 2 runs €4,200 ($5,400).

Along with the engine upgrades, the tuner decided to replace the standard six-speed transmission with a new double-clutch gearbox from the M3. Unfortunately, Sportec does not offer a price for the transmission conversion.

The exhaust system was also replaced with a new one with control valves and titanium tailpipes. The exhaust system is priced at €3,422 ($4,460).

Next, the tuner focused on reducing the car's total weight by installing a new roof membrane, a rear cover and new carbon-fiber seats.

The car now sits on a set of 19-inch ultra-light forged wheels priced at €5,470 ($7,130) and combined with an adjustable suspension system priced at €3,395 ($4,400).
