BMW’s 1M, which has only recently started to arrive at U.S. showrooms, will be a one-year car and will end production in December 2011 at the latest. BMW plans for the 335hp version of its pint-sized 1 Series to be available in showrooms for several months only.
This 2011 model, the latest offering from its vaunted M division, is priced at $46,135. Offering a limited edition and making it available for short runs isn’t unusual for BMW M or even its rival Mercedes-Benz’s AMG division.
But because of the strong demand and high profits associated with producing models such as the BMW M3 or Mercedes CLS63 AMG, the carmakers chose to make these models a regular part of the lineup. In an interview with TheDetroitBureau.com, Matt Russell, the U.S. M brand manager, said that the 1M will have a limited run for many reasons.
BMW implies that it may be working on a future update but it may take some time before the model dubbed 1M goes back to the U.S. since the more conventional 1-Series will be getting a major update.
It usually takes several years before BMW comes out with a high-performance M edition of any of its conventional products. The 1M name may be a source of confusion for some fans as BMW’s other products built by the brand-within-a-brand are typically given a designation such as M3 or M5.
Behind the revving, throbbing heart of every BMW is its engine. It forms the backbone, framework and drive for the brand and the inline-6 continues this chapter with outstanding performance and endless thrust.
The 1-series M Coupe is familiar to all and deservedly content with its place in history. It has a classic engine format which the second and third generations of M3 were famous for. By combining high output, razor-sharp response and sonorous sounds, the BMW 1-series M Couple with the inline-6 engine concept is realised in its most up-to-date form.
Drawing an instant response from the its twin-turbocharged, all-aluminium, 3 liter inline-6 engine, the M Coupe sounds fantastic and still maintains its free-revving nature. Combining twin low-mass turbochargers and BMW's High Precision direct injection provides an output you would expect to feel with more cylinders and larger displacement from a naturally-aspirated engine.
The turbocharger system which has been developed for the new 1-Series M Coupe's engine maintains the high output you would expect from a BMW delivering an impressive 5,900 rpm from 335hp (250kW). With a nominal peak torque of 332 lb-ft (450 Nm) from 1,500 to 4,500 rpm, the BMW model redlines at an enhanced 7,000 rpm. The 1-Series M Coupe's engine management system now includes an electronically-controlled over-boost function to briefly increase its torque under full load by another 37 lb-ft (50 Nm). Giving the car a substantial improvement in acceleration with a torque of 369 lb-ft, if only temporarily.
With a top speed, electronically limited, to 155 mph (250 kmh), the BMW 1-Series M Coupe is now able to go from 0-60mph in just 4.7 seconds (0-100 kmh in 4.9 seconds), and a standing quarter-mile mark comes in at 13.2 seconds.
Distinct sound to go with the power boost
The exhaust system of the BMW 1-Series M Coupe has been specifically tuned for the new model. The car retains its one-of-a-kind personality due to the acoustic engineering in all stages of operation and the exhaust system remains recognizable by the existence of the four signature exhaust pipes.
M Drive Button
Now featuring a steering wheel-mounted M Drive button which was first seen in the 2006 M5, the M button activates an extremely sharp throttle response program for even the sportiest driver. This allows the new 1-Series engines performance features to conform to the driver's preferences.
6-speed Manual Transmission
The BMW 1-Series M Coupe has a close ratio 6-speed manual transmission that is intended for power transmission to the rear wheels. It is built particularly to work together with high-torque engines and due to this purpose, it was built with a dry sump cooling system. In addition, a redesigned flywheel for high-torque applications was placed between the engine and the transmission. Running this transmission is a very short M gearshift lever. This model has a final drive ratio of 3.15:1.
