The twin-turbocharged, all-aluminum, 3.0-liter inline-6 engine is characterized by lagless engine response to the accelerator pedal, fantastic sounds, and a free-revving spirit. The combination of twin low-mass turbochargers and BMW’s High Precision direct injection offers an output a naturally-aspirated engine would only be able to provide through more cylinders and larger displacement.
The turbocharger system developed for the engine of the new 1 Series M Coupe maintains a high output throughout the entire engine speed range. Maximum output of 335 hp (250 kW) is delivered at 5,900 rpm. Nominal peak torque is 332 lb-ft (450 Nm) from 1,500 rpm to 4,500 rpm. Redline is 7,000 rpm. The enhanced engine management system of the 1 Series M Coupe includes an electronically-controlled overboost function to briefly increase torque under full load by another 37 lb-ft (50 Nm). This temporary torque peak of 369 lb-ft gives the car a substantial increase in acceleration. The 1 Series M Coupe will complete the sprint from a standstill to 60 mph in just 4.7 seconds (0-100 kmh in 4.9 seconds). The standing quarter-mile mark comes up in 13.2 seconds. Top speed is limited electronically to 155 mph (250 kmh).
The exhaust system of the 1 Series M Coupe has been tuned by M specifically for this new model. Acoustic engineering gives the car a unique personality in all phases of operation. The M exhaust system is easily recognized by the usual Quad Exhaust on the other M-Powered cars.
The new 1 Series M Coupe also features the steering wheel-mounted M Drive button that made its first appearance in the 2005 M5. In the 1 Series M Coupe, the M Button activates a razor-sharp throttle response program for the sportiest driving. This means that the performance characteristics of the engine can be varied according to the driver’s wishes.
As an alternative to normal operating status, the driver can activate M Dynamic Mode (MDM) by means of pushing the MDM Button between the front air vents, raising the intervention thresholds of the DSC system. MDM enables slight amounts of dynamic oversteer under specific circumstances to enable optimum vehicle yaw for maximum performance. Demonstrations at the BMW Performance Center in Spartanburg, S.C. have proven MDM mode to enable the fastest-possible lapping performance while still providing the assurance and protection of Dynamic Stability Control. MDM also facilitates starting off in snow or loose surfaces by means of carefully controlled amounts of wheelspin. And most importantly the DSC may be fully disabled via a long-press of the MDM button (ABS remains active).
A close ratio 6-speed manual transmission is used for power transmission to the rear wheels in the BMW 1 Series M Coupe. It was specially designed to interact with high-torque engines and has been fitted for this purpose with a dry sump cooling system. An upgraded flywheel for high-torque applications is installed between the engine and transmission. The transmission is operated using a very short M gearshift lever. Final drive ratio is 3.15: 1.
German’s webzine Auto-News interviewed BMW M Division’s Dr. Kay Segler after the 24-hour race at the Nurburgring. Segler admitted that his motorsport division was developing a baby M powered car based on the 135i. The car will aim to admit younger buyers into the M club, given how out-of-reach the current entry-level M3 has become.
The name M1 is out of question due to respect for the original supercar (1978 to 1981) and wasnt confirmed to be the 135is either. The power unit is also unknown but it is assumed to pack more than the 322-340 bhp offered by the special Performance Power Kit. It goes on sale in relatively small numbers from the end of 2011.
Also Segler confirmed the new M5 will appear in late 2011. Its engine is based on the 4.4-litre bi-turbo V8 found in the X series M’s. The two pack a respectable 547 bhp, but the M5 is expected to top them considering the RS6 is 580 hp so expect a competitive power output.
Suppose this would be hard to dispute considering our photos of both M division cars.
One of the most untalked about and interesting races are the historic car races still happening around the world. Most recently at the Nürburgring 24h, the Classics undertook a classic 3h endurance race on the Nordschleife in Germany.
One car stood out from the impressive line-up and it is good to see that the Nelson Piquet 1980 car was on show at the 2010 ADAC Zurich 24h Classic race with a respectable best laptime on the Nordschleife and the GP circuit of 9:28.
This line of historic BMW M1s were produced by German automaker BMW from 1978 to 1981 and were the only mid-engined BMWs to be mass produced.
In the late 1970s, Italian manufacturer Lamborghini entered into a contract with BMW to build a production racing car in sufficient quantity for homologation into Group 4.
The result was the hand-built M1 coupe that was sold to the public from 1978 to 1981 under the Motorsport division of BMW.
The engine had six separate throttle butterflies, four valves per cylinder, and produced 277 PS (204 kW; 273 hp) in the street version, providing a top speed of 260 km/h (160 mph).
Turbocharged racing versions (this being one of them) were capable of producing around 850 hp (634 kW). The picture above is the same car Nelson Piquet drove with BMW M1 in 1980 at the Nürburgring, and the best reported time for the Nordschleife was an amazing 7:24. This was good compared to the current lap times of the Gumpert Apollo which is 7:11.
Only 456 production M1s were built, making it one of BMW’s rarest models. The spirit of the M1 lived on in the first ever M5, as both models shared the same, albeit slightly modified, engine. 356603356945351321351324351741351744
Today we spotted the child to the original BMW M1 not quite the legendary iconic masterpiece but the only fitting name for the 1 series based on the TI chassis.
A BMW 1 Series Coupe, tweaked by the company’s M division, Destined to slot beneath the M3 Coupe, the smaller 1 Series Coupe is said to feature a modified twin-turbocharged six-cylinder packing 349 horsepower. The aluminum engine will be mated to a standard six-speed dual-clutch gearbox with an electronically-controlled rear M differential. With a curb weight of just over 3,300 pounds and easily making more than 310-330 lb-ft of torque, Expect a 0-60 time of sub 5 seconds.
Also note the wheel arches rumour has it there is something very different under there!
