3 Differences between BMW M3 and M4 2015

BMW M, the high-performance division of the German company, presented the 5th. generating an auto legend that is now divided in two with the M3 four-door version and M4 for the coupe

The BMW M3 Coupé of the fourth generation, of which over 40,000 copies were made, gives way to the new model BMW M4 Coupe , which will continue the success story of its predecessor and, at the same time, with its type designation "M4" marks the beginning of the series that is based on the previous one.

For the first time simultaneously they premiered the coupe and four-door version, which the logic of naming types of models of the brand is the BMW M3 sedan.

The soul of the M

The engine is the heart of any model M ofBMW and the new six-cylinder turbo engine combines the advantages of a high-revving sucked with the qualities of turbo engine technology.

The consistent use of lightweight materials results in a weight reduction.

BMW replaced the V8 engine of 414 horsepower 4th. the generation of 3.0-liter six-cylinder in line with M TwinPower Turbo technology and high revolutions, completely new and specially developed for the BMW M3 sedan and the new BMW M4 Coupe, which has a maximum power of 425 horsepower between 5,500 and 7,300 revolutions per minute, which means that the maximum torque exceeds the predecessor by approximately 40%.

With this powertrain, both models can accelerate from 0-60 mph in just 3.9 seconds equipped with dual-clutch automatic transmission (4.1 seconds with the manual transmission is standard equipment).

Besides increasing the power consumption of gasoline was optimized by almost 25% compared to the previous generation, also because it was possible to reduce the weight of 176 pounds (80 kilos).

This reduction benefits the dynamic behavior and also increases the efficiency of both models.

Specifically, the BMW M4 Coupe weighs 3.300 pounds (1,497 kilos), which was achieved by the intelligent application of many measures the use of lightweight materials, including more widespread use of plastic reinforced with carbon fiber (the two models have ceiling carbon fiber) and also the use of aluminum in various components that are part of the chassis and body.

One of the priority goals for development work BMW M3 Sedan and BMW M4 Coupe was to obtain two models suitable for good times on race circuits.

Therefore, both have a cooling system configured for use in circuits capable of ensuring optimum temperature engine , turbo and gearbox.

And for the nature of sporting competition is not manifested only in technology but also in the fine tuning of the two cars, the engineers chose to work closely with professional drivers BMW Motorsport during the development phase.

The drivers Bruno Spengler and Timo Glock, both present in the DTM, participated with others in the many tests that were conducted in the northern variant of the classic Nürburgring in order to achieve optimum adjustment of the cars.

"The BMW M3 combines four generations their sporting genes with unlimited daily use, forming a concept that is capable of arousing strong emotions," said Friedrich Nitschke, President of the Board of BMW M GmbH. "The BMW M3 and the BMW M4 Coupe consequently remain faithful to this fundamental criterion.

BMW BMW M3 and M4 move the technology from motorsport to the road traffic.

Both models confirmed its qualities after thousands of fastest laps in the classic Nürburgring Nordschleife, the world's most demanding circuit.

A meticulous and passionate work of development got two high-performance models mark a new benchmark for its overall concept, accuracy and agility.

In the US market, the M4 Coupe will have a starting price of $ 65.125 and the M3 Sedan start at $ 62.925. Both prices include delivery charge and transfer.
