BMW Transitions to 2015 M3 In-Line Six Engine
While the BMW 3-Series lineup has undoubtedly become a symbol of luxury and performance with a loyal following from BMW fans, the laws of the land have prevailed.
The EPA’s laser-sharp focus on fuel-economy has “inspired” many car makers to abandon the larger, highly popular, naturally-aspirated V8 engine.
But the makers of the BMW M3 knew that for brand sustainability, switching out the mighty 4.0-liter V8 direct-injection gas unit for a twin turbo-charged, six-cylinder 3-liter, would give the (fifth generation) M3 more power while offering drivers the chance to save some money at the pump.
Bill Jacobs BMW agrees that the transformation of the 2015 BMW M3 and M4 will catapult the brand into the future, while satisfying the sensibilities of BMW purists by displaying the same sporty performance savvy the German auto maker has long been revered for.
One of the biggest benefits the changes made to the M3 is the ability to achieve 25 percent greater fuel efficiency and at the same time, increasing power from 414 to 425 horsepower.
Now, who can argue with more power? According to the numbers, that translates to about 40 percent more potency to be exact – including 406 pound-feet of torque, with the M3 reaching top speeds of 155 mph and rocketing off from 0 to 60 in 3.9 seconds.
So what’s behind the M3’s impressive thrust of power?
According to Dave Buchko, BMW’s product and technology communications manager, the engine powering the 2015 M3/M4 cars are nothing like the twin-turbocharged engines most people are used to. The power plant for the two new M cars is constructed with a weight-reducing aluminum block and cylinder-head and a light weight magnesium oil pan. The combination of a dry sump oiling system and a trac-spec engine cooling system and Direct injection maintain the engine temperature. A new forged crankshaft and carbon fiber drive-shaft were added to reduce drivetrain weight and rotating mass. Which improve throttle response for faster acceleration.
Aluminum front fenders, hood, and doors in addition to the use of carbon fiber in the roof’s exterior, trunk lid, and drive shaft, not only create a lighter body, but shaves about 176 pounds from the vehicle’s overall mass compared to the fourth generation M3.
Lastly, a more aerodynamic design offers less drag for improved fuel economy. A point that Bill Jacobs BMW believes will cater to even the most particular BMW enthusiasts.
