The current BMW M3 Sedan has been on the road for for some time now, and has proven to be a great car. However, as is always the case in the automotive industry, there is day a approaching when it’s out with the old and in with the new. The incoming 2015 M3 Sedan has already been introduced, and is lighter and more powerful than it’s predecessor, and offers some impressive new tech.
Powered by a 3.0L in-line 6-cylinder, twin-turbocharged engine that delivers 425 hp (317 kW) and 406 lb-ft of torque, makes the new M3 Sedan more powerful than the V8 of the outgoing model. According to BMW, the 2015 M3 Sedan is able to accelerate from 0 to 60 in just 3.9 seconds when matched with the optional M Double Clutch Transmission (M-DCT). Equipped with the 6-speed manual transmission acceleration from 0 to 60 is said to be a still impressive 4.1 seconds. Top speed is electronically limited to 250 km/h, and 280 km/h with the optional M Driver’s Package. Even more impressive is that the enhanced performance comes with a 25% improvement in fuel efficiency over the outgoing model.
Although the EPA gas mileage estimates for the 2015 BMW M3 Sedan are not yet available, the promise of 25% greater efficiency is good news. The previous M3 was a bit of a thirsty beast, returning only 14 mpg in the city and 20 mpg on the highway. Based on BMW’s estimated fuel consumption, the new M3 Sedan should get around 18 mpg city driving and 25 mpg on the highway.
Some of the fuel savings can be attributed to a slightly reduced curb weight. According to BMW, on comparably equipped M3 models there is a savings of about 176 pounds over the previous generation. The lighter CFRP (carbon fiber reinforced plastic) roof is available for the first time on the M3 sedan in the 2015 model. The weight savings with the change of material for the roof alone is 11 pounds. Weight was also saved with the use of aluminum in the manufacture of the hood and front fenders, and more CFRP in the drive shaft, strut brace, and numerous other parts.
The new M3 benefits from the full range of infotainment found in the standard 3-Series cars. There will also be an array of other features, including a BMW M Laptimer app for smartphones that is connected to the car’s on-board computer. The app can record the car’s speed, longitudinal and lateral acceleration, engine revs, steering angle, accelerator position, fuel consumption, and more. Which gear is engaged and is also displayed for M-DCT equipped models, and all of the data is stored so it can be analysed later. An optional heads-up display includes some M-specific features, such as a gear indicator display, rev counter, and the “Optimum Shift Indicator”.
Production of the new 2015 BMW M3 Sedan will be at the BMW plant in Regensburg beginning early in the summer of 2014.2
