A topic going around the web this morning is a report from Motor Trend on BMW’s M Sport division and their plants to move towards four and six cylinder turbo engines.

If you’re a loyal reader of our blog, then you might recall that back in November, we reported similar news regarding BMW’s decision to steer away from the large naturally-aspirated engines and replace them across the M line with turbo engines.

MotorTrend talks about the new M cars coming out in 2014 with the first turbo engines, but that’s a bit of a misconception. The first M models to be powered only by turbo engines, in this case the twin-turbo ones, are the X5 M and X6 M which will be unveiled next month.

The so rumored BMW 135i Supersports, an M1-like model, is  being confirmed once again, as a car that will be placed below the M3.

We are working on it, but only as business cases are concerned, as solutions are concerned. Because you’re looking at a car in the neighborhood of 1300 kilos (about 2860 pounds, roughly equal to a VW GTI). And you would need at least 300 horsepower. I would love to have a car like that in our range. It would also be a good thing to get the interest of younger customers again.

The long time rumored turbo four-cylinder engines are definitely coming.

How far along is a turbo M four cylinder? “At the very beginning. This would mean a twin turbo four cylinder in a car that is below the M3. This would only be a story for the next 1 Series, so you’d be looking at 2014 or so.”

Rumors are that BMW has not decided yet is if the new engines will be inline-six or the more popular V6 engines, but of course, take this with a grain of salt. According to Ludwig Willisch, BMW’s M division CEO, the new M3 will have a wider body, similar to the platform of the new 3 Series.

Of course, the use of a twin-turbo engine will add more weight to a car that has been criticized of growing in size with each generation, but Herr Willisch doesn’t seem to be too worried.

Engines don’t need to be more powerful for the next car. As long as you have lighter weight, you have better performance

But in the end, BMW seems to be seriously considering the V6 option since it gives them the possibility to move the engines further downwards providing a better balance and weight distribution.

Metrics and intensive testing will decide the faith of the new M engines, and either an inline-six or V6 option, will provide the customers with the desired outcome: a high-performance, fun to drive BMW.

Even though we covered in the past many of the things published by MotorTrend, I encourage to head over and read the full article, it’s a nice refresher and comprehensive article.
