Franken-Bimmers – What is your perfect BMW Combination Build?


After seeing the Cars and Bids E38 BMW 7 Series with an E39 BMW M5 heart transplant, my mind started racing and filling with other fantastic BMW combinations. While an E38 7-series with an E39 M5 engine is as perfect as it gets, it’s always fun to play around with different combinations. So I thought it would be a fun exercise to create more exciting Franken-Bimmers.

I’ll create my perfect Franken-Bimmer first and your readers can follow it, leaving your perfect BMW builds in the comments below. There really aren’t any rules other than that all parts of the build must be road legal and made by BMW. Not necessarily a BMW model, but they have to be made by BMW. For example, a McLaren F1 engine counts like a BMW engine, just not from a BMW vehicle. It also has to be at least semi-realistic, so something like an F1-powered BMW 2002 won’t actually work as that engine won’t fit. So let’s start.

My perfect Franken-Bimmer would have to start with my favorite BMW chassis – the E46 M3. The balance, the handling and the driving feel of the chassis are not only unsurpassed in any modern BMW, but also one of the best-looking BMWs ever. So that would be my starting point. As good as the 3.2-liter straight-six of the E46 M3 is, I would take it out and use the naturally aspirated 4.0-liter V8 from the E92 M3.

The idea is to recreate the E46 BMW M3 GTR for the road as this GTR racing car used a P60B40 4.0 liter naturally aspirated V8 for racing. It was barely legal in the racing series it competed in, so it was never legal on the street, so it’s excused from this exercise. However, the E92’s 4.0-liter, free-breathing V8 is still a sensational engine and probably the best ever built into a road-going M3. Also, I would know that it would somehow fit (at least close enough for this exercise) since the M3 GTR’s engine was the same displacement and it did fit, with modification of course.

Pair that engine with a six-speed manual transmission and one of BMW’s clever electronically controlled rear axle differentials and my Franken-E46 M3 would be essentially perfect. I would also like it in Dakar Yellow with a black interior and E46 M3 CSL wheels.

So this is my Franken-Bimmer. Now it is your turn to create your own in your head and share it with the group.
