Check out this review of the S85 V10-Powered E46 M3


A very smart owner decided to replace the naturally aspirated 3.2-liter inline six with their E46 M3 and replace it with a 5.0-liter S85 series naturally aspirated V10 E60-gen BMW M5. The engine-replaced M3 began hitting the interwebs a few weeks ago and for good reason. Not only is it much faster than any stock E46 M3, but it sounds absolutely delicious. However, most of the videos we saw only showed its appearance and sound. In this new video from AutoTopNL, we can actually see a review of what it’s like to drive.

Obviously, replacing the six-cylinder engine with a ten-cylinder engine made the E46 M3 much faster and more exciting, but there was also another addition that dramatically improved the driving experience: a DCT. Rather than using the old six-speed sequential manual transmission (SMG) of the E60 M5 and even the E46 M3, this owner replaced the transmission with the E92 BMW M3’s seven-speed dual clutch transmission (DCT). This did two things to improve the unit of this M3; it made the shifts much faster and made them much smoother.

The combination of the screaming V10, which in its series form produced 500 horsepower and exceeded 8,000 rpm, and a quick-change DCT makes this BMW M3 E46 a real sight to drive. While the standard S85 engine sounds amazing, this car has a custom exhaust with the M Performance muffler of an E92 M3. It looks amazing in this video, especially when walking through a small tunnel. It’s also amazing to see how much difference the DCT makes, as the shifters look just as good as a modern sports car, while the old SMG has always been the biggest complaint of older M cars.

This build is one of the most beautiful, ambitious and interesting E46 M3 builds we have ever seen. The only thing we don’t like is that it’s in Germany and we can’t drive it.
