The build and its results

The 2008 BMW 135d 1M Coupe Replica is a custom diesel tuning project with RS Diagnostics Stage 3. Its listed specification includes custom D5 pistons, a Stage 3 hybrid turbo, an upgraded fuel system with an R90 pump, and a six-speed automatic transmission with xHP Stage 3.

The owner’s listing states 480 HP and 1000 Nm. These are listing figures rather than an independent dyno verification on this page. The gallery preserves the original exterior, engine-bay and interior photos, while the cover is stylized.
