The 1M is widely regarded as one of the best M cars BMW ever rolled out. However, whoever created this particular 1M must not have been satisfied with its speed, as they decided to fit it with the V10 engine from an E60 M5.

The car is listed for sale by Grand Sportscars for €59,900 ($58,043), and it has around 19,000 km (11,806 miles) on the odometer. That’s quite a hefty sum, even accounting for the money spent on modifications, but apparently, the special 1M made an appearance on a TV show, which could be a factor in its pricing.

Aesthetic-wise, the 1M sports metallic green paint, which is complemented by black 20-inch Wiesmann wheels and orange brake calipers. On the topic of those brake calipers, the front ones come from an F10 M5, while the rears come from an E90 M3. Other visual upgrades come in the form of a carbon fiber roof, rear decklid, and mirror caps, though the latter two items are paint-matched to the rest of the body.

As mentioned before, under the hood of this 1M is the S85 V10 from the E60 M5, which is attached to that same car’s SMG automated manual gearbox. That powerplant also received some upgrades in the form of an ESS supercharger, water/methanol injection, and a custom Friedrich exhaust.

Power figures on the listing suggest that those upgrades don’t boost the V10’s output from stock, but upon further research of the car’s alleged TV fame, the upgraded V10 actually pumps out a whopping 641 hp (650 PS / 478 kW). That being said, even the stock 500 hp (507 PS / 373 kW) is considerably more than the 335 hp (340 PS / 250 kW) produced by the 1M’s original inline-six.
