Bmw S85 Bmw M5 E60 V10

The BMW S85B50 is a naturally aspirated V10 petrol engine which replaced the BMW S62 V8 engine in the M5 model and was produced from 2005-2010. It was both BMW's first and only production V10 engine, and the first petrol V10 engine to be available in a production wagon (estate). The BMW S85 engine, a naturally aspirated 5.0-liter V10, stands as one of BMW M's most ambitious engineering feats.

Developed for the E60 M5 and E63/E64 M6, the S85 was inspired by BMW's. The BMW S85 engine is a naturally aspirated 5.0-liter V10 powerplant, developed exclusively for the BMW E60 M5 and the E63/E64 M6. Debuting in 2005, the S85B50 V10 was a groundbreaking engine, embodying BMW's engineering prowess and commitment to performance.

The development of the BMW M5 E60 with its S85 engine began in the early 2000s. Back then, the gold standard in motor racing was 333 cc per cylinder, in series engines 500. If we take 100 hp per litre cubic capacity as the ideal in naturally aspirated engines and a goal of 500 hp, we need five litres of capacity distributed across ten cylinders.

At the time, V10 engines were seen as unusual. The BMW S85 engine represents the pinnacle of BMW's naturally-aspirated performance - a Formula 1-inspired V10 masterpiece that powers the E60 M5 and E63/E64 M6. At Partee Racing, we specialize in comprehensive S85 engine rebuilds that address the well.

Building or upgrading an S85 engine demands more than just parts - it requires precision, reliability, and proven engineering. KingTec Racing delivers all three with a comprehensive lineup of BMW S85 forged pistons, H-beam forged connecting rods, and forged crankshafts, designed to withstand the extreme stresses of both naturally aspirated and forced induction builds. The E60 M5 was one of only two BMWs to ever be produced with a V10 engine.

The ferocious 5.0L S85 engine generated a whopping 500bhp and 384lb.ft of torque. This made it the fastest four. BMW's S85 5.0L V10 engine powered the E60 M5 and E63 M6 from 2005 until 2010.
