The S55 debuted in and was the first mass-produced M Division engine with a turbocharger. However, bmw s55 engine, devotees had nothing to complain about because the S55 was a fantastic engine and a good basis for the forced-induction engines that would likely bmw s55 engine the M vehicles in the near future. Here's all you need to know about the BMW S The N55 debuted in on the F07 5 Series Gran Turismo as the German manufacturer's first mass-produced engine with a twin-scroll turbocharger.

As the BMW S55 engine gets older, we are learning more and more about long-term reliability, common problems, and important preventative maintenance. It's no secret that aging high-performance BMWs need more maintenance than your average vehicle. Many older BMWs, especially M cars, have acquired quite a poor reputation for dependability - particularly when the miles start to stack up. But we don't think it's always deserved. Sure, there are a few examples such as the rod bearings found in the BMW E60 M5's S68 V10 that would wear prematurely, fail, and cause catastrophic engine failure.

The S55 was introduced in in the F80 M3 and F82 M4 models, based on the single-turbo N55 but with a raft of changes on board. Since its launch, it has found its way into the F87 M2 Competition in a slightly de-tuned form, as well as in slightly higher states of tune in the Competition and CS versions of the M3 and M4, while the hottest version was fitted in the M4 GTS. After almost 30 years of high-revving, naturally aspirated engines spread across four generations of M3, with fours, sixes and eights found beneath their bonnets, the move to turbocharged power for the F8x generation of M3 and M4 was never going to be a popular one, but it was inevitable and very much a sign of the times. Spare a thought for both BMW and the S55 — the company and its new engine had an almost impossible act to follow, that being the mighty S65 V8. The S55 that emerged may not have seemed all that impressive at first glance, seeing as it was based on the much-used N55 that had featured in numerous BMWs. At 84mm and The S55 makes just 11hp more than the S65, though it is produced much lower down the rev range between rpm, making it more accessible. The move to forced induction did mean that the S55 was rather better endowed than the S65 in the torque department. Where the naturally aspirated V8 had to make do with lb ft, the same as the N55, the twin-turbo S55 develops a meaty lb ft from rpm, giving it some monster mid-range punch. The engine also employs direct injection, Valvetronic, and double-VANOS and uses a closed-deck crankcase design, which increases rigidity and allows cylinder pressure to be increased for maximum power. Instead of cylinder liners, the cylinder bores of the S55 feature a twin wire arc-sprayed coating, which helps reduce engine weight.

The BMW N55 is a turbocharged straight-six petrol gasoline engine that began production in The N55 was BMW 's first straight-six engine to use a twin-scroll turbocharger. It also won three straight Ward's 10 Best Engines awards in — The main differences between the N55 and its N54 predecessor are the use of a single turbocharger, the addition of Valvetronic and the type of fuel injectors. Whilst the N54 used a twin-turbo arrangement, the newer N55 uses only a single twin scroll turbocharger. The piezo injectors were more expensive and BMW decided they were not worthwhile outside of Europe, because the potential benefits of lean-burn operation could not be fully realised. The exhaust manifold design, called Cylinder-bank Comprehensive Manifold CCM by BMW, aims to reduce the pressure fluctuations to reduce throttle lag and exhaust back-pressure.

Its demise came at the hands of the S55 — the first mass-produced M Division engine to feature a turbocharger. The introduction of the S55 was a considerable step away from the kind of engines that typically powered a BMW M car. However, enthusiasts were left with little reason to complain as the S55 was a phenomenal engine and a solid foundation for the forced-induction engines that are likely to power the M cars in the immediate future. Although based on the N55, the S55 shares little in common. Yes, figures like the 84 mm bore, The core improvement that this brings compared to an open-deck design is added rigidity; this, in turn, allows for higher cylinder pressures and consequently more power output. The cylinder bores also featured a twin-wire arc-sprayed coating — an atomized spray of metal that is a complex but lighter solution than conventional cylinder liners. The pistons themselves are made of a Grafal-coated aluminum alloy that reduces friction.

Sure, there are a few examples such as the rod bearings found in the BMW E60 M5's S68 V10 that would wear prematurely, fail, and cause catastrophic engine failure. The tabs on the camshaft hubs would break off, end up in the timing chain, and cause catastrophic engine failure. It's a similar story for the V8-powered E9X BMW M3 which commonly suffered from rod bearing failure, throttle body actuator failure, oil consumption, and more. Lots of these reliability issues aren't unique to BMWs but, for certain models, the failure rate was unnaturally high.

Why did BMW cancel their new supercar? Failure will be sudden and catastrophic. Add to cart Sold out. Toggle limited content width. But we don't think it's always deserved. BMW has also equipped the S55 with an electric water cooling pump that helps regulate the temperature of individual components like the turbocharger and transmission. Introduced as the heart of the G80 M3 and G82 M4, and extending its prowess The solution is to perform regular intake valve cleaning using walnut blasting or chemical methods. M GmbH engineers also created a cooling system that contains a primary radiator as well as an extra radiator for the low- and high-temperature circuits. Just like with most BMWs, quality parts are a must. You should know that the S58 is the better-performing engine right off the bat. BMW engine manufactured from — Yes, figures like the 84 mm bore, At the turn of the millennium, it revealed the M54 and the performance-oriented S54 shortly after and cemented itself as one of the best in the business when it came to the six-pot layout.

The BMW N55 is a turbocharged straight-six petrol gasoline engine that began production in The N55 was BMW 's first straight-six engine to use a twin-scroll turbocharger.

Higher-spec iterations of this engine producing more power were available with the Competition packages of the cars above. As previously stated, one of the most noticeable distinctions between the S55 and the N55 on which it is based is the adoption of a closed-deck crankcase design. Videos See all. Replacing this failed gasket require dropping the sub-frame which is a very labour-intensive process. This is a very common issue for the S BMW has also fitted the S55 with an electronic water cooling pump, which aids in the temperature regulation of specific components such as the turbocharger and transmission. Like with every engine, the S55 also showed some common problems that owners of the M2, M3, and M4 reported. Add to cart Sold out.
