BMW E46 3-Series M3(S54B32)와 330(M54B30) 엔진 비교 시 같은 NA 인라인 식스 실린더이고 VANOS를 모두 사용하는데도 출력 차이가 큼 (M54: ~230HP vs S54: ~340HP). 배기량 차이(3.0L vs 3.2L)로는 설명할 수 없는 큰 성능 차이의 원인이 무엇인지 궁금함.
M3(S54) 엔진의 주요 장점들: 1) 엔진 블록 재질 - 330은 알루미늄-실리콘 합금이지만 M3는 주철 블록 사용으로 고하중에서 변형 저항성 우수. 2) 압축비 - M3는 11.5:1, 330은 10.2:1로 더 높음. 3) 캠축 리프터 - M3는 솔리드 리프터로 고회전 대응 (8,000rpm vs 330의 유압식 7,500rpm). 4) 캠샤프트 프로필 - M3는 더 적극적인 프로필로 밸브 오버랩 증대. 5) 스로틀 바디 - M3는 실린더당 독립 스로틀 바디(ITB) 채용으로 각 기통에 최적화된 흡입 공기 공급, 330은 플레넘 챔버 방식.

원문 보기 ↗Reviews of the M350 are starting to hit the websites of the big magazines - all pretty positive. Looking like if you're sticking with combustion it's another really good 3 Series.
Kudos to the original owner.

Transverse engine, front wheel drive, rubber cone suspension? We want our inline, rear drive, leaf sprung that we're used to.It's just gopping. It's taken the ugly bits from the current one (particularly the F&R lights) and made them even worse. Shame, as everything up to and including the F30 looked great. Even the Bangle ones were decent-looking.If you want a good-looking Bimmer the last one is the G30 5 Se

I've found myself in the fortunate circumstances recently to be able to justify an extra driveway slot filler. Filling this final driveway slot would be a hindrance, in that it would make it harder to park, harder to load a 3 year old into the back of whichever car we wanted to use, make washing any of the cars very difficult without relocating something to the street temporarily... but it would fit a much needed requirement.I've never owned a car with more than four cylinders, or with more than 2.0 litres of capacity.I've been fantasising about what vehicle could help me fix this for years, a

I’m on the brink. We live in the lakes now and this would tick the do-it-all machine. Tbf, so would a 2023/4 FFRR PHEV which are £60k less and now come with a 2yr LR used warranty ! But the Octa is more fun and a much more serious road SUV for a laugh. I’m also having the - get a Nomad plus a FFRR for the same money thought….

Growing up in a small Scottish village in the 1980s, anything remotely exotic was a rare sight. Supercars lived in magazines, not on our roads.Then a new lad joined the school. His family moved into a very flash bespoke house on the edge of the village and, more importantly, his dad was a proper petrolhead. For the first time in my life I saw a Porsche in the flesh. I was about eight years old, and there it was: a Guards Red Porsche 944 sitting on the driveway.To an eight-year-old boy, it may as well have been a Ferrari F40.I stood staring at the thing in complete awe and made myself a promise
