BMW je morao da oslabi V8 u novom M5 zbog EU propisa
Stroži ekološki propisi u Evropi već sada ostavljaju posledice na automobile visokih performansi. Jedan od najnovijih primera dolazi iz kuće BMW, gde je potvrđeno da je V8 motor u novom BMW M5 morao da izgubi deo snage kako bi zadovoljio zahteve Euro 7 regulative.
TL;DR
- New BMW M5's V8 engine power reduced from 585 to 544 horsepower to meet Euro 7 regulations.
- Modifications include altered engine software, improved exhaust gas treatment, and the introduction of the Miller combustion cycle.
- The Miller cycle enhances efficiency by reducing effective compression, leading to lower emissions at the cost of peak power.
- Overall system power for the M5 (727 hp) and XM (748 hp) remains unchanged due to optimization of the electric motor in the hybrid system.
- Euro 7 standards introduce broader testing conditions, including wider temperature ranges and consideration of particles from brake and tire wear.
- Despite reduced V8 power, real-world performance and acceleration are expected to be nearly identical to previous versions.
