2004: FIFTH GENERATION
Labeled 8C35-04 (or Gen V), the fifth generation brought yet another technological leap for the 8C35 series. Direct fuel injection was now equipped
on all variants and this allowed running much higher compression ratios than before. Efficiency was improved greatly so yet again, even more power with
even less fuel burned was the result. Turbo engines switched to liquid-based intercoolers.
Gen V also brought along the first change to the actual engine block. Aluminium silicone was now used for both the block and the heads resulting in lower
weight. Surprisingly, the original cast iron crankshaft from 1973 was still being used on the entry-level normally aspirated 44V350 -engine.
Gen V notable features:
- All engine variants adopt Direct Fuel Injection system
- Aluminium Silicone construction for blocks and heads saving approx. 6% on engine weight
- Turbo engines adopt liquid-based intercoolers
- New engines have approx. 6% more power with approx. 15% better fuel economy
- Engine variants ranging from 350 to 525 hp; Xtreme series 630 hp

[size=85]The normally aspirated variants use 95 and 98 -octane fuel respectively, allowing the higher powered version to run more aggressive cams and engine mapping.[/size]

[size=85]Direct fuel injection allowed turbo engines to run much higher compression ratio thus improving low-speed response. Liquid intercooling enabled higher boost pressure to be used. The difference between the 450 and 525 hp variants is in compression ratio, valve timing and turbo sizing.[/size]

[size=85]The Gen V Xtreme version added yet another 100 horsepower compared to Gen IV. Compression ratio was up to 8.4 from earlier 7.7 courtesy of direct injection and individual throttle bodies.[/size]
