Possibly a silly question... car engines?
Most of you may chuckle at this question from a novice like myself, but I'll go ahead and ask anyway...
Why are care derived engines not used in GA?
I think the DA40TDI first used a 1.7 Isuzu engine, commonly found in Vauxhalls, and this got me thinking. How about a 3L BMW turbo diesel, 184/203 bhp depending on variant, and excellent fuel economy. I'm pretty confident it could handle a constant 3000rpm, as these things can sit on motorways for hours at 4-5000rpm.
Would anyone care to expand on this?
Many Thanks,
Simon.
