I think this is a loaded question, since it really doesn't give any context.
Volkswagen Group has been making gasoline fueled engines since before WW2. There are air cooled, water cooled, inline, boxer, V, VR, 3, 4, 5, 6, 8, 10 cylinders, OHV, SOHC, DOHC, gear, belt, chain driven cams, naturally aspirated, turbocharged, supercharged, port injected, CIS injected, direct injected, carburetted, magnesium case, aluminum case, cast iron, .... the combination is basically as varied or possibly more so than any other manufacturer.
And the vehicles in which they were bolted have been just as varied. Rear engine, front engine, mid engine, RWD, FWD, AWD, transverse mounted, longitudinal.
Heck, they even built a few hybrids!
The last of the REALLY good gasoline fueled engines that was sold in this country left the dealer showroom last year, and it was only found in the Jetta S. Simple, sturdy, tough, reliable, tried and true. I'd place that engine 9and its precursors dating back to 1998) over ANY other VAG gasoline fueled engine sold here in the last 25+ years, and I'd place it on par with the ALH TDI in general ease of service and durability. Heck, it shares much of the same basic design.
