simply say "Engine Transverse" is bad.
Every thing has its cons and pros. I believe "Transverse" may cause some performance loss,
but may have some gain in other areas.
I checked this stuff on wikipedia, here is
what I found.
"A transverse engine is an engine in which the crankshaft is oriented side-to-side relative to the length of the vehicle. This is also sometimes called an east-west engine. Most modern front wheel drive vehicles use this engine orientation (with the exception of some Audis), while most rear wheel drive vehicles use a front-to-back longitudinal arrangement."
"This has also allowed for improved safety in a frontal impact, due to more front to back engine compartment space being created. The result is a larger front crumple zone."
