Q: What does GTI, GLI and so on mean?
A: L = Luxe (base model)
LS = Luxe Special, couple more do-dads
GT = Grand Tourisme, better equipped & usually a larger engine than
the "L" series
GL = Grand Luxe (geared for more luxury), basically == GT
GTI/GLI = Originally, the fuel injected version of a GT/GL which means it
produced a lot more power. With most cars FI, the GTI/GLI
designation means a more powerful engine than a GT/GL model,
sometimes also with a better suspension. Note that originally,
GLI != Jetta, as the case in the USA.
SL = Serie Limite' (limited series), like the Karmann series in US.
Really a variation on a GT.
GTX = Same as GTI but used in Europe and elsewhere.
G40/60 = GT version with VWs G-type supercharger. The number is the width
of the G-charger (lader in D) coil in millimeters. For those who
aren't aware, the G40 is used on some Polos, the G60 on Passats
and Corrados.
VR6 = Cars based on the new staggered 6 cylinder engine (in-line-V-6).
SLC = Sport Luxury Coupe, the VR6 equipped Corrado in the US.
Syncro = VWs version 4WD distributes its torque with a "visco-gear"
(It's a special silicone gel that stiffens if the relative
motion (shear) increases)
VWs 4WD is designed by Steyr-Puch, an Austrian Company and not
by Audi.
