What year and model Chrysler is this?

As already stated, the Omni/Horizon was built to compete with the VW Rabbit, it was actually a European Simca prior to becoming the Omnirizons here. Yes it had a larger(1.7 vs 1.6) VW 4cyl. when introduced, and the 1.6 Peugot 4cyl., which got sold in a lot of fleet-car deals.
The GLH 4Dr was road tested buy one of the big rags(forget which one), and it turned the fastest time through the slalom cones of any production car ever tested by them to that date, no Lambo, no Ferrari, no Vette, no Porsche, ever went that quick through that test.
Hot Rod mag I believe, pitted the Classic GT350 'Stang vs a GLH-S on a road course, & the Omni stomped it. They are not "drag racing" machines, but they are judged by that here all the time, lol.... go to some road courses even with a decent straight, and there are Miatas lapping contemporary 'Vettes..
