France's answer to the Sierra/Sapphire Cosworth. It's 173hp was pretty pokey in it's day, the E30 BMW 325i made do with 168hp, and its FWD chassis was supposedly pretty decent (i don't ever recall seeing a Quadra badged one in the wild, so i imagine they were pretty rare). Meh.
(The red car in the 2nd photo is a 21 TXi, not a Turbo, BTW)
