ZIL-4102

Now, in some alternate dimension, there probably is a world where executives enjoy the ZIL-4102 in place of a Mercedes-Benz S Class or beefed-up Eagle Premier. (It looks like one, eh?) 

Anyhow, four were built between 1987 and 1991, and it was a front-drive sedan powered by one of three V8 engines, including a diesel—that remained on the shelf and was reportedly never installed in a prototype. The good one to have, according to some sources, is presumably the "tuned" option on the 6.0-litre V8—though with all that weight up front, I can't imagine it was a very athletic car.

Some body panels were made from fibreglass to save weight, and it was a true unibody design—the Wikipedia page for the car seems to think this was the first Russian car so constructed, but I doubt it…right? The only performance numbers I can dig up suggest a zero-to-100 km/h (62 mph) time of about 10 seconds.

Apparently made at the direction of then-President Mikhail Gorbachev because the state limos were looking outdated, the 4102 was designed only after engineers dissected a Rolls-Royce Silver Spirit…or so the story goes.
