The DeLorean DMC-12 has a bespoke 'backbone' chassis designed by Lotus.
He had Pontiac engineers drop a big V8 into a Tempest. It wasn't a particularly impressive feat of engineering.
At least you've gotten
something right. It isn't a chunk of stainless steel. The chassis itself is steel coated with an epoxy for rigidity, followed up with Lotus designed underbody panels made of an epoxy resin, covered with brushed 304 stainless steel. The car weighs about 2,800 pounds with all the fluids.
As much as most of you have written it off because of the meagre 130hp output of the 2.8L PRV V6, it's actually an excellent handler. Its chassis and suspension is similar to an Esprit of the day. It isn't quite as good as the Esprit in the corners (chalk that up to the big V6 and rear mounting of said engine; it was actually supposed to be mid-mounted but was pushed back to accomodate a golf bag behind the seats), but it can certainly give it a run.
The engine was a modified version of the PRV V6, so it isn't actually a Peugeot, Renault or Volvo version specifically. It's an amalgam. The exterior (belts, hoses, housings, etc.) closely resembles the Renault design, whilst the innards are mostly Volvo-spec. It didn't make as much power as, say, the Volvo version, because of a
lot of emissions-cleaning equipment grafted on. In fact, ripping out the catalytic converter and a few other bits and pieces will garner up to 15 horsepower alone. European versions of the engine had no emissions equipment and ran on leaded gasoline, and subsequently made 145hp.
Its biggest problem was the engine and transmissions. The PRV started only when it wanted to, and the Renault transmissions had a habit of ****ting themselves after mildly hard driving. The three-speed automatics were rumoured to fry their electronics if the car was improperly jump-started.
Beyond that, the detractors among you are unfortunately missing out on what was a very good touring car. Certainly one of the best of the '80s. Regardless of your preconceived notions, the DeLorean is still an impressive performer. The Lotus engineers didn't **** about. (It's too bad the Renault engineers did.)
