Merkur XR4Ti and Ford Sierra RS Cosworth: Ford's Most Perfect Mistake — Revelations w/ Jason Cammisa

The Merkur XR4Ti was an award-winning, turbocharged home-run for Ford in the 1980s — until it landed in U.S. dealerships with a thud. How could this have happened? The XR4Ti was the German-built turbocharged, 4-cylinder version of the Ford Sierra XR4i — a futuristically styled, rear-wheel drive sporty coupe. With more power and more refinement than its European-market sibling, the Merkur was the better car. Conceived by the legendary Bob Lutz, the brand-name "Merkur" was chosen so that the XR4Ti (and later Scorpio) could be sold outside of the U.S. Ford, Lincoln, and Mercury dealerships — to compete against the E30-chassis BMW 3-series, the Audi 4000 and Coupe, and the W201 Mercedes 190E. It easily outperformed them all, using a revised version of the turbocharged 2.3-liter "Pinto" 4-cylinder also seen in the Mustang SVO, Thunderbird Turbo Coupe, and Mercury Cougar XR7. Mated to a 5-speed manual, the XR4Ti out-accelerated the contemporary Ferrari 308 GTB Quattrovalvole and won over car-magazine editors. But not customers. And the reason? Ford Corporate didn't listen to Bob Lutz (always a mistake) and gave Merkur to its existing Lincoln-Mercury dealers, who were unequipped and not incentivized to sell the small, expensive European premium coupe. Customers hated the dealers, and, well, the XR4Ti didn't sell. Meanwhile, in Europe, things got even hotter when the lineup grew to include the Ford Sierra RS Cosworth. With a Cosworth-built aluminum DOHC 16-valve head on a 2.0-liter version of that same Pinto block, it made 204 hp (metric; 201 SAE hp) and left everything for dead — including and especially in various Touring Car Championships. The final homologation Evolution model (the RS500) is, by at least one measure, the most successful race car of all time. And yet we never go the RS Cosworth in the U.S., partly because of how poorly the XR4Ti sold. This is the history of the short-lived Merkur brand — and how a poor dealership experience can ruin even a great car.
