Ford Built A Cayman GT4…in 1985 — The Carmudgeon Show w/ Jason Cammisa & Derek Tam-Scott — Ep. 188
The Ford Sierra RS Cosworth is best described as... Porsche-great. This week we’re doing a deep dive into Ford’s funky sedan of the 1980s: the Sierra, together with its American identical cousin, the Merkur XR4Ti.
In the early 1980s, Ford of Europe (and chairman Bob Lutz) was on a mission to get a piece of the export pie that was dominated by Mercedes, BMW, and Audi. The car they conjured up to do so, the Sierra, was a massive success in Europe.
When it eventually made it to the U.S., badged as a Merkur XR4Ti, Lutz's plan to sell the cars to yuppies via independent niche dealers was foiled, and the car was placed on Lincoln-Mercury dealer lots alongside big American barges and clueless salesmen, only to die a slow death.
Meanwhile, on the other side of the pond, the extra-spicy Ford Sierra RS Cosworth was born. In fact, the car was so sought-after (i.e. stolen) by British hooligans that insurance companies refused to cover them. And it was so fast it was repeatedly banned from racing, eventually effectively spelling the end for Group A racing.
Ford of Europe (headed up by Bob Lutz) was seeing the likes of BMW and Audi making a killing with their U.S. exports and Ford wanted in. The plan was to try something different, and rather than a Ford-branded import program where Sierras would be sold alongside LTDs, Cougars and other giant American sedans, Bob wanted to do a Ford of Europe export scheme where their new car could be sold alongside other European curios like Saabs and Volvos at independent dealers under a new brand name. They settled on Merkur (the German word for mercury – pronounced “maercoor”), but they also needed a new model name as Sierra was trademarked by Oldsmobile (think: Cutlass Ciera.) Ford used the “XR” prefix to denote a variety of upgraded model trims followed by a number which corresponded to the vehicle size – which is where XR4 comes from. Add abbreviations for “turbo” and “injection” and you’re off to the races!
Both the Merkur and Sierra RS Cosworth were powered by versions of Ford’s Pinto 4-cylinder motor. The Merkur engine could also be found in the USDM Mercury Cougar XR7, Thunderbird Turbo Coupe, and Mustang SVO. Across the pond however, the Sierra engine went to Cosworth to get an aluminum head with an extra cam. The results were clear: the XR4Ti’s motor needed 13 lbs of boost to pump out 175 hp, while the Cosworth version only needed 8 psi to make 200 hp.
But the Cosworth got a whole host of additional modifications beyond the engine, and the resulting package was so exceptional it wound up getting banned from racing repeatedly, until eventually the regs shut down the entire series. The chassis is so exceptional that Jason proclaims it the best sedan chassis he’s ever experienced – on the same level as a Porsche Cayman GT4. Transcendent. A 9.9/10. Where "Beatrice," his extensively modified E30, only managed a mid-8 (for the same reasons that caused Sreten at M539 Restoration to drive his into a tree). The likes of the Lotus Carlton didn’t even garner a 5 from either Carmudgeon. Honorable mentions go to the Maserati Quattroporte, C126 560SEC, and a handful of M products. We’ll even dive into every generation of M5 – E28 through G90.
Lastly, we’ll learn about 80s and 90s Lexus dealership brutalism, that “light” means window, our friend Mike’s transient collection of eclectic cars has graced the show at least 3 times (thanks, Mike!), superbly compliant AWD cars like the Delta Integrale and Subaru WRX are good but rarely fun, and Bob Lutz had to fight tooth and nail to get a Chevrolet dealership in NorCal to sell him a Corvair Monza.
