Five-Cylinder Frenzy - 2018 Audi RS3 & TT-RS
The 2018 Audi RS3 and TT-RS warble into the U.S. marketIf you're reading this, I'll bet dollars to donuts you know all about the ur Quattro, the original Quattro Coupe sold in the United States from 1983 until 1986. Supposedly, 664 cars were imported—legally at least; a few more made it in somehow. In 1983, the techno-wonder debuted with a price tag of $35-large, a decent amount more than the Porsche 911 at the time. Sporting big box-flares, a turbocharged inline five-cylinder engine, and most importantly all-wheel drive (unheard of in performance cars in the 1980s), the Quattro was the true car-geek's performance choice. The turbo five-cylinder continued on for several years in different platforms, but it never had the same impact of the ur Quattro. There is a reason we are still talking about it 30 years later.
When Audi brought the turbocharged inline-five back in 2010, it lived under the hood of the first TT-RS; enthusiasts rejoiced. Partly for the return of the iconic warble produced by the odd-numbered engine, but also at the thought that it might end up under the hood of something like the S5 or even the Quattro Concept, which Audi began teasing not long after the announcement of the engine. I was one of those enthusiasts. I thought the TT-RS was a fantastic idea, and although I didn't get to drive one until the car made it to the States in 2012, I still loved dreaming about the possibility of a five-cylinder-powered S5.
The truth is, it never would have lived up to enthusiasts' expectations. The supercharged 3.0L V-6 that eventually replaced the 4.2L V-8 in the S5 was basically the perfect choice for that car at the time. The current S5 uses a turbocharged V-6, which is also a better choice for the cars with the longitudinal drivetrain layouts. Very quickly: In Audis with the engine and transmission sitting longitudinally, the entire engine sits forward of the front axle. Other manufacturers make all-wheel-drive cars with the differential either sitting under or alongside the engine, so the engine's mass is more centrally located. Since a V-6 is only three cylinders long instead of five, it is the better choice. The V configuration also gives a lower center of gravity than an inline engine, so while the idea of a longitudinally mounted five-cylinder stokes the fire of nostalgia, physics comes along and extinguishes our flame—again.
