2015 Audi RS 5 vs 2015 Lexus RC F - AutoGuide.com
Ostentatious Engines The components that give each of these fine automobiles their striking vigor, the mechanical heartbeats that provide rivers of thrust, are two alluring powerplants that are as similar on paper as they are different feeling... Starting alphabetically, the Audi RS 5 features an old friend, a 4. 2-liter V8. Two-by-fours of this displacement have been in the four-ring family for decades, it seems, and each year, they just keep getting better. Taking it to the max, time and time again is an exhilarating experience, as redline comes up quickly in lower gears and is accompanied by a mechanical noise akin to the music trumpeted by an F1 car’s exhaust pipes. But if you want more than the 316 lb-ft of twist provided by this engine, you should consider what the mechanical wizards at Lexus have conjured up. The RC F has a sizeable 800-cc displacement advantage, with a total piston-swept area of 5. 0-liters. Not surprisingly, that gives it a generous torque advantage as well, 73 additional lb-ft to be precise, every one of which you feel in the back-rise of your britches. Beyond that, the Lexus V8 also produces a few extra horsepower, with 467 on tap, a number it delivers without the frantic wail of the Audi. The RC F’s 5. 0-liter engine sings a different tune, one that’s more Woodward Avenue than Watkins Glen. Source: www.autoguide.com
