Performance and Powertrain: Heart of the Beast

When it comes to performance, the Audi S4 and Infiniti Q50 Red Sport bring serious firepower. The heart of the S4 is a potent 3.0-liter turbocharged V6 engine, churning out around 349 horsepower and 369 lb-ft of torque. This engine is mated to an eight-speed Tiptronic automatic transmission and, of course, Audi's legendary Quattro all-wheel-drive system. The Quattro system provides exceptional grip and handling, making the S4 a blast to drive in various conditions, from dry pavement to snowy roads. The S4 can sprint from 0 to 60 mph in about 4.4 seconds, making it one of the quickest cars in its class.

On the other side of the ring, the Infiniti Q50 Red Sport boasts a 3.0-liter twin-turbo V6 engine, producing a more considerable 400 horsepower and 350 lb-ft of torque. The Q50 Red Sport comes with a seven-speed automatic transmission and is available in either rear-wheel drive or all-wheel drive configurations.

The Q50's engine feels incredibly responsive, with plenty of power on tap for quick acceleration and confident passing maneuvers. The Red Sport trim also features upgraded brakes and sport-tuned suspension, enhancing its performance capabilities. So, if you're looking for raw power and a more aggressive driving experience, the Infiniti might be your cup of tea.
