Based on the Q60 Red Sport 400, the Alpha concept previews a range of performance upgrades that will soon be available from Infiniti dealers.

AMS Performance has created special intercoolers, intakes with dry media filters, high flow exhaust downpipes, a catback exhaust system, revised ECU calibration and a high capacity heat exchanger.

The upgrades are claimed to bring a 19 percent increase in horsepower and 29 percent higher torque, elevating the 3.0-liter turbocharged engine to 476 ponies and more than 450 pound-feet of twist.

Infiniti has not announced when the performance upgrades will be available for Q60 buyers.
