Audi Presenting 94 MPG, 700 HP Sport Quattro PHEV At IAA
September 6th, 2013 by Nicholas Brown
Audi has announced that it will present the Sport Quattro PHEV at the International Auto Show (IAA) in Frankfurt. This vehicle has three modes:
In EV mode, the vehicle operates on electricity only. This mode can be used both in and outside of the city. The Audi Sport Quattro PHEV can travel 31 miles (50 km) in this mode.
This involves the use of the electric motor and combustion engine, although not necessarily simultaneously. It decides whether or not to utilize the electric motor alone or simultaneously with the combustion engine, depending on environmental factors, in order to maximize efficiency for the chosen route.
In this mode, the vehicle adjusts itself to maximize performance when selected. As there is often a tradeoff between performance and efficiency, this mode is reserved for when the driver really wants speed. Think of this as having your cake and eating it too, you can enjoy both high fuel efficiency and speed.
According to Green Car Congress, this vehicle generates an impressive 700 HP, 590 pound-feet (700 N·m) of torque, which enables it to accelerate from 0-62 MPH (0-100 km/h) in 3.7 seconds. It also achieves 94 MPG! Which car can achieve that combination?
Apart from that, the Audi Sport Quattro PHEV achieves this with an idea that came to mind a couple of years ago (I wasn’t sure if it would work, but i’m glad to see it did): it is called the Cylinder On Demand (COD) system. COD allows the twin-turbo, 4-litre, 8-cylinder engine to shut off 4 of the cylinders when the engine is at part load (a formal way of saying, “when they aren’t needed”). This efficiency is also partly attributable to the use of a start-stop system which makes the engine idle less often.
The vehicle is constructed partly of aluminum body panels and carbon-fiber-reinforced polymers (plastics) to reduce weight without compromising durability.
This TFSI engine is assisted by a 110 kW (147 HP) electric motor between it and the transmission, which generates 295 pound-feet (400 N·m) of torque. This disc-shaped electric motor is powered by a liquid-cooled lithium-ion battery in the back, which has a capacity of 14.1 kWh.
