Self Study Program 990123 – Audi Q5 hybrid quattro

VAG SSP 990123. The Q5 hybrid quattro is the first Audi hybrid model with twin drive systems. Its 2.0L TFSI engine develops 211 hp (155 kW), operating in tandem with a water-cooled electric motor developing 54 hp (40 kW). The electric motor is powered by a compact lithium-ion battery.

AUDI AG can look back at over 20 years of experience with hybrid technology. The first generation of the Audi duo, a hybrid concept car based on the Audi 100 Avant, made its European debut in 1989. A five-cylinder gasoline engine drove the front wheels and a part-time electric motor developing 12 hp (9 kW) drove the rear wheels. Rechargeable nickel-cadmium batteries provided the energy source.

Another duo variant based on the Audi 100 Avant quattro followed two years later.

In 1997, AUDI AG became the first European manufacturer to build a limited edition hybrid production vehicle. It was based on the Audi A4 Avant.

Drive for this A4 was provided by a 1.9 liter TDI engine developing 90 hp (66 kW), and a atercooled electric motor developing 29 hp (21 kW). This front-wheel drive vehicle used an electric motor powered by a lead-gel battery that could be recharged by plugging into an electrical outlet.

The A4 Avant duo electric motor could also recover energy during deceleration. In electric mode, the duo attained a top speed of 50 mph (80 km/h) and a maximum speed of 105 mph (170 km/h) with TDI power.

Further development in hybrid technology was showcased in the Audi R18 e-tron quattro prototype race cars at the 2012 24 Hours of Le Mans. Audi dominated the competition, taking first and second place, becoming the first manufacturer to win the legendary race with hybrid technology. The winning cars featured a TDI turbo diesel engine powering the rear wheels, and an electric motor powering the front axle for greater acceleration coming out of corners.

In addition to hybrids, Audi is also developing a new family of electrically powered vehicles (e-tron) capable of driving long distances. The Audi A1 e-tron, designed for congested city driving conditions, always operates electrically. No additional gasoline or TDI engine is used to extend driving range.
