Audi hybrid vehicles
Template:Use dmy dates Script error: No such module "Unsubst".
Audi hybrid vehicles are hybrid electric vehicles created by the German carmaker, Audi. Some vehicles listed were concept vehicles, which utilised an internal combustion engine and an electric motor, and were used for research and development (R&D) for potential future use of the technology into possible series production. Audi launched its first hybrid concept car in 1989 called the Audi Duo, and was the first European company to sell a hybrid in 1997, though only in very small numbers.
Audi Duo
The original Audi Duo (styled duo) was created in 1989 and was first shown at the Frankfurt Motor Show,[1] and was based on the Audi C3 100 Avant. It was a petrol engine/electric hybrid concept vehicle. It was powered Script error: No such module "convert". five-cylinder petrol engine that drove the front wheels, and a part-time electric motor that could be activated when the vehicle was stationary, developing Script error: No such module "convert". and drove the rear wheels. It used nickel-cadmium batteries.[2]
Audi 100 Duo II
Audi 100 Duo second generation concept car was introduced in 1991. It featured Audi's "trademark" quattro permanent four-wheel drive system. Powered by a four-cylinder 2.0 L engine with Script error: No such module "convert".), with a Script error: No such module "convert". electric motor for the rear wheels when required. In electric mode the front axle was disconnected, and in this mode the Duo could reach a claimed top speed of Script error: No such module "convert". and the sodium-sulfur battery sufficient for 80 km (49.71 miles).[2]
Audi A4 Duo III
The Audi Duo III was introduced in 1997, based on the Audi A4 Avant, and was the only Duo to ever make it into series production.[3] The Duo III used the Script error: No such module "convert". Turbocharged Direct Injection (TDI) diesel engine producing Script error: No such module "convert"., which was coupled with a Script error: No such module "convert". water-cooled electric motor. Both engine and motor powered the front wheels only, unlike the two previous concept Duos. There was a switch inside the cabin for changing between the electric motor and the engine. The batteries would be recharged during highway or country driving, or by plugging the car into an AC power outlet. The electric motor could also recover energy during deceleration and in electric mode the Duo had a range of approximately 50 kilometers (31.07 miles) and a top speed of Script error: No such module "convert"..[2]
The hybrid was unable to achieve fuel efficiency much greater than the standard 1.9 TDI, due to the extra weight the lead gelatin batteries added. There was little demand for this hybrid due to its high price, and thus only about 100 Duos were produced. The Duo was the first European hybrid ever put into production and Audi would not sell another hybrid until early 2011.[3]
Audi Q7 hybrid 4.2 FSI quattro
Script error: No such module "Labelled list hatnote". Audi unveiled the Audi Q7 hybrid 4.2 FSI quattro, which uses their Fuel Stratified Injection (FSI) 4.2-litre V8 engine, at the 2005 Frankfurt Motor Show. Audi had planned to have the Q7 hybrid as a part of their 2008 model range, but never did.
Audi metroproject quattro
Script error: No such module "Labelled list hatnote". The metroproject quattro is a supermini/sub-compact, and was shown to the public at the 2007 Tokyo Motor Show.[4] Under the bonnet/hood is a 1.4-litre TSI petrol engine, producing Script error: No such module "convert"..[4] This will distribute its torque of Script error: No such module "convert". to the front wheels via an 'S tronic' Direct-Shift Gearbox.[4] However, in the back of the car, beneath a perspex peephole, is a Script error: No such module "convert". electric motor which drives the rear axle, and can generate an additional Script error: No such module "convert". of torque, designed to create a zero emissions driving[4] experience in residential or city areas, and increase torque while the 1.4 TSI engine is accelerating.
A lithium-ion battery pack supports a range of up to Script error: No such module "convert"..[4] In electric mode, the car has a top speed of more than Script error: No such module "convert"..[4] When both the engine and electric motors are working in unison, the car is transformed into a genuine quattro, with a combined torque output of Script error: No such module "convert". being shared between all four wheels.[4] Stop-start technology will be utilised,[4] as will regenerative braking. As a result, Audi claim a 15% improvement in fuel efficiency when compared to exclusive use of the internal combustion engine.[4]
The A1 started production in 2010 but without a hybrid. There are also no plans to add such later; instead Audi plan an all-electric version.
Audi Q5 hybrid
The Q5 is Audi's first large-scale production hybrid model on sale, first announced at the end of 2010, and sales started during 2011. Powered by a 2.0-litre TFSI turbocharged and direct injected petrol engine, producing 208 bhp, and a Script error: No such module "convert". electric motor providing a combined total output for the hybrid system is 241 bhp and 354 lb ft. Drive goes to all four wheels, and the gearbox is an eight-speed automatic, but without a torque converter as the electric motor also acts as a starter motor and as a generator. The 1.3 kWh lithium-ion battery sits under the boot floor.[5]

Batteries
Audi is planning an alliance with the Japanese electronic company Sanyo to develop a pilot hybrid project for the Volkswagen Group. The alliance could result in Sanyo batteries and other electronic components being used in future models of the Volkswagen Group.[9]
