n Audi continuously updated product line, for its layout for electric cars, the second half light alone Q5, A8, A6 and A7 Sportback Release TFSI e plug-in hybrid vehicle. In 2019 draws to a close, the further introduction Q7 TFSI e quattro, combined with 3.0 l turbocharged V6 engine and a permanent magnet synchronous motor, brings both performance and fuel consumption performance.
Audi Q7 TFSI e quattro V6 TFSI 3.0 liters equipped with turbo engine, the maximum output horsepower and a maximum torque of 340 450N.m, a separate engine has been able to meet the emission standards Euro 6d-TEMP. PSM with permanent magnet synchronous motor, 126 horsepower output and 350N.m, the composition of the plug-in hybrid system.
Depending on the power, divided Q7 60 TFSI e quattro and Q7 55 TFSI e quattro two models. Q7 60 TFSI e quattro maximum horsepower to 456, peak torque of 700N.m. 8-speed Tiptronic transmission, in boost mode 0 ~ 100km / h acceleration 5.7 seconds, speed up to 240km / h, the electric motor alone with the maximum speed of 135km / h; Q7 55 TFSI e quattro Some weaker force, maximum horsepower 381, the maximum torque 600N.m. However 0 ~ 100km / h slower acceleration only 0.2 seconds to 5.9 seconds, the maximum speed with the maximum speed and pure electric these two data and the same Q7 60 TFSI e quattro.
Q7 TFSI e quattro mounted to 168 units of 14 modules of the water-cooled lithium-ion battery, a position mounted in the luggage compartment under the floor, the capacitance for17.3kWh. The cooling system will generally be formed at a low temperature independent circulation circuit, but if necessary can be supplied with air-conditioning and the cooling loop for cooling the motor power of the motor and connected to the second low-temperature circuit, in order to obtain a better cooling effect. Two identical models in pure electric mode driving range, is 43 km.
In addition to the electric-EV mode, the Hybrid hybrid mode, there are two operating functions, namely Auto and Hold. In Auto function, operation prediction logic will open with navigation and action, the system will predict road travel situation, the decision to use different power strategies. For example, in the city will use the time to stop and go more motor power, places the main engine, motor, supplemented by the high-speed sections; the Hold function is enabled, the system will be subject to the current charge, it will not consume as much as possible.
