More powerful and efficient than ever:
the new A3 Sportback TFSI e
Dublin, October 15, 2024 – With a higher battery capacity, DC charging at fast-charging stations, and an electric range of up to 141 kilometers*, the Audi A3 Sportback TFSI e is undergoing a comprehensive upgrade. Its intelligent drive management ensures outstanding efficiency, high recuperation performance, and locally emission-free driving over long distances in everyday life. Orders can be placed from Mid-October.
After Audi presented extensive upgrades for the A3 and S3, including the new A3 allstreet model, in the spring, the A3 Sportback TFSI e now follows with the plug-in hybrid more powerful and more efficient than before.
New turbo petrol engine and optimized electric motor as powerful duo
The primary components of the driving system are the new, turbocharged petrol engine and the higher power density electric motor. With its many high-tech features, the 1.5 TFSI evo2 takes the place of the previous 1.4 TFSI. The Miller cycle, the turbocharger with variable turbine shape, and the early intake valve closures work together to maximise combustion chamber cooling and guarantee a greater compression ratio. Compared to the 1.4 TFSI, the ratio was 10:1; it is currently 11.5:1. This combustion approach lowers emissions and fuel consumption while enabling the new unit to function with high efficiency. Up to 350 bar of pressure is used during injection.
By comparison, the 1.4 TFSI reached a maximum of 200 bar. Plasma-coated cylinder liners reduce internal friction in the new engine. Pistons with cast-in cooling channels optimize combustion.
The electric drive is provided by a permanently excited synchronous motor, which now delivers 85 kW and 330 Nm of torque. As with its predecessor, it is integrated into the housing of the six-speed S tronic, which is now equipped with a more robust gearbox bearing to cope with the higher system output.
It transfers the torque from the two engines to the front axle. The dual-clutch transmission has an electric oil pump that ensures the change of gears and oil supply even when the TFSI is temporarily deactivated.
Battery capacity and energy content of the HV modules doubled
The gross capacity of the high-voltage battery is now 25.7 kWh and has, therefore, almost doubled with nearly identical dimensions to the predecessor model. The net capacity is 19.7 kWh. Its 96 prismatic cells, which are divided into four modules, store significantly more energy than before: thanks to optimized cell chemistry and a better package, the charge quantity of the modules is now 73 instead of 37 ampere hours. The developers have thus increased the electric range to up to 143 kilometers in the WLTP cycle. A dedicated cooling circuit ensures the battery temperature is maintained in the optimum range.
More power for the sporty A3 Sportback 45 TFSI e
Audi offers the A3 Sportback TFSI e in two performance levels: 40 TFSI e2 and 45 TFSI e1. In the more powerful model, the 1.5 TFSI evo2 delivers 130 kW (177 PS), which is 20 kW (27 PS) more than before. The maximum torque is 250 Nm, which is available between 1,500 and 4,000 revolutions per minute. In combination with the electric motor, the A3 Sportback 45 TFSI e1 delivers a total of 200 kW (272 PS) system output and 400 Nm system torque. This enables it to achieve strong driving performance: The acceleration from 0 to 100 km/h takes 6.3 seconds. The model reaches a maximum top speed of 237 km/h.
In the smaller version, the combustion engine has an output of 110 kW (150 PS) and also develops 250 Nm of torque. The new 1.5 TFSI evo2 and the electric motor provide 150 kW (204 PS) of system power. When they work together with maximum boost, the system torque is 350 Nm. The A3 Sportback 40 TFSI e2 accelerates from 0 to 100 km/h in 7.4 seconds and on to a top speed of 225 km/h. The all-electric top speed for both models is 140 km/h.
Intelligent drive management for maximum efficiency
High efficiency is the goal of the drive management system of the small plug-in hybrid. The car can function like a fully electric model if the driver chooses to prioritise the electric drive using the EV button on the switch panel or by selecting it in the MMI. The combustion engine and electric motor intelligently divide the workload in "Auto Hybrid" mode, the main operating mode. At low speeds, the vehicle is entirely electric, but at higher speeds, the TFSI engine takes precedence and frequently both drive simultaneously. The A3 Sportback TFSI e can coast, recover (both in braking and propulsion), or boost in tandem with the electric motor and TFSI, depending on the circumstances. In addition, the hybrid management system keeps the battery charge level constant to save enough electrical energy for later use, for example, in a low-emission zone.
Recuperation via the steering wheel paddles
When you take your foot off the accelerator pedal, the A3 Sportback TFSI e coasts with the engines switched off, or the electric motor recuperates in overrun mode. This depends on the driving situation when automatic coasting recuperation is selected. As with all-electric models, the steering wheel paddles are used to control the degree of coasting recuperation. The selected gear is set in the background.
When braking, the electric motor takes over the deceleration alone up to around 0.3 G and thus covers the vast majority of all braking processes in everyday driving. The hydraulic wheel brakes only come into play when you step harder on the brake pedal.
More power when boosting
The A3 Sportback TFSI e reveals its sporty potential in shift program S of the dual-clutch transmission. In the “Dynamic” drive select mode or when the kick down is activated, the drive system delivers the full system power and releases the boost power in the acceleration phases. In the A3 Sportback 40 TFSI e2, this is 40 kW and is available for up to 15 seconds or up to 40 seconds under optimal conditions. In the A3 Sportback 45 TFSI e1, 70 kW is available for up to 18 seconds because the electric motor has to deliver more power to exploit the full system potential. In EV mode, the combustion-engine vehicle also switches on during kickdown, and the boost power is called up.
DC fast charging function with up to 50 kW
For the first time, Audi is offering DC charging at fast-charging stations for a plug-in hybrid model. The A3 Sportback TFSI e uses DC charging with up to 50 kW* and thus allows comfortable traveling with electric drive. This means a battery discharged to 10 percent can be recharged to 80 percent* in less than half an hour.
In addition, it is possible to charge at AC charging points such as a wallbox or municipal charging stations with three-phase charging at up to 11 kW. The charging process takes 2.5 hours. The necessary Mode 3 cable is included as standard. Audi's own charging service, Audi charging, provides access to around 630,000 charging points in 29 European countries on request, including Audi's own charging hubs in Berlin, Munich, Frankfurt, Nuremberg, Zurich and Salzburg (further locations to follow). A single card can be used to charge conveniently there and at numerous other providers.
Specifically tuned chassis
Compared to the conventionally powered A3, the axle load distribution in the plug-in hybrid is slightly more rear-heavy, with 55 percent on the front axle and 45 percent on the rear axle. This is due to the lithium-ion battery, which is located under the vehicle floor in the area of the rear seat bench. The suspension and dampers have, therefore, been specifically tuned. The combination of slightly increased spring rates and a somewhat sportier damping behavior ensures high ride quality and dynamics in equal measure. The electromechanical steering works sensitively and provides support depending on the driving speed. It offers a precise steering feel at high speeds; when parking the A3 Sportback TFSI e feels very easy to handle. Progressive steering with a variable ratio depending on the steering angle is available as an option for an even more agile driving experience.
New functions and sporty equipment for the 45 TFSI e
The plug-in hybrid models benefit from the innovations introduced on the A3 at the beginning of the year: sportier styling, new design elements, and digital offerings. Extended standard equipment increases comfort, selectable daytime running light signatures, and the flexible addition of vehicle functions ensure a high degree of individualization.
Both plug-in hybrid models are equipped with 17-inch alloy wheels, the Audi drive select dynamic handling system and stationary air conditioning as standard. Special displays provide information about the drive: the graphically revised power meter in the Audi virtual cockpit shows the power currently being called up, the drive mode, the battery charge status, and the range. The MMI display also visualizes the energy flows.
In keeping with its higher performance, the A3 Sportback 45 TFSI e comes with the S line exterior as standard, which includes an S-specific radiator grille and an S roof edge spoiler. The black plus styling package accentuates the Audi Singleframe, the trim strips on the side windows, and the bumpers. The exterior mirror housings also shine in black; the Audi rings are in anthracite gray.
The striking exterior is completed by red brake calipers and darkened rear windows as standard. In the interior, black sports seats, aluminum-look applications, and door sills with aluminum inlays reflect the sporty character of the A3 Sportback 45 TFSI e.
Available at prices from 44,200 euros
Prices for the A3 Sportback 40 TFSI e start at 44,200 euros, while the more powerful and sportier 45 TFSI costs from 47,700 euros. Orders for both models can be placed from October. The A3 allstreet as a plug-in hybrid version will also follow in the fall.
*The value for the charging process calculated according to DIN 70080 is 40 kW. A maximum charging performance of up to 50 kW is possible. At DC charging stations this can vary depending on a number of different factors including the ambient and battery temperature, the use of other country-specific connectors, the use of the preconditioning function (e.g. remote-controlled air conditioning of the vehicle), the capacity available at the charging station, the state of charge and battery ageing. Charging capacity is reduced as the state of charge increases. Charging losses are considered.
