The 2024 Porsche 911 Twin Turbo S AWD

The 2024 Porsche 911 Turbo S brings a significant leap in performance with its new biturbo engine.
The engine now delivers 478 kW (650 PS), which is 51 kW (70 PS) more than its predecessor. The torque has also increased by 50 Nm to 800 Nm.
The development of this new engine focused on improving performance and meeting emissions standards. It features a gasoline particulate filter (GPF) to achieve this. The goals of the development also included improvements in responsiveness, power, torque characteristic, emissions, and revving ability.

To achieve these improvements, the engine incorporates new, larger VTG turbochargers, an electrically controlled wastegate flaps system, a redesigned charge air cooling system, and the use of piezo injectors.
The intake system of the engine has been modified to include forced induction. This involves a change in the routing of process air and charge air cooling.
Part of the process air now flows through the Turbo air intakes in the rear side sections, and two other airflows through the rear lid grille have also been incorporated.
This design change results in four intakes with a larger overall cross-section and lower wind resistance, ultimately improving engine efficiency.

The newly introduced symmetrical turbochargers with variable turbine geometry (VTG) have larger dimensions and rotate in opposite directions. The turbine wheels have been increased in diameter, and the wastegate flaps are electrically controlled with stepper motors, providing advantages in terms of catalytic converter activation, boost pressure control, and precision.
The compressed air then flows through the repositioned charge air coolers, which are now 14 percent larger and located directly over the engine in a central position under the rear wing. This new position enhances cooling efficiency and improves air inflow and outflow of the cooling air.

To transmit the high torque reliably and with minimum losses, a new eight-speed dual-clutch transmission (PDK) has been introduced. This PDK has been adapted to the power delivery of the engine and offers improvements in comfort, performance, and efficiency. The gear ratios have been optimized, and the final-drive ratio has been lengthened to reduce engine speeds in higher gears and improve fuel consumption.
The 911 Turbo S also comes with the standard Sport Chrono package, which includes various driving modes, dynamic engine mounts, and the Porsche Track Precision app. The car features an innovative Wet mode that detects wet road surfaces and adjusts the car's systems accordingly to ensure optimal driving stability.

The improved Porsche Traction Management (PTM) all-wheel-drive system offers even more traction, safety, and driving pleasure. The front-axle transmission can transmit significantly more torque to the front wheels, and a new, lighter driveshaft distributes power to the front axle.

The 911 Turbo S is equipped with a new lithium-ion lightweight starter battery, which offers higher voltage stability, lower internal resistance, and improved auto start/stop function. The battery also allows for longer operation of energy-intensive systems with the combustion engine switched off, resulting in more fuel-saving stop phases.

Additionally, Porsche offers an optional sports exhaust system for the 911 Turbo S. It features electric, continually adjustable exhaust flaps and creates a distinctive sound typical of Turbo models. The sports exhaust system is visually distinguished by two oval tailpipes in black or silver.

Overall, the new biturbo engine in the 911 Turbo S delivers impressive performance and incorporates various technological advancements to improve power, efficiency, and driving dynamics.
