Panamera S/4S Engine

Engine

General Information

An enhanced generation of V8 engines is used for the new Panamera models: A 4.8-liter V8 naturally aspirated engine for the Panamera S and a 4.8-liter V8 bi-turbo engine for the Panamera Turbo. The enhanced and optimized engines used in the Panamera are based on the Cayenne engines. This made it possible to achieve the ambitious targets for fuel consumption and CO2 emissions despite the enhanced performance.

Development Objectives

Reduction in weight using lightweight design measures, such as:
- Timing case and valve covers made of magnesium (5.5 lbs./2.5 kg lighter)
- Fully aluminum, lightweight camshaft controllers (3.7 lbs./1.7 kg lighter)
- Aluminum bolts for magnesium parts and for connecting engine and transmission (2.2 lbs./1.0 kg lighter)
- Lighter crankshaft and connecting rods designed specifically for naturally aspirated engines (5 lbs./2.3 kg lighter)
- Magnesium oil guide housing specifically for the Panamera S


Lower fuel consumption and lower emissions by installing various systems, such as:
- Start/stop systems
- Heat management using a map-controlled thermostat (with integrated flow suppression)
- Direct fuel injection (DFI)
- VarioCam Plus
- Demand-controlled oil pump

High performance due to:
- Larger throttle valve, 82 mm (Panamera S)
- Pressure sensor for measuring mass air flow
- Sport button as standard
- Intake system with variable intake manifold

Compact design with:
- Front-axle differential flanged to the engine
- Engine installed at a lower position
- Very flat oil guide housing made of magnesium (S) or aluminum (Turbo, 4S)
- Manifold and turbocharger produced as a single unit without an intermediate flange (Turbo only)
- Integrated dry-sump lubrication

V8 Naturally Aspirated Engine







Engine type M48.20 for 2WD
Engine type M48.40 for 4WD

The 4.8-liter V8 naturally aspirated engine in the Panamera S and 4S has the following main features:
- Newly designed, lighter crankshaft and lighter connecting rods
- Oil guide housing made of magnesium (Panamera S) or aluminum (Panamera 4S)
- Intake camshafts optimized for power output and torque curves
- Intake system with variable intake manifold
- Larger throttle valve for greater power
