2023 Porsche 911 Targa 4S

3.0L Twin-Turbo H6

Twin-Turbo Flat-6

A 3.0-liter twin-turbo horizontally-opposed six mounted out back, delivering the classic 911 blend of smooth low-end torque and a hard, metallic rush to its high redline.

Porsche's signature boxer-six layout dates to the original 1963 911; the modern twin-turbo version keeps the low center of gravity that makes the rear-engine 911 handle the way it does.

• The opposed-piston layout keeps the engine low and flat, dropping the car's center of gravity.
• Porsche has built the flat-six for the 911 continuously since 1963.
