The new 5.7-liter HEMI® V8 has plenty of new features that push it to the front of the pack and deliver better freeway merging acceleration than Ford or Chevy[1]. It also sports the best combination of horsepower and fuel economy in its class[2].
- Multi-Displacement System (MDS) seamlessly deactivates half of the engine's cylinders in fuel saver mode when less power is needed.
- New variable cam timing (VVT) delivers increased torque and efficiency.
- Stronger hemispherical cylinder heads produce more power, while a new short runner valve active intake manifold increases fuel efficiency[3].
Available 4.7-liter SOHC V8 two-valve engine is proven powerful and durable.
- Single overhead camshafts provide excellent performance.
- Valve train and combustion chamber allow low-speed torque, smooth idle and reduced engine noise.
The 3.7-liter V6 engine produces competitive V8 power and torque.
- Single overhead camshafts deliver outstanding performance while maintaining improved fuel economy.
