- For the Manual Transmission Lover: The 3.6L Pentastar V6 is your only option if you desire the engaging experience of rowing your own gears.
Engine Performance and Driving Experience
The driving experience varies noticeably between the two engines:
- 3.6L V6: Offers a linear power delivery, a pleasant engine note, and a well-matched pairing with either the precise 6-speed manual or the smooth 8-speed automatic. It feels robust and predictable.
- 2.0L Turbo I4: Provides a more immediate surge of power off the line and strong mid-range acceleration. The turbo whistle is subtle, and the eTorque system makes the automatic start/stop almost imperceptible, contributing to a refined urban driving experience.
Maintenance and Longevity
Both engines are designed for durability and longevity, provided they receive proper maintenance. Adhere to the manufacturer’s recommended service intervals for oil changes, filter replacements, and fluid checks. The 3.6L V6 has a long track record of reliability.
