Jeep JL Wrangler 3.6L vs 2.0T Horsepower / Torque Dyno Curve Comparison


Written by:

Numbers don’t always tell all when it comes to engines. Maximum horsepower and torque figures are easy to compare engines with but what’s even more telling about an engine’s performance and how it delivers its power is the engine’s horsepower and torque curve profiles.

In this useful comparison dyno chart put together by a JLWF member, you can see how the JL Wrangler’s 3.6L V6 Pentastar compares to the new 2.0L Turbo 4 Cylinder engine in how they deliver HP/TQ.

The 3.6L V6 Pentastar is factory rated at 285 hp / 260 lb-ft while the 2.0L Turbo 4 Cylinder is rated at 270 hp / 295 lb-ft. On paper, the 35 lb-ft torque difference seems substantial.  The HP/TQ comparison chart shows that the difference may feel even more substantial in real world driving. Because the 2.0L features a turbo (versus the naturally aspirated 3.6L), it develops its torque faster and hits peak torque earlier, which generally translates to a feeling of bigger thrust. Whether this is a preferable driving experience is subjective of course, as there are some owners who may prefer more linear acceleration.
