"I sampled both powertrains in my drive in, over, around and through the wilds of Tucson, Ariz., and found the V-6 to be adequately smooth and powerful. But the new turbocharged 2.0-liter four-cylinder is even better. Mated only to the automatic transmission, it makes 270 hp and 295 pounds-feet of torque but feels amazingly torquey, punchy and quick around town. I drove a four-door model loaded up with a hardtop, three full-size humans and a lot of camera gear, and the turbo engine felt responsive and zippy, with the eight-speed auto shifting seamlessly and smoothly through the gears. Only on some low-speed corners did I find it in a gear lower than I wanted, but the transmission's quick-shifting nature and utter lack of turbo lag poured on speed with remarkable ease. As much as the addition of the 3.6-liter Pentastar engine transformed the Wrangler into a usable daily-driver in 2012, that's how much better the new 2.0-liter is for 2018.
"Ride and handling have also received a massive shot in the arm thanks to a revised suspension, wider axles, improved tires and a new electrohydraulic steering system (with an electric motor-driven pump). The Wrangler still drives like a light truck -- you won't confuse this for a car-based Toyota RAV4 or Jeep's own Cherokee -- but no longer does it feel ponderous or sloppy around turns. The Sport and Sahara models were well-controlled, provided acceptable steering feedback and even had a decently comfortable ride over rough pavement. It feels like a modern mid-size pickup truck, such as a Chevrolet Colorado or Toyota Tacoma, in that it's no longer a penalty box, but it's still not quite the smooth and well-damped environment of a Jeep Grand Cherokee. Only so much can be done to hide the fact that there are still two solid live axles front and rear, and in stiff crosswinds you'll still get blown all over the highway (you are driving something with the aerodynamic profile of a small single-family home, after all). But the Wrangler's on-road behavior is dramatically better than it used to be and is no longer a reason for shoppers to disqualify it from consideration."
