Is the EV mode of the Jeep Wrangler 4xe good?

The· 2021 Jeep Wrangler 4xe Next to the mighty person Rubicon 392 In terms of power: 375 hp and 470 lb-ft torque (actually ties 392) from a 2.0 liter turbocharged in-line 4-cylinder and an electric motor packed between the engine and transmission. In short, it’s a fast jeep, clocking at 5.5 seconds, 0-60 mph, efficient (like the Wrangler goes), and has a 49MPGe rating from the EPA. However, there is a big caveat there. Its flashy EPA number applies only to electrical mode.

If you run out of battery and drive it like a regular hybrid, the total number drops to 20 mpg. This is worse than most non-hybrid Wrangler trims and actually worse than some of them. Diesel Rubycon gets a total rating of 23mpg. Therefore, in order for 4xe to make sense for reasons other than its strap horsepower (which we admit to be justified in itself), we need to use its EV mode on a regular basis. The question is whether the 4xe electrical mode is good.

Car and driver

Some plug-in hybrid vehicles have a robust EV mode, like short-range electric vehicles (see “Chevrolet Volt Far Away”), while other plug-in hybrid vehicles have an EPA number of geese. Looks like a Rube Goldberg scheme that is eligible for tax deductions ( Mini Cooper SE Countryman All4 Plug-in Hybrid). The Wrangler is on the stubborn side. Its approximately 14.0kWh battery pack is suitable for an EPA-rated 21-mile electric range and has sufficient capacity to be eligible for a $ 7,500 federal EV tax credit. And the motor is reasonably sturdy, producing 134 horsepower and 181 lb-ft of torque.

Some plug-ins place an electric motor on one of the axles to achieve all-wheel drive (Mini, Volvos), while the Wrangler is mounted in front of a transmission that takes advantage of the benefits of an 8-speed automatic transmission. Increasing ratio. Its position also means that EV mode can power all four wheels even with low range four-wheel drive. Despite the traditional knowledge that EVs do not require multiple gears, EVs do require multiple gears. Also, unlike the Chrysler Pacifica PHEV cousin, the plug-in Wrangler gives the driver the option to dictate the powertrain’s operation by choosing between hybrid, EV, or battery-saving modes. In EV mode, it stays in EV mode until you put it on the floor or the battery runs out.

Due to all the advantages of its layout, the 4xe EV mode gives us a 5318 lb Wrangler Bicon with less horsepower than the 2002 TJ generation 4-cylinder. Is it okay to drive? Surprisingly: Yes. Now let’s get down to the important questions.

How slow is it?

0-30 mph isn’t too bad, reflecting the punchy relative EV mode around the town.

Offline, I find 4xe reasonable. It’s a great way to explain it. The area around the town is fine. A Very informal Acceleration showed a time of 0 to 30 mph in less than 6 seconds, from which acceleration is dramatically reduced. It takes 1-2 miles from 50 mph to 60 mph, and the time from 0 mph to 60 mph should be close to 20 seconds. Even from rest, the digital speedometer doesn’t accelerate so fast that it has to skip numbers. But above 50, you can see each digit better. In low gear, it’s catching up with traffic. You can also cruise at highway speeds as long as the battery allows. It will take some time to get there.

The 4xe actually has two electric motors, but the second motor (44 hp and 39 lb-ft torque) can’t help the cause in EV mode. This is because the starter generator is connected to the crankshaft pulley. Therefore, if the ICE engine is dormant, you will be out of the game.

Can you tow?

Yes, I can. Connect a 12-foot utility trailer and 2021 Polaris RZR Trail (1238 lbs, dry) and Honda TRX90X (£ 262). Together with the trailer itself, the total weight was about 2000 pounds. It weighs literally a ton, more than half the Wrangler’s 3500-pound traction rating. And although the 4xe was even slower, it constantly carried the burden on steep hills and backstreets over 55mph without asking for help from the four-cylinder. The range dropped sharply, probably twice as fast as normal, but the 4xe does allow towing in local EV mode.

Is it possible to burn out?

What you can’t do with Rubicon 392: Rear-wheel drive burnout.

Yes, it has an asterisk. Unlike the Rubicon 392, the 4xe full-time transfer case includes a two-wheel drive mode. So I set it to rear-wheel drive, turned off traction control, turned on EV mode, and held the brakes while adding gas. .. .. It was pulled apart smoothly. There is no way for an electric motor to overcome the rear brakes on the brake stand. Also, it does not have the power to bark the tire alone. But it’s on the pavement. To get dirty? Yeah, it roasts them so that the two KO2 size trenches on my driveway can prove. I think this was my first EV dirt burnout, but I’m a maniac, so I flushed the Mitsubishi iMiev out of the driveway.

Can you offload?

This may be the most important point for some Wrangler 4xe owners. It’s the ability to quietly offload. And in this regard, the 4xe Rubicon is as sturdy as any other Rubicon: 30-inch water column capacity, front and rear differential locks, and electronic disconnection of the front sway bar. I sneaked it up in EV mode, and the technical trail running limits-low speed and accuracy are rewarded-in sync with the powertrain’s electrical capabilities.

But if you’re trying to hit a dune in Glamis or try a bounty hole in your local Tuff Truckz Mud Fiesta, launch that Turbo 4. EV mode is convenient, but it’s useful to know that it has 375 horsepower when you need it.
