FCA Vehicles Benefit from New Engine and eTorque
Now that the 2018 Jeep Wrangler JL is here, a lot of new consumers are coming to check it out, and not just because of its off-road capabilities and performance. Not only does the new model have a number of exterior and interior changes, but the powertrain has received a noticeable upgrade, or two. For one thing, the Fiat Chrysler Automobile Group has developed a new future-proof engine said to be the replacement for the original “World Gasoline Engine,” the naturally aspirated Tigershark engine. Throw the new eTorque system into the mix, and the 2018 Jeep Wrangler has a new and improved fuel economy standard, and consumers are finding it exciting.
Future-Proof Engine in FCA Vehicles
The future-proof engine developed by the Fiat Chrysler Automobile Group is, in short, a turbocharged 2.0-liter Inline 4-cylinder engine. This engine popped up in the 2018 Jeep Wrangler JL when it debuted at the 2018 Los Angeles Auto Show, and is now not only an option on the 2018 Jeep Wrangler JL, but also on the 2019 Ram 1500 and 2019 Jeep Cherokee. Before we talk too much about it though, let’s back up.
There are three engine options* available on the 2018 Jeep Wrangler JL lineup. The standard engine is the popular Pentastar V6 engine, able to generate 285 horsepower and 260 lb.-ft of torque, returning to the 2018 model year with some changes. The Pentastar V6 was modified for the new Wrangler JL and now the engine is equipped with Engine Stop-Start (ESS), which helps to conserve fuel economy, and paired to a six-speed manual transmission. Both of the changes to the engine resulted in a fuel economy of 17 mpg in the city and 23 mpg on the highway. The engine is also available with a class-exclusive eight-speed automatic transmission, and that increases the vehicle’s fuel economy to 18 mpg in the city.
Then take a look at the second engine option – the 2.0-liter turbocharged inline-4 cylinder engine paired to an eight-speed automatic transmission. The Fiat Chrysler Automobile Group knows consumers want power, but they also want good fuel economy. This new “Global Medium Engine” out performs the Pentastar V6 engine, able to generate a best-in-class 270 horsepower and 295 lb.-ft. of torque. Not only does the engine provide excellent power, but it also has a great fuel economy of 23 mpg in the city and 25 mpg on the highway. The great power and fuel economy are largely attributed to a completely new invention FCA introduced this year, a 48-volt Belt Start Generator system known as “eTorque.”
eTorque and FCA Vehicles
The eTorque system, as far as we can know so far, will be available on the 2018 Jeep Wrangler JL and the 2019 Ram 1500 going forward. This eTorque system, in a sense, turns the powertrain of the vehicle it’s installed in into a pseudo-hybrid system. With most hybrids, the main output of horsepower comes from the engine, whilst an electric motor powered by a lithium-ion battery gives it a boost. Instead of an electric motor though, the eTorque system is there, able to offer hybrid functions such as auto stop/start, electric power assist, extended fuel shut-off, transmission shift management, intelligent battery charging, and regenerative braking.
That’s not all though. The eTorque system is a new mid-hybrid system that increases fuel economy and produces more torque, able to generate an additional 90 lb-ft of torque in addition to the original output of the Pentastar V6 engine, 260 lb-ft of torque, with little-to-no effort at all. As we know, torque is what turns the wheels of an engine and gets it moving – with the engine having less work to do to produce that torque and turn the wheels, that leaves us with a less stressed engine, and thus, a higher fuel economy.
As noted, this eTorque system is also found on the 2019 Ram 1500. Aside from helping with fuel economy, eTorque also helps with towing power. Like the Pentastar V6 that gets an additional 90 lb-ft of torque, the 5.7-liter V8 HEMI engine receives an additional 130 lb-ft of torque for a total of 530 lb-ft of torque. It’s no wonder the max towing capacity of the 2019 Ram 1500 is 12,750 pounds.
Increasing power, towing capability, and fuel economy? The Fiat Chrysler Automobile Group sure is on top of things. Check out these new improvements for yourself at Aventura CJDR with a test-drive of the 2018 Jeep Wrangler JL or the 2019 Ram 1500.
