2024 Jeep Grand Cherokee L Hurricane Engine: Will Grand Cherokee Get Hurricane Engine? – Jeep’s legendary mid-size SUV has been out for less than 2 years, and already some new features are being added to the Grand Cherokee 2024. According to what we’ve learned so far, the time has come for upgrades in powertrains. It’s now time to turbocharge the current models. They are available in V8 and V6 naturally aspirated units. The new Grand Cherokee, like the Wagoneer, will benefit from the Hurricane six-cylinder engine. It offers plenty of power and efficiency.
We don’t think that the 2024 Jeep Grand Cherokee will bring any other significant changes. Expect a familiar look, along with the same characteristics and features. The SUV is a great vehicle with a smooth ride and excellent off-road capabilities. It also has luxurious interiors.
We don’t think it will arrive any earlier than normal, despite the possible engine upgrade. It’s expected to arrive in the fourth quarter. 2024 Jeep Grand Cherokee L Hurricane Engine
Engine
Under the hood, the biggest innovations for next year will be revealed. Three new engine options will be available for the 2024 Jeep Grand Cherokee. According to what we have learned so far, Jeep is going to be getting the Hurricane engine very soon. The 3.0-liter inline four with twin turbos will likely be available in either 510 or 420 horsepower. This is likely to be the new V8. The engine will have more power, torque, and better fuel efficiency.
A hybrid model is also expected. The model will use the same 4xe powering Jeep Wrangler. This system uses a turbo-four 2.0-liter with an electric engine to produce 375 horsepower. We can also expect a good all-electric driving range of over 25 miles.
Base models, on the other hand, will remain with the familiar 3.6-liter engine. All engines are paired with an eight-speed transmission.
The fuel is delivered via direct injection and high-pressure pumps. In comparison to the Hurricane 420 hp, the High-Output Version uses two pumps. This increases the fuel pressure for the Single Fuel Rail System up to 5,075 PSI. The cylinder head integrated exhaust manifold is equipped with two twin-scroll Turbochargers. Charge air feeds into the intercooler on the intake side. The hot and cold side of the Jeep I-6 engine is the opposite.
The water-to-air intercooler is placed on the intake side to ensure the charge has the shortest possible path between the outlet of the compressor and the throttle and also avoids it being oversaturated during compression. Intercooler uses less than three-quarters of a gallon, and turbo housings cool along with the engine. The two catalytic convertors used for emission control are attached to the turbos by V-bands. For the Hurricane standard output, an EGR upstream system is also required.
On both Hurricanes, boost control is controlled by internal wastegates that are servo-actuated. Each turbo serves three cylinders to ensure quick acceleration. Jeep claims that each Hurricane version has a unique turbo, but did not provide any specifics other than the fact that the turbos on the standard output are smaller. The standard and high-output Hurricanes have different intake systems, and their turbos use a unique intercooler. (The charge pipes on high-output models are separated until they enter the intercooler; on standard, they are joined much earlier.) Standard and high-output Hurricanes have different boost tubes that connect the turbo to the throttle. The standard version has smaller ones.
There are, in total (not including fasteners), 96 parts that can be shared between both versions of Hurricane’s 3.0-liter Twin Turbo I-6. There are almost as many parts (72) that are unique to the engine with 510 hp and 90 for the 420 hp.
After explaining the differences, we can now discuss what causes the standard-output engine to generate 420 horsepower at 5,200 revs and 468 lb.-ft. of torque at 3500 revs and what makes it possible for the high-output engine to deliver 510 hp and 500 lb.-ft. at 3,550 rpm.
The standard version uses the same dimensions for the bore and the stroke, but relies instead on cast aluminum pistons with a compression ratio of up to 10.4:1. It is limited electronically to 5,800 revs and “only” make 22 psi boost pressure. However, it can also use regular or 89-octane. The quoted figures for 420 horsepower at 5,200 revs and 468 lb.-ft. of torque are generated with mid-grade oil. Standard output I-6 uses viscosity 0W-20 oil.
Hurricane’s 510-hp, high-output engine uses aluminum pistons with a compression ratio of 9.5:1. This is almost a full-CR difference in piston design. Its electronically-limited speed of 6,100 rpm produces a 26 psi boost. It’s also stuck with 91-octane premium gasoline; an oil viscosity of 0W-40. Each engine uses different coils and injections, which are likely responsible for differences in boost pressure (the higher-output engines lack EGR) and combustion.
Fuel consumption is different between the two engines in Wagoneer Ls. The rear-wheel drive Wagoneer L equipped with the 420 hp Hurricane is estimated by the EPA to deliver 17 mpg in the city, 24 mpg on the highway, and 20 mpg when combined. This allows the 30-gallon tank of fuel to last more than 732 miles before requiring a fill-up. The Wagoneer L loses about 30 highway miles and 1 mpg when adding four-wheel driving. The Hurricane’s 392-hp, 5.7-liter engine is still more fuel efficient. It is rated at 15-16 mpg in the city, 20-22 on the highway, and 17-18 combined.
The EPA’s estimates drop to just 14 mpg in the city and 19 mpg on the highway (compared to 17 mpg for the non-L). 16 mpg is the combined figure. The L gets just over 580 miles. The high-output I-6, which is essentially replacing the 471-horsepower 6.4-liter V-8, delivers 13 mpg in city traffic, 18 on the highway, and 15 in combined driving. While the Hurricane’s EPA numbers aren’t much better than those of its eight-cylinder competitors, it is still more powerful.
The new Grand Wagoneer L and Wagoneer L with longer wheelbases are more heavy than the shorter-wheelbase models. RWD Wagoneer L has a factory curb weight of 6,100 pounds, which is within the range of 7,400 GVWR. A loaded Grand Wagoneer L Series III weighs in at a staggering 6,700 pounds, which puts it in the 7,950 GVWR range. These figures are just a small sample of the Jeep Hurricane engines’ workload. And that is before their rated payloads, which range from 1,410 pounds for Wagoneer L and 1,330 pounds for Grand Wagoneer L Series III. This extra weight is also the reason why the Grand Wagoneer L’s trailering capability of 9,450 pounds in the Grand Wagoneer L Series III lineup, is the lowest.
Changes
We don’t think that the 2024 Jeep Grand Cherokee will bring any other significant changes. The layout will be the same as it was a few months ago. This new generation, which is built on Giorgio’s platform, is more agile and lighter than its predecessor. Jeep engineers were able to maintain the off-road capability at the previous level. The Quadra Trac II system and adaptive air suspension can be added to the Grande Cherokee, making it one of the most capable off-roaders among midsize SUVs.
The Grand Cherokee has evolved in terms of its design. It’s still the same seven-slot design but in a more bold and prominent version. We don’t anticipate any significant changes for next year, as the vehicle appears more muscular. We won’t rule out minor changes like new colors or special editions.
Interior
The cabin should not undergo any major changes, just like the exterior. The interior of this SUV is very luxurious. This SUV combines fine aesthetics, high-tech features, and luxurious materials. The cabin is more luxurious than most competitors thanks to this combination.
It is well-built and offers plenty of room. The two rows of seats are spacious and can easily accommodate an adult. The front seats are very supportive and massive, with a good driving position. There is a three-row stretched version for those looking to add more seats.
This isn’t an impressive SUV when it comes to the cargo space. Comparable SUVs like the Toyota Highlander or Chevy Traverse have more space. In 2024, the Jeep Grand Cherokee offers nearly 38 cubic feet behind the 2nd row of seats and approximately 70 cubic feet for the entire cargo space.
It won’t surprise us if there are new features available and standard. Even if this happens, there won’t be anything new. The majority of features should be the same, including a 10.25″ digital instrument panel, an 8.4″ touch screen, Apple CarPlay, Android Auto wireless, USB ports and Bluetooth, six speakers, USB and Bluetooth connections, and dual-zone automatic climate control with push button start.
There are a number of available options, including a 10.1″ touchscreen, a 10.25″ touchscreen on the passenger side, navigation, wireless charging for devices, an Alpine 9-speaker audio system, or a McIntosh 19-speaker audio system. Other upgrades include HD Radio, Satellite Radio, and a Rear Seat Entertainment System. On the list of available options are also a quad-zone climate control system, dual-paned panoramic sunroofs, and remote starting. Some of these options could be included in the standard features.
