Jeep Grand Cherokee

Leave a comment

The plug-in hybrid powertrain within the Grand Cherokee consists of a 2.0-litre four-cylinder turbo petrol engine making 270bhp and 295lb ft, two electrical motors and a 17.3kWh (15.0kWh usable) battery pack.

The predominant motor is a 134bhp, 195lb ft unit mounted inside the eight-speed computerized gearbox, between the clutch plates and the gears. This is what drives the automobile when you choose EV mode and permits gearchanges and swapping into the low set of ratios simply as if you have been driving on petrol.

Then there’s a 48V built-in starter-generator on the entrance of the engine, making 39bhp and 44lb ft. It’s  obtainable to spice up low-end torque however primarily to start out and cease the petrol engine and cost the battery when the automobile is stationary and in gear.

With a full battery, efficiency is powerful. With whole outputs of 375bhp and 470lb ft and the principle electrical motor pitching in from relaxation, the 0-62mph time is simply 6.3sec. Sometimes, although, the motor and petrol engine take a second to resolve who’s doing what, so the latter will spin up audibly, and typically on again roads it’s preferable – and never unsatisfying – to take management of the gears your self. If you do go for a full-on burst of acceleration, you’ll be able to anticipate pretty coarse engine noise too.

However, even with 1 / 4 cost within the battery, efficiency is degraded noticeably. The coarse four-cylinder turns into a relentless presence, revving excessive and infrequently, returning solely common efficiency and MPG figures within the low 20s. The gearbox turns into fairly clunky too.

Off-road notes

The Grand Cherokee’s off-road credentials are fairly spectacular, as you’d anticipate. On all variations besides the entry-level Limited, there’s air suspension as normal with 5 totally different peak settings and as much as 275mm of floor clearance. Its most strategy angle is 28.2deg, breakover angle 20.9deg and departure angle 30deg – much like the Discovery.

Jeep has a path score for its automobiles: the three-door Wrangler scores the utmost 10, the Grand Cherokee six or seven, relying on the variant. It’s additionally an affordable tow automobile, with a most braked trailer load of two.2 tonnes (2.3 tonnes for a drawbar trailer), however the Range Rover Sport PHEV and Mercedes GLE PHEV will each tow usefully extra.

Off street, it’s terrific. The pretty factor is which you can stick it in EV mode and do all of your driving that method. Because the motor is on the gearbox facet of the clutch, it pulls off extremely easily and with out hesitation, plus with all of its obtainable torque from relaxation.

And as with most correct 4x4s, you’ll in all probability run out of bravery – particularly at this value – earlier than it runs out of skill. We had it on a facet slope exhibiting greater than 30deg, and if there wasn’t a Jeep bod on standby telling me that was high-quality, we might have satisfied ourselves it was going to tip over. In different phrases, a winter shoot or the typical horse yard treacherousness are issues that the Grand Cherokee will deal with simply high-quality.

Lamborghini Concept Teaser Video Offers Sneak Peek Before August 18 Debut

Lamborghini has released a new teaser video for their upcoming concept vehicle, giving viewers a glimpse of its futuristic design. The model is set to make its debut on August 18 during the Monterey Car Week in California.

The 15-second video begins with an aerial shot of a city, then transitions to a woman lying on a circular platform, gazing at a star-filled sky through a skylight. Next, an object is seen flying through space before descending to Earth. Finally, the Lamborghini appears, with its headlights illuminated.

Another image of the concept vehicle shows stacked horizontal headlights that tilt inward. The ride height appears to be taller than most performance cars, with significant light visible underneath. However, the model does not resemble an SUV.

The Lamborghini concept features a flowing roofline and smooth side styling, but with sharp edges in the greenhouse area. There are subtle creases below the beltline at the front and rear of the vehicle.

In a previous announcement, Lamborghini referred to this concept as the “first prototype of our fourth series production car.” The company’s CEO, Stephan Winkelmann, stated that the road-going version would be a 2+2 grand tourer and more practical for daily use than the Huracan replacement or the new Revuelto.

The teaser video includes the phrase “What if…,” leaving viewers to speculate on its meaning. One possibility is that Lamborghini might be hinting at the idea of building an electric vehicle.

No specific details about the concept or the production Lamborghini EV have been revealed, including any shared components with other VW Group electric models. The production version of the concept is scheduled to be released in 2028, making this teaser our first glimpse of a vehicle that is still several years away.

Tesla’s Dojo Supercomputer Begins Production To Train Autopilot Worthy Of Its Name

Tesla is stepping up its game with the production of its new supercomputer known as Dojo, designed specifically to train the Autopilot system. Currently, Tesla relies on a supercomputer equipped with Nvidia A100 GPUs, composed of 5,760 GPU units spread across 820 nodes. This powerful setup can deliver 1.8 Exa-FLOPS (floating point operations per second). However, the Dojo supercomputer is expected to surpass these specifications easily.

Unlike the current setup, Dojo doesn’t depend on outsourced cores. Instead, it utilizes a self-designed D1 chip, manufactured by TSMC using a 7nm fabrication process. This chip contains more than 300 computing cores, and multiple D1 chips are clustered to form tiles. Each System Tray is made up of six tiles, and one cabinet consists of a pair of System Trays. To create one ExaPOD, ten cabinets are combined.

During Tesla’s AI Day event last year, a detailed presentation on Dojo was provided, shedding light on its architecture. The primary goal of Dojo is to expedite the auto-labeling process, which plays a vital role in training the Autopilot model. By enhancing the speed of this process, Dojo enables the Autopilot system to better recognize real-world objects and understand various scenarios, ultimately leading to more accurate decision-making.

However, even during the early stages of testing, Dojo’s power was so overwhelming that it reportedly overloaded the local power grid. This demonstrates the high potential and impressive capabilities of Tesla’s new supercomputer.
