Here's what it'll take to build a Jeep Grand Cherokee Hellcat

Let's get one thing straight: We want a 707-horsepower Grand Cherokee Hellcat to happen. Badly. The latest report from Motor Authority is encouraging; the bonkers SUV supposedly has a codename, Project K, and has been given the green light for production. Fingers crossed. You might be wondering why the Trackhawk isn't already a thing. Hellcat engines exist, SRT Grand Cherokees exist, so just combine the two, right? It's not quite that easy. Here, we outline what needs to happen, why it should be the quickest Hellcat vehicle out there, and why it won't come anywhere near 200 miles per hour. How To Build A Hellcat Jeep The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged V8. The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged Hellcat V8. Breathing is important on two counts: pulling in enough air for the combustion to put out 707 hp, and then cooling the various heat exchangers once the engine is up to temperature. Dodge did it with the Charger and Challenger, it can do it with the Jeep. This is one place where the Grand Cherokee's larger frontal area might be a boon, as it gives the engineers more surfaces through which to suck air. Once you generate the 707 horsepower and 650 pound-feet of torque, it has to get to the wheels somehow. Jeep's current SRT all-wheel-drive system will at least need some beefing up to handle the torque. It could require a more complete re-engineering. We at least know the ZF-supplied eight-speed auto, used in the Dodge Hellcat models, is up to the task. The Hellcat engine should fit in the Grand Cherokee, as it's about the same size as the 6.4-liter currently in SRT Jeeps, but the Hellcat is taller because of its supercharger. The hood may need to be raised or at least resculpted for clearance, as well as to address those cooling needs. Quicker Than Everything, But Not Faster 200 mph? We're skeptical, from both a physics standpoint and a legal one. A reminder of the quick/fast distinction: quick is acceleration, fast is road speed. The Jeep's all-wheel drive will help put the Hellcat engine's power to the ground in a more manageable way than the Charger and Challenger do through just the rear wheels. That means better acceleration times than the Dodges (11.0 seconds in the quarter-mile for the Charger Hellcat, 11.2 for its Challenger sibling).

GMC wants to target Jeep with compact crossover

GMC execs might consider adding a Jeep competitor to the range, but rather than new rumors of a Wrangler-fighter, this time the Professional Grade brand could go after the Renegade. Division boss Duncan Aldred would like to broaden the brand's lineup with a subcompact crossover. "I keep telling everyone, 'How can General Motors' truck brand not be in the fastest-growing segment in the industry, an SUV segment," he said to Automotive News but wouldn't confirm whether the model was under development. General Motors already offers small crossovers like the Chevrolet Trax and Buick Encore, but the CUV segment in general continues to drive auto sales in the US. Adding a similarly sized GMC to the mix might increase the automaker's volume by appealing to different customers. "A GMC buyer is very different from a Buick buyer. This is like comparing the Fiat 500X to the Jeep Renegade. They are very similar but appeal to different people," Dave Sullivan, Product Analysis Manager at AutoPacific, told Autoblog. Aldred started the speculation about a Wrangler-fighting model in an interview in late 2014, and the company reportedly even raised the idea of an offroad-focused vehicle to dealers to see how they reacted. The development process was only in the very early planning stages, but the brand considered using Hummer for a little of the new product's inspiration. Aldred later suggested to journalists the possibility of adding a compact or midsize SUV to the GMC range in the next 10 years to appeal to more buyers. He didn't comment directly on the possibility of the Wrangler-challenger at the time beyond saying: "I can't confirm that ... everything's on the table." Related Video:

These three automotive Lego kits deserve your suppoort

Lego has been quite good to car enthusiasts over the past few years. We've seen traditional kits for the classic VW Microbus, Mini Cooper, and the Caterham 620R, as well as an elaborate Technic kit for the 911 GT3 RS. But why stop there? The Lego Ideas page, which allows users to submit ideas with the chance to see their kits reach production, has many more cool car kits we'd love to see. Check them out below, and be sure to log on to vote for them. If a submission hits 10,000 votes, it is considered for production. That's how we got that Caterham kit, so it's worth your time to show your support. Peugeot 205 Turbo 16 This is a submission aimed at becoming one of Lego's Speed Champions kits. These are very small mini-figure scale car models, and the series has included the Ford GT, Audi R18 Le Mans racer, and more. This kit features a tiny version of the Peugeot 205 Turbo 16, a Group B rally racer that gave Peugeot World Rally Championship titles two years in a row. The kit has a well-executed version of the car and its massive rear spoiler on the hatch. It also comes with a big dirt crest for it to fly over, along with amazed spectators on the sidelines. Porsche 911 Turbo 930 We love the GT3 RS Lego kit, but we think it's a little lonely as the only Porsche kit available. Such an impressive Porsche deserves an impressive companion, like this 911 Turbo. It's the 930 version, which is arguably the most famous classic 911 with its turbocharged power, whale-tail wing, and scary driving dynamics thanks to considerable turbo lag and rear-engine handling characteristics. This model is quite large at 1:10 scale, and comes with a detailed interior and exterior. The best part is the remote-control components underneath that allow the car to be driven. Jeep Wrangler JK Moving off the beaten path again, we have this highly detailed Wrangler kit. Actually, we have two kits, as the creator designed both two-door and four-door versions. They both feature removable hard tops, detailed interiors, and big tires. They also come with an assortment of off-road accessories such as auxiliary lights, an off-road jack, winch, gas can, roof rack, and off-road bumper. You can also find various fluid reservoirs and engine details under the opening hood.
