Sunday Drive: Performance comes in many shapes and sizes

The Chevrolet Corvette has always stood out as a bastion of reasonably priced performance, and the latest 'Vette has that in spades. And while its expected starting price of around $120,000 certainly isn't cheap, it's an undeniable deal in the supercar world – remember, this thing'll do 210 miles per hour thanks to its 755-horsepower supercharged V8 engine. And did you get a load of that massive rear wing? Team Corvette's longtime foe, the Porsche 911, is similarly hellbent on ultimate performance. And as a reminder of how long the Corvette/911 rivalry has been melting tires we present the 1990 Porsche 911 as reimagined by Singer you see below. It's beautiful, it's green, and it's packing 500 air-cooled horsepower. You don't have to burn gasoline to go fast, as proven by the second-generation Tesla Roadster, which was revealed as a surprise late last week. Elon Musk says it'll be the quickest car in the world with a 0-60 time of just 1.9 seconds. And while you may not think of a semi truck when you think speed, the Tesla Semi can do 0-60 in 5 seconds flat unloaded, or in 20 seconds with a load of 80,000 pounds. Compared to today's crop of diesel semis, that's amazing. Continuing the truck theme, we present an artists rendering of what the next-generation Ram 1500 pickup may look like. Spoiler alert: Ram's mini-semi look is giving way to something much more modern. There may even be a first-of-its-kind split tailgate at the rear. And if you don't think the Ram 1500 has anything to do with performance, we should remind you that it's one of the cheapest ways to get a tire-shredding Hemi V8 engine in America. 2019 Chevy Corvette ZR1: All hail the 755-horsepower C7 king This is the first Porsche 911 to get Singer and Williams' 500-horsepower engine Tesla Roadster surprise reveal | 'Quickest car in the world' Tesla Semi Truck revealed: Here are the key details This could be the next-generation 2019 Ram 1500 2019 Ram 1500 spotted with split tailgate

2019 Ram HD Chassis Cab trucks: tough on the outside, comfy on the inside

The past year or so has been big for Ram. FCA's truck division went from having some of the most dated (though still solid) pickups on the market to introducing the 2019 Ram 1500, arguably the new segment leader. A year later, at the 2019 Detroit Auto Show, FCA revealed the new Ram Heavy Duty. Yesterday, Ram announced the 1500 was getting a trick tailgate to compete with the power tailgate on the Chevy Silverado and MultiPro tailgate on the GMC Sierra. Today, at the 2019 Chicago Auto Show, FCA will present the new Ram 4500 and 5500 chassis cab models. Like the Ram 2500 and 3500, the new chassis cab trucks appear to share a lot with the current crop of Ram HD trucks. The cab itself appears to be unchanged from the outside, though the front fascia has been updated to reflect Ram's current design. As with most things, it's what's inside that counts. The chassis cab models get the fantastic interior from the 2019 Ram 1500. It's a handsome and well-appointed cabin. Even base Tradesman models benefit from the new design and packaging. There's new tech, too. The 12-inch infotainment screen is nice to look at, but customers are likely to enjoy features like adaptive cruise control, forward collision warning and automatic emergency braking (with trailer brakes). The safety tech is available on all trim levels. The trucks also pack parking assist and a 270-degree camera view. There are also camera features to help hook up trailers (including fifth-wheel goosenecks). The Ram Chassis Cab 3500, 4500 and 5500 represent Class 3, 4 and 5 GVW ratings. As such they pack some punch under the hood. The standard engine is the 6.4-liter Hemi V8 making 410 horsepower and 429 pound-feet of torque, though 4500 and 5500 models only make 370 horsepower. The Ram 3500 features cylinder deactivation to improve fuel economy. The three trucks are available with a 6.7-liter Cummins turbo-diesel inline-six. The engine makes 360 horsepower and 800 pound-feet of torque. An Aisin six-speed auto is available on V8 models and standard with the diesel. Both engines are available with dual alternators. The trucks are available in four industry-standard frame lengths measured in inches from the cab to the rear axle: 60, 84, 108 and 120. Upgraded brakes should shorten stopping distances and improve pedal feel. Thanks to high-strength steel and aluminum, the truck should weigh about 120 pounds less than before.

All hail the Hellephant, Mopar's 1,000-horsepower crate engine

It's shocking to say this, but the all-powerful Dodge Demon looks weak now that Mopar has unleashed the Hellephant. This crate motor makes 1,000 horsepower and 950 pound-feet of torque, and its name is a combination of the nickname for the old 426-cubic-inch Hemi V8 and, obviously, the Hellcat. This monster is a 426-cubic-inch version of the current third-generation Hemi V8 topped by a supercharger similar to what the Hellcat line packs. Everything is cranked up to — or perhaps, past — 11. The engine block is made of aluminum and weighs 100 pounds less than the equivalent iron block. All of the internals are forged. The stroke and bore have been increased. The supercharger produces 15 pounds of boost and displaces 3 liters; more than the 2.7-liter blower on the Demon and the 2.4-liter blower on the Hellcat. And as big and powerful as it is, it will still rev to 7,000 rpm. It's a thoroughly monstrous motor, but shockingly, it won't be that difficult to live with. For one thing, Mopar will offer a complete kit to get the engine up and running, including an engine computer, wiring harness and drive-by-wire throttle. It also runs on 93-octane pump gas. That's especially amazing considering the Demon engine "only" makes 840 horsepower, and that's on race gas with 100+ octane fuel. It also has us wondering what the Hellephant could make on racing fuel. The Mopar folks did say that there's room to add more power. Pricing wasn't announced for the Hellephant engine. The Hellcat crate engine retails at $19,350 directly from Mopar, so it's safe to assume that the Hellephant will go for more. The installation kit with the computer and harness will be an extra charge of likely over $2,000, based on the Hellcat kit. The engine and the kit will be available in the first quarter of 2019.
