C7 Corvette turbo with 1,000 horsepower promised from Hennessey

If you can't wait for the next-generation Chevrolet Corvette ZR1, Hennessey says they will have you covered. The Texas-based company has announced it will offer a spate of upgrades for the 2014 Corvette ranging from a range of bolt-on options all the way up to a 1,000-horsepower, twin-turbo system. Buyers can start with a cold air intake, cat-back exhaust or stainless steel long-tube headers, but Hennessey says it will also offer up three stages of forced induction mayhem should those bits and baubles not provide enough thrust.
Those choices start with a supercharger system good for up to 700 hp, though Hennessey will gladly ditch the blower in favor of two turbos. Doing so will spin the crank to the tune of 800 horsepower all the way up to a certifiably ludicrous 1,000 ponies. There's no word on how much these tricks will cost you - or when they will be available, as we're guessing they haven't gotten their hands on the car yet - but you can head over to the Hennessey site to drop them a line if you're curious.

Jaguar I-Pace vs. Tesla Model 3 and other EVs: How they compare on paper

The 200-mile club of electric vehicles is really growing. The most recent member is the Jaguar I-Pace, the company's first pure EV. It promises luxury, performance, style, and most important, good range. Nearly as recent is the Hyundai Kona EV, and while it doesn't promise luxury or performance like the Jaguar (it's also smaller), it does pack impressive range. With the introduction of both of these electric cars, we thought we would see how they compare against each other, and the other two big names in high-capacity electric cars: the Chevy Bolt EV and the Tesla Model 3. This isn't intended to be a direct, apples-to-apples comparison, as the four are quite different. If anything, they break into two groups: bigger and more luxurious, and smaller and less expensive. Then again, the number of vehicles with this electric range is small and comparisons to EV's with less range wouldn't be too kind to the other guys. If you want to learn more about these EVs, and compare them with other cars, be sure to check out our Car Finder and comparison tools. Horsepower and torque There is one clear winner here, and that's the Jaguar I-Pace. It packs a whopping 394 horsepower and 512 pound-feet of torque. That comes through a pair of electric motors (one at the front, another at the rear) that provide the Jag with all-wheel drive, the only one of these vehicles to offer it (at the moment). Altogether, it allows the I-Pace to have the best 0-60 mph time of 4.5 seconds. At the other end of the spectrum is the Hyundai Kona EV. It's front-drive, like the Bolt EV, and has effectively the same amount of horsepower as the Chevy at 201 horsepower, but its 0-60-mph time is almost a second slower. And the low-range version of the Kona, excluded because it doesn't go more than 200 miles between charges, is slower still. The Tesla Model 3 is the only vehicle with rear-wheel drive, and with a 0-60 mph of 5.1 seconds for the Long Range model, it is still very quick. Range and energy use Frequently, the all-consuming question with electric cars is, "How far can I go on a charge?" And to go the farthest, you need the long-range Tesla Model 3. It can go 310 miles. It has the added advantage of being able to use the network of Tesla Supercharger stations, though they are pay-per-use with the Model 3. Even the lower capacity Model 3, with just 220 miles of range, can use these stations.

Diesel details: Comparing Ram 1500 EcoDiesel, Chevy Silverado Duramax, Ford F-150 Powerstroke

With specifications for the 2019 Ford F-150 Power Stroke diesel already out, and the details on the 2020 Ram 1500 EcoDiesel and Chevy Silverado Duramax (and its GMC Sierra twin) trickling out, we felt it was a good time to start comparing the full-size trucks' light-duty diesels. Bear in mind, we've only driven one of these new diesel trucks, so we'll be sticking to numbers for now. Some numbers haven't been announced yet, either, but stay tuned, because we'll be updating this post with additional specifications as they become available. And if you want to compare any other versions of these trucks with other vehicles, be sure to check out our comparison tool. Now let's start comparing, starting with our big chart of numbers below. As we can plainly see, these trucks are quite closely matched. Each one has six cylinders, a displacement of 3.0 liters and a turbocharger to boost it. The output of each is somewhat close, too. The Ram 1500 EcoDiesel is the torque king at 480 pound-feet, 20 more than the GM trucks and 40 more than the Ford. The GM trucks win on power, though, with 277 ponies, 17 more than the Ram, and 27 more than the Ford. GM does report that you get their trucks' peak 460 pound-feet of torque from 1,500 rpm to 3,000 rpm, whereas the others only report peak torque at a particular point in the rev band, but all of these trucks should have wide, flat torque curves as you would expect from modern turbodiesels. 2020 Ram 1500 EcoDiesel View 8 Photos Engine output is only one part of the truck performance equation. We also have towing and payload capacity, as well as fuel economy. With towing, the Ram 1500 is the current leader with a maximum capacity of 12,560 pounds. That tops the Ford F-150's 11,400-pound tow rating by well over 1,000 pounds. The F-150 can carry 2,020 pounds in its bed, but we don't know yet whether that's better or worse than the Ram or the GM trucks. We also don't have numbers for the GM trucks' towing capacities. View 9 Photos As for fuel economy, the Ford F-150 manages a thoroughly impressive 22 mpg in the city and 30 on the highway with two-wheel drive. Choosing four-wheel drive drops those numbers to 20 and 25 respectively. The fuel economy numbers for the Ram, Chevy and GMC haven't been revealed yet, but for some comparison, we can look at the old Ram EcoDiesel. That truck's best fuel economy was 20 in the city and 27 on the highway with two-wheel drive.
