2016 Dodge Viper ACR First Drive [w/video]

The Dodge Viper is not a comfortable car. Livable, yes. The interior is covered in fine materials. But you still climb over a hot door sill to enter the tiny cabin. And the frequency range of the engine's noises seem specifically designed to cause headaches. What happens, then, if you remove all pretense of civility from a Viper and add equipment solely aimed at improving lap times? You would have the 2016 Dodge Viper ACR. In terms of achieving its purpose, this car is a absolute success. In many ways it's also the most honest Viper of the current generation. Prices start at $121,990 (including $2,100 gas-guzzler tax and $1,995 destination), or $32,900 more than the least expensive Viper. In ACR trim, the Viper loses the under-carpet padding, 9 of 12 speakers plus amplifier, carpet and trim from the cargo area, and sound deadening in front of the rear wheel wells. The parts of the interior still covered add healthy amounts of Alcantara or optional carbon fiber. That weight loss is compensated by the addition of go-fast bits like the giant rear wing (or the larger "x-wing" on the Extreme Aero Package), 10-way adjustable Bilstein Motorsports shocks, Brembo carbon-ceramic brakes, a rear diffuser, and a front splitter. Total claimed curb weight is 3,392 pounds in Aero trim (standard ACR trim is 18 pounds lighter), which is within a few stone of the rest of the Viper lineup. The diffuser strakes and leading edge of the splitter are removable, made to be replaced after rubbing on track tarmac and make street driving slightly more practical. Not that you'd want to drive the ACR on the street, with the lack of noise insulation and spring rates twice as stiff as the Viper TA, but it is street-legal. Dodge claims the DOT-approved Kumho Ecsta V720 tires on the ACR allow faster lap times than some race compound tires. Our test was limited to on-track shenanigans at Virginia International Raceway. Which is fitting because we wouldn't have anything good to say about driving the car on the street. The ACR is, essentially, a race car sold in the showroom, although with the Viper's 1 of 1 customization program, your custom build can include as many creature comforts as you like. Lined up in pit lane at VIR, the Viper ACRs for our evaluation blur the air with heat shimmer. All of the test cars have air conditioning, but that shuts off at full throttle with a six-second reset.

Values snowball for legendary Tucker Sno-Cats, latest toys of the super rich

Here's a fun-sounding vehicle perfect for the cold and snow that's currently gripping much of North America. Tucker — no, not that Tucker — just marked its 75th anniversary making the Sno-Cat, its orange-painted, four-tread snow vehicles that have inspired backcountry skiers, collectors — and increasingly, the super rich. Bloomberg in a recent story writes that demand for the Medford, Ore.-based company's products is soaring on demand from the wealthy, who need a way to get to their backcountry mountain retreats. They're also in demand from collectors and gearheads who also love snow, like two anonymous collectors who are believed to have amassed more than 200 vintage Sno-Cats. The value of vintage models has reportedly tripled in the past five years to well over $100,000 for a fully restored rig. Tucker Sno-Cat Corp. claims to be the world's oldest surviving snow vehicle manufacturer, launched by E.M. Tucker in 1942 out of a desire to design a vehicle for traveling over the kind of deep, soft snow found in the Rogue River Valley of his childhood. It was four Tucker Sno-Cat machines that helped English explorer Vivian Fuchs and his 12-man party make the first 2,158-mile overland crossing of Antarctica in 1957-58. While many of the company's competitors either shuttered or adapted to serving ski resorts with wider, heavier treads, Tucker has stuck to its formula of making lightweight vehicles to travel over deep snow. Many Tuckers use Chrysler's flat six-cylinder engine, or its Dodge Hemi V8 for larger Sno-Cats, mounted rear or centrally, with basic, no-frills aluminum cabins. Sno-Cats all have four articulating tracks that are independently sprung, powered and pivoted at the drive axle. Track options come in three different types: conventional steel grouser belt track, rubber-coated aluminum grouser belt track, and one-piece all-rubber track. Steering is hydraulically controlled by pivoting the front and rear axles for smooth movement over undulating terrain with minimal disturbance of the ground cover. The company today makes 75 to 100 Sno-Cats a year for customers including the U.S. military, oil-drilling crews in cold places like Alaska and North Dakota, and utilities. But demand is so high that it's launched a profitable service reselling and refurbishing old machines. E.M. Tucker's grandson, Jeff McNeil, now head of this division, scours Google Earth for abandoned Sno-Cats rusting in backyards that he might be able to acquire and fix up.

Stellantis aims to eliminate separate inverter, charger to improve EV efficiency

Stellantis has announced that, in collaboration with French battery company Saft and French National Center for Scientific Research, has made significant progress in eliminating two major components of an electric vehicle powertrain: the on-board charger and the power inverter for the motor. The company claims that doing this will allow for better space use in vehicles, as well as improvements in efficiency, cost and reliability of components. As a quick primer, also explained in the below video, the on-board charger and power inverter are sort of translators to get the right current to different parts of the electric powertrain. The on-board charger takes AC power from the grid and converts it to DC to charge the batteries. Then when power goes from the batteries to the electric motor, the power inverter converts that DC power back to AC. These components aren't exactly small. Frequently you'll find them packaged somewhere under the hood. What Stellantis and its cohorts have developed, and have been using on a test vehicle since last summer, are small power inverter boards that can be mounted very closely to the battery packs. They can handle both conversion needs, for charging and discharging, instead of needing two separate devices. The most obvious perk to this is that you can do away with those traditional components and free up more space, either for making smaller vehicles without losing interior volume, or adding space to a vehicle that wouldn't have had it otherwise. There's the additional benefit of reduced weight, something that EVs struggle with. Stellantis also claims improvements in efficiency, reliability, and cost, however, it didn't go into detail as to how this setup would do that exactly. We'll try to get in touch with representatives from Stellantis in order to get more information. We're still a ways out from seeing this technology in production Stellantis vehicles. The company said it aims to apply it to vehicles by the end of the decade. Saft is also looking at using it on stationary battery systems as well. So maybe we'll see it on a 2029 Ram 1500 REV, but for now, we'll be living with traditional chargers and inverters. Related Video: Green Alfa Romeo Chrysler Dodge Fiat RAM Technology Electric
