2015 Dodge Viper GTC available in 25 million no-cost combos with 1 Of 1 bespoke program

What's the one thing no car can have too much of? Here's a hint – it's not power. It's not efficiency, either, or technology, or even safety. It's exclusivity. It's one reason Rolls-Royce has become a legend building absolutely bespoke motor vehicles, and it's the reason Dodge, of all companies, is offering a new GTC trim level for its Viper supercar. Now, you might be asking what's so special and exclusive about a trim level? Well, in the Viper GTC's case, it gives owners access to a catalog of 8,000 shades of paint for the exterior, 24,000 "hand-painted" custom stripe patterns, 10 different wheel options, 16 interior trims and no fewer than six aerodynamic packages. That results in 25 million different configurations for the 645-horsepower snake. Most shockingly, the customization choices come at no additional cost on the GTC model. And it's only the start. Ordering a GTC will enroll customers in a unique VIP program called Viper Concierge, which according to Dodge, "offers an exclusive point of contact throughout the custom Viper build process." In other words, buyers will be given the means to stay right on top of their car's production, through the 140-to-160-hour painting process, which itself will be fully documented with pictures and through a mobile-friendly website, to the actual construction of their GTC. The Concierge process will start with the ordering stage, which will include Dodge sending customers a paint chip showing the owner's custom choosing, which they can confirm or refuse. Shortly thereafter, Dodge will send buyers a 1:18-scale "speed-form" replica in their chosen custom colors, once again to confirm or deny the build. Once the buyer's color and option selection is locked-in, that car becomes a one-of-one Viper for that year – no other buyer will be permitted to build a Viper to the same specifications. The concierge service also grants access to the Viper Ambassador Owner's Portal, where orderers can track their car's build process, receive weekly updates and share their excitement with (jealous) friends and family. And once the car is complete, it will be fitted with a custom dash plaque identifying its bespoke provenance – the owner can choose to have their name put on the badge, the car's nickname, or whatever they wish (Dodge will also ship each Viper with a second blank plate to include if the original owner sells the car).

Chrysler says its 8-speed transmissions will save 700 million gallons

Chrysler Group's TorqueFlite eight-speed transmission could be earning some serious green bragging rights if the company's projections are correct. The recently widely proliferated automatic gearbox, which is now in more than a million vehicles around the world, is poised to save drivers an estimated 700+ million gallons of fuel over the vehicles' lifetimes (an expected cost savings of $2.5 billion). In addition, Chrysler expects a reduction in CO2 emissions by more than six million metric tons. According to Chrysler, and depending on the vehicle, the TorqueFlite can improve fuel economy. The TorqueFlite autobox features particularly close ratios from fifth to eighth gear (see the press release below for the specific numbers), and uses low-viscosity fluid that doesn't need to be replaced. Transmission software adapts to the driving situation to optimize efficiency based on driver behavior, temperature, grade, stability control, and longitudinal and lateral acceleration. The TorqueFlite is capable of handling a variety of duties. As evidenced by the wide range of vehicles Chrysler Group has seen fit to equip with the eight-speed transmission, the TorqueFlite is capable of handling a variety of duties. Since its 2012 introduction, the TorqueFlite has gone from performing cog-swapping duties in Dodge Charger and Chrysler 300 models equipped with the 3.6-liter Pentastar V6 to changing gears in vehicles such as the Pentastar- and Hemi-powered Dodge Durango, Jeep Grand Cherokee and even the Ram 1500 EcoDiesel. For the 2015 model year, the eight-speed is finding its way into even more vehicles with the addition of a third version. In addition to the American-made TorqueFlite 845RE and 8HP70, the new 8HP90 will be manufactured in Saarbrucken, Germany. The 8HP90 is designed for higher torque loads, making it ideal for high-performance vehicles like the 2015 Dodge Challenger SRT Hellcat. The already-in-use 8HP70 will expand its duties to be used in 2015 Hemi models such as the Dodge Charger, Challenger, and Challenger SRT8. You can see the list of those benchmarks in Chrysler's press release below.

Hypermiling a Ram 1500 EcoDiesel to 38.1 mpg

You never quite know what Wayne Gerdes has up his sleeve. The man who coined the term hypermiling is always looking for adventurous ways to prove that anyone – even you... yes, you – can eke out more miles per gallon just by changing the way you drive. Saying that is easy. Proving it by going on outlandish cross-country drives is hard. But for Gerdes and his team of fuel economy fiends over at CleanMPG, hard is half the fun. Our latest adventure appeared, at first glance, to be nearly impossible. Which is why we always answer the phone when Gerdes calls. He likes to take journalists along on his drives, not only to try teach us how to hypermile but also to prove that we can be taught. The first time I 'helped' him and his team was when we got over 30 miles per gallon in a 2011 Ford F-150 XLT with the EcoBoost 3.5-liter V6. The EPA rated that truck with at just 16 mpg in the city and 22 on the highway. So, we'll count that trip as a success. Next up was a cross-country drive last fall in a trio of Audi TDI vehicles to prove that you don't need to drive extra slow to beat the EPA numbers. In fact, we made it from Los Angeles to New York City in just over 46 hours, cramped but not cranky. We had once again proven that how you drive is hugely important to your fuel usage. Our latest adventure appeared, at first glance, to be nearly impossible. The EPA says that the Ram 1500 EcoDiesel we would be driving gets just 22 combined mpg (19 city and 27 highway). Gerdes' idea was to drive it as far north from Houston, TX towards Detroit, MI as we could go on one tank. The day before we left, our itinerary got an extra stop. Instead of taking one of the official Shell Eco-marathon prototype vehicles to Detroit, it was decided to bring the winning diesel-powered prototype from the just-finished event to The Henry Ford Museum, where it had been arranged the car would be displayed. The winning car was built by a small team (just four students) from Sullivan High School in Sullivan, IN, who managed to beat a number of college teams with a score of 1,899.32 mpg. That target would be a bit out of reach for the Ram, but could we get 1,000 miles from the tank? Since the truck has a 26 gallon tank (officially, anyway), that would mean the EPA says we could only go 702 miles, assuming all highway driving. Could we make up 300 miles with careful driving? That spells both challenge and fun.
