6 hypermiling cars that get over 100 miles per gallon
By Cat DiStasioFuel efficiency is one rating that can really set a car apart from the pack. Although you can't yet walk into just any dealership and drive away in a vehicle that gets more than 100 miles a gallon, there are some sweet rides out there that demonstrate just how incredibly efficient a car can be. To get a better idea of what the uber-efficient car of tomorrow looks like, we've compiled some of the most efficient vehicles on the planet, all of which exceed that 100-mpg marker. In fact, most of the cars featured here leave that rating in the dust, and several break into the quadruple digits.
Volkswagen develops augmented reality service manual for the XL1
After developing an augmented reality car manual for the Audi A3 and similar software for wearables like Glass, Metaio certainly knows a thing or two about the AR space. It's no surprise then, that Volkswagen has collaborated with Metaio to develop an augmented reality iPad app for the 2014 XL1 hybrid diesel that debuted earlier this year. Called MARTA (Mobile Augmented Reality Technical Assistance), the app uses the iPad's camera to view the internals of the vehicle and label the various parts and elements so that VW service workers will know what they're working on. MARTA also shows step-by-step instructions on how to repair and replace certain components, right down to which direction mechanics should be facing. You can even use the app to test out different design elements like a new hood or a different color. And just in case all that AR doesn't prove to be useful, the app provides a good ol' fashioned text service manual as well. Seeing as the MARTA is an AR app for a very limited edition vehicle, we don't expect it to be of much use outside of certain VW specialty shops. Still, it's yet another sign that incorporating augmented reality into digital car manuals just makes sense.
VW confirms it will build hyper-efficient XL1, Autocar gets to drive one
Think the Volkswagen XL1 concept is too far out there to ever get built? Tell that to the blokes in Wolfsburg. German source Automobilewoche is reporting that executives Ferdinand Piech and Martin Winterkorn both confirmed that the car will be produced in small numbers, first for Germany and later coming to the US and China. It's powered by a diesel engine with less than one liter of displacement, managing 313mpg combined (that's Imperial, 260mpg using American units) putting out just 48hp and thankfully assisted by a 27hp electric motor. Not much, but enough for the 1,750lb car, which Autocar correspondent Milton Holloway got to drive and said feels "fully sorted" despite an engine that's a bit rattly. It is a diesel, after all.
Volkswagen's XL1 concept plug-in diesel hybrid has 260MPG fuel efficiency, questionable aesthetics
Steaming down the autobahn could be about to get a whole lot more efficient. Volkswagen has carted out its newly updated Super Efficient Vehicle concept, now dubbed the XL1, which -- after a great deal of fuzzy math, we're sure -- is rated at a 313MPG fuel efficiency and produces only 24g of CO2 per kilometer traveled. There's an electric motor and a TDI diesel engine making all the buzzing and roaring noises inside, while the overall body design is focused on making the car as light and as aerodynamic as possible. Volkswagen has achieved a 795kg curb weight by using carbon fiber, magnesium, ceramics, and aluminum to shave down any excess portliness from the XL1, while wind-tunnel testing and optimizations have resulted in a rather exemplary 0.186 drag coefficient. It's rare to see such attributes on anything outside the supercar realm, but then there's a reason why this PHEV is still only a concept. FOF. Update: Oh bother. Turns out Volkswagen's mileage claim is based on Imperial gallons, which are 1.2 times the size of the American stuff, meaning that the XL1 actually measures in at 260MPG when viewed through US glasses. Now do you see why the rest of the world has gone metric?
