Vectrix hybrid scooter for commuters: Coller than the Segway
Engineers at Vectrix Corp. are working on the industry's first hybrid fuel cell/electric-powered scooter, due out in approximately 3 years. An all-electric version will be introduced within the next 18 months. Parker Hannifin has partnered with the scooter maker to develop the direct methanol fuel cell, which will operate continuously at its rated power output until the battery pack is fully charged, then it will shut off. "A big advantage is that drivers won't have to rely on a charging infrastructure. All that's required is methanol and water—the same thing you have in your windshield washer fluid," says Craig Maxwell, VP of Innovation and Technology at Parker Hannifin. Engineers say the scooter's performance will be comparable to other vehicles powered by two-stroke, 250cc engines. Target acceleration is 0 to 50 kph in 4 seconds, as experienced by Maxwell's test ride on an early prototype: "Being a guy, I didn't want to hang on to the engineer driving the scooter, so I thought I'd just hang on to the scooter. When we started up, I nearly flew off the back end of the thing," he recalls. The scooter is targeted at the commuter market and will retail for $5,500.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
