Hybrid engines aren't just for emasculating little sedans anymore. Nope, now they've found their way into big, manly vehicles such as 18-wheelers. The Kenworth T270 Class 6 hybrid-electric truck features the Paccar PS-6 diesel engine. It's got a motor/generator working with the transmission and a 340-volt battery to allow the truck to get help from electricity when traveling at speeds below 30MPH.

That improves fuel efficiency by 30 percent, which is nothing to scoff at when you're talking about cross-country drives. Here's hoping these things get on the road and start replacing standard trucks ASAP. –Adam Frucci
