Volvo hybrid concept: If only lithium were reality

Lithium powered hybrids rock, but they are not yet ready for primetime

Wow! Seriously, could the Frankfort Auto Show become any more focused on green issues, at least in terms of concepts? It's hybrid cars galore - in addition to clean diesel and biofueles. Unfortunately, so many of the concepts, such as the Volvo Recharge Hybrid, are dependent upon technologies that are just not ready for reality.

Imagine 62 mpg on electric power only. That's what the Recharge hybrid promises.

Starting to sound like GM's Chevy Volt?

InsideLine notes that the 4 electric motors in each wheel combined with 1.6 liter flex-fuel engine could achieve a whopping 120+ mpg for trips less than 90 miles. In trips over 100 mpg, the Volvo hybrid would eventually average out at 45 mpg.

Still, much like the Volt, the Volvo hybrid can meet most commuter's daily needs with just electric power. Unfortunately, just as with the Volt or other plug-in hybrids, the technology is completely dependent upon lithium-ion batteries.

Ultimately, it is isn't automakers which control the future, its energy storage/providers - whether lithium, ultracapacitors, or hydrogen.
