The 2006 Lotus Elise and Exige feature a new seat design that saves weight, corrects posture and costs less than earlier designs. ProBax, a concept patented by a prostheticist, worked with Colin Chapman's wacky kids to come up with a seat that dispenses with lumbar mechanisms, thus lightening the seat. And you know how Lotus is about weight. You could call it automotive anorexia and you wouldn't be off the mark.
