The Elise didn't did not pass the low speed crash standards. That would be 2.5 MPH bumper standards. There is a limit on the cost of repair or no damage to other parts of the body besides the bumper. No bumber, no pass.
It did meet the other crash standards. I think the other is a 30 mph frontal crash into a barrier.
Actually, the Elise has always passed the crash standards - it was just not certified (an expensive process) - with the exception of the air bags.
The Federal Elise passes all crash standards including the air bags - it's supposed to be one of the very few cars to have actually been able to drive away from the "big" crash test.
The Elise has a waiver for the requirement of the 2.5 MPH bumpers (not 5 MPH - the limit was lowered many, many years ago). This requirement is not a "safety" standard as it has nothing to do with protecting the occupants of the car - it was simply a standard pushed for by the insurance companies to reduce their costs in the case of minor "bumps". It actually back-fired on the insurance industry, because, although it reduces the cost for minor bumps, it greatly increases the costs for anything bigger. The net result was that the 5 MPH bumpers (later reduced to the current 2.5 MPH) standard caused an overall increase in insurance costs.
From what I understand, the VX would fail US crash tests. After reading opinions offered by the forum and the age of the information I obtained, It would seem that the VX would pass the same crash tests that the Fed Elise does, but the manufacturer of the car would be recorded as GM.
GM are too large an entity to be granted waivers like lotus did (small vol independent manufacturer under economic adversity)
