The Tesla Model S' all-electric infrastructure is being credited with a heck of a lot more than top-notch energy efficiency. Because of the design, the vehicle lacks a large gasoline engine block up front, boosting the "crumple zone" and ultimately saving lives during an otherwise deadly crash. As a result, the sedan scored a combined record of 5.4 stars during a recent National Highway Traffic Safety Administration (NHTSA) test. That figure is higher than the maximum published rating of 5 stars, but Tesla received a more comprehensive report detailing actual results. The Model S also earned high marks with its rear-crash, side-pole-intrusion and rollover tests. Additionally, the lithium-ion battery did not catch fire at any time, and it never has in a Roadster or Model S -- the same can't be said for certain competitors.
