Like a family crest, most Automotive emblems actually represent something important to their maker. Whether it be something historically important for the founder, ideals the brand strives towards, or a testament to someone’s ego, the symbol of each company has a history.
We stumbled across this encyclopedia of sorts that has cataloged the origins and meanings for almost every one of the worlds major automakers, and we must say, it’s pretty darn interesting. For instance Chevy’s logo has come about from…

Although we’ve already seen the NHTSA crash tests and the leaked IIHS test video, the official Insurance Institute for Highway Safety (IIHS) crash test results are finally in for the 2008 Smart ForTwo. And the little car did pretty well. IIHS awarded the micro machine its highest rating of “Good” for both front and side crash protection, and an “Acceptable” rating for seat and head restraint performance for rear-end crashes. So between this and yesterday’s Smart gangbang the little Smart is proving that yes, the ForTwo is a real car that won’t crumple like a tin can in crash. The full results and crash images are below.
FIRST INSTITUTE CRASH TESTS OF SMART FORTWO CAR: DIMINUTIVE TWO-SEATER EARNS TOP RATINGS FOR PROTECTING PEOPLE IN FRONT & SIDE CRASHESARLINGTON, VAThe Smart car is getting a lot of attention for its small size and style, and now it’s earning impressive crash test ratings. In recent Insurance Institute for Highway Safety tests, the 2008 Smart Fortwo, the smallest car for sale in the US market, earned the top rating of good for front and side crash protection. Its seat/head restraints earned the second highest rating of acceptable for protection against whiplash in rear impacts.
Smart Fortwo is classified a microcar, meaning it’s smaller even than minicars.Weighing about 1,800 pounds, the Smart is more than 3 feet shorter and almost 700 pounds lighter than a Mini Cooper.
It weighs about a third as much as one of the heaviest vehicles the Institute has tested, the BMW X5, a midsize SUV. As the price of fuel climbs and tougher federal fuel economy requirements kick in, auto companies are expected to introduce more small vehicles to the market. The Smart is the smallest car the Institute ever has tested.”The big question from consumers is, ‘How safe is it?’”, says Institute president Adrian Lund. “All things being equal in safety, bigger and heavier is always better. But among the smallest cars, the engineers of the Smart did their homework and designed a high level of safety into a very small package.”The Institute’s test results generally demonstrate how well vehicles stack up against others of similar size and weight. Frontal ratings can’t be compared
across weight classes, meaning a small car that earns a good rating isn’t safer than a large car that’s rated less than good.
“People base their buying decisions on a lot of factors,” Lund says. “If you drive only in congested urban areas where speeds are low, a small car may be more practical than a big one. We conduct crash tests so people who want small cars can choose the ones that afford the best protection.”The Smart has a crashworthy design for its size and is equipped with the latest safety gear, which is especially important in a small car. This vehicle’s standard
equipment includes seat-mounted combination side airbags designed to protect both the heads and chests of the driver and passenger. Also standard is electronic stability control (ESC), called electronic stability program in the Smart. ESC helps drivers maintain control during emergency maneuvers or on slippery roads. It engages automatically when it senses vehicle instability, and Institute research has found that ESC lowers the risk of fatal single-vehicle crashes by about half.
Restraints do more of the work in frontal crashes: The Smart mostly lacks a front-end crush zone, which is a key component in reducing injury risk in serious frontal crashes.Typically, front-end structures are designed to crush and absorb crash energy, allowing occupant compartments to slow more gradually, ideally with little or no intrusion into drivers’ survival space. Then a vehicle’s safety belts and airbags slow occupants further and are designed to spread crash forces more evenly across people’s bodies. The longer the front-end crush structure of a vehicle, the more gently occupants are slowed and thus protected from injury.
To compensate for the lack of front-end crush space, the Smart’s restraint system does more of the work of absorbing energy as occupants “ride down” a crash.
“We recorded a high head acceleration when the driver dummy’s head hit the steering wheel through the frontal airbag,” Lund explains. This indicates the test dummy used up all of the available ride down room in the Smart’s interior.
A stiff side structure and standard side airbags contributed to the Smart’s good rating in the side test, which replicates a crash with a pickup truck or SUV. Injury forces recorded on the driver dummy’s head, neck, torso, pelvis, and left leg all were low. However, the driver door unlatched during the crash. This confirms a finding of the National Highway Traffic Safety Administration’s side test of a Smart released last month. The Institute downgraded the Smart’s structural rating from good to acceptable, but the opening didn’t appear to affect dummy movement during the test, and injury measures on the driver dummy were low. Still, doors shouldn’t unlatch because in some crashes it could allow partial or complete occupant ejection, especially if an occupant is unbelted.
Small car safety: While small cars are safer now than before, so are large cars. In every category of passenger vehicle (car, SUV, or pickup truck), the risk of death is higher in crashes of smaller, lighter models. For vehicles 1-3 years old during 2006, minicars experienced 106 driver deaths per million registered vehicles compared with 69 driver deaths in large cars.
People often choose very light cars for fuel economy, but “you don’t have to buy the smallest, lightest car to get one that’s easy on fuel consumption,” Lund points out. “The Toyota Prius, for example, earns good front and side crash test ratings. It gets better fuel economy than a microcar, but it’s bigger and weighs more so we would expect it would be more protective in serious crashes.”
How the Smart was evaluated: The Institute’s frontal crashworthiness evaluation is based on results of a 40 mph frontal offset crash test. A vehicle’s overall evaluation is based on measurements of intrusion into the occupant compartment, injury measures recorded on a Hybrid III dummy in the driver seat, and analysis of slow-motion film
to assess how well the restraint system controlled dummy movement during the test.
The side evaluation is based on performance in a crash test in which the side of a vehicle is struck by a barrier moving at 31 mph. The barrier represents the front end of a pickup or SUV. Ratings reflect injury measures recorded on an instrumented SID-IIs dummy in the driver seat, assessment of head protection countermeasures, and the vehicle’s structural performance during the impact.
Rear crash protection is rated according to a two-step procedure. Starting points are measurements of head restraint geometry — the height of a restraint and its horizontal distance behind the back of the head of an average-size man. Seats with good or acceptable restraint geometry are tested dynamically using a dummy that measures forces on the neck. This test simulates a collision in which a stationary vehicle is struck in the rear at 20 mph. Seats without good or acceptable geometry are rated poor overall because they can’t be positioned to protect many people.
What really impressed me was watching the door window bulge with the front impact video, but NOT break. It really shows the strengths of the passenger cell.

AutoAlerts Reader Jonah has sent us this story of the ultimate expression of Smart ForTwo v. US North American roads. While the Smart ForTwo was peacefully sitting at an intersection, it got a bit of a surprise in the back end — a very large truck was interested in occupying the same space at the same time as his Smart ForTwo.
The Smart was hit from behind by a 5 ton delivery truck which served him like a tennis ball across the intersection to a cube van! Amazingly, the Smart ForTwo driver walked away with only minor abrasions from the airbags, and was quoted this morning as saying that he’s “just a little achy”.
Is a Smart Car safe? You can judge for yourself, but I think it faired pretty damn well seeing as the front windshield didn’t even break.
