Smart is just getting ready to launch its new Fortwo and Forfour minicars, riding on a completely different platform, and the diminutive brand wants to show that its latest creations can stand up to some serious abuse. For such a tiny car, the crashworthiness of the Smarts is a legitimate concern when taking on larger, heavier vehicles. To prove their survivability, the company filmed a head-on collision pitting the latest Fortwo against a Mercedes-Benz S-Class weighing more than twice as much.

When it unveiled the latest cars, Smart touted that it crash-tested them against the larger Mercedes-Benz C-Class and S-Class. Among their updates, the Fortwo and Forfour use a substructure containing ultra-high strength, hot-formed steel and maximum-strength, multiphase steel. They also have larger crumple zones.

Of course, Smart can make all the claims that it wants about the cars' safety, but actually showing it to people is much more convincing. At 5,088 pounds, the S-Class dominates the 2,478-pound Fortwo in terms of weight. Scroll down to see how the little hatchback fares against the more expensive, luxury sedan in a 31-mile-per-hour frontal crash.

      The smart fortwo isn't 2400lbs. It's 1600lbs. Even the much heavier smart ev is only 2000lbs. The 2400lb number is maximum vehicle weight... That's the amount the vehicle is designed to carry including passengers. The new smart redesign is almost identical in weight to the current model according to smart. The idea of the tridion cell isn't too make you invincible... It's to prevent intrusion into the passenger cabin. It does this perfectly almost every time. The cell will have no ability to slow your decent safely to prevent internal injuries. It didn't claim to. This is a true fact of any vehicle involved in a collision. If you look at the numbers though the smart has the fewest numbers of casualties per units sold and millions of miles driven. This is not open for debate. The numbers don't lie.

      I guess no one here rode bikes, scooters or skateboards when they were kids, aka didnt have fun. Well the Smart is a toy just like a scooter or bike, but practical and way more fun. I don't want a generic basic boring car like every car i see on the road every. I stand out on the road in my clean matte grey smart and have a better driving experience than everyone driving non sports cars. And i have friends that have sports car and smarts so anyone's opinion is literally invalid. But keep talking mindless about how YOU know its not safe because you are so smart right?!! And know the car way more than me or an actual owner right??! ROFL, absolutely hilarious, humans.... one odd bunch that i happen to be apart of, i dont understand most of them...

      how often do you crash at just 31 mph? Show us the 45 mph crash.

        Because their natural habitat is the city, and 31 (50kph) is the speed it will be travelling in. I'll be interested to see how they get on in the Euro Ncap ratings though

        It's a frontal collision. The average person would have at least a few moments to slam on their brakes and reduce their speed a bit before impact.

      When IIHS did this same test they said the G forces exerted on the occupants of the Smart were enough to be life threatening. Safe is a relative term because the energy in an impact is based on the equation E=1/2*m*v^2 Velocity (v) is the driving factor but in an impact like this the mass (m) has a significant impact as the merc outweighs the smart by more than double. Rough calcs of the energys involved and the smart would have been moving 21 kph backwards after the accident. (ignoring impact absorption of energy) In short, the smart feels a ~70kph impact (44 mph) and not the 50kph (31mph) they point to in the video. That works out to about 32 Gs in the merc and about 65 Gs in the Smart. 50 Gs is considered the survivability limit in this near perfect short term impact situation.

        Translation for the layman: The chassis cage is too rigid, and the short hood section doesn't allow enough crumple zone to safely absorb enough energy to mitigate the amount of energy from larger, heavier vehicles. This would be great if 90% of the cars on the road were Scion iQs, Minis, Fits, and so on. But in the real world of gas-whoring SUVs, these Smart cars aren't a smart purchase for any reason, especially when you can land a Honda Fit for less, with more cargo space, passenger space, and better impact safety.

      They didn't show what happened inside. They didn't show in slow motion as the IIHS videos do. Fail!

      2478lbs? That is just ridiculously heavy for a 2 seat econocar. The Mitsubishi Mirage, with 2 more doors & seats, is barely 2000lb.s

        It doesn't even come close to weighing that. That's the maximum weight!

        Crash the Mirage into an S-class and see what happens.

      The reason Smart cars are so safe is because they're based on Mercedes monocoque F1 cars. A monocoque is extremely safe, it's basically a steel bubble that inpenetrable because of it's small size. The fact it's small is ironically why it's so safe.

        The reason is, renault make some of the safest small cars, that is proven by history.

        "based on Mercedes monocoque F1 cars" is total BS. Another fact is the new Smart doesn't even have the so called Trideon cell.

The amount of G-Force you experience from the sudden stop will kill you because your brain will squash against the front of your skull.

      I love how we don't see the side of the car that hits the S-Class. Totally misleading.

      Why would anyone buy a smart over a Fiat 500?

      Looks like Mercedes is trying to write its own law of physics.

      I love how they switch from the birds eye view to avoid showing how the dash on the stupid car moves forward into the cabin and potentially crushes any unfortunate soul that would be sitting there. Wow, it's so safe!

      2500 lbs for a car that small? My Ford Focus ZX3 that could very comfortably seat four adults and a child with a 2.0 liter engine weighed 2500lbs. Gdamn are cars getting heavy!

        That's exactly what I thought when I read that figure.... 2478 lbs on this tiny little thing?!?
