Mercedes-Benz Has A Concept Car That Grows By Nearly 16 Inches

While it may or may not be the next-generation Mercedes-Benz CLS-class (note: probably not), the automaker took the wraps off a transforming concept car that grows in length significantly at highway speeds to better cut through air.

The Mercedes-Benz IAA concept (Intelligent Aerodynamic Automobile) was shown off Tuesday in Frankfurt and, according to the automaker, can grow by 390 millimeters to achieve a drag coefficient world record of 0.19. (The current generation Prius is around 0.25, for reference.)

The whole thing is powered by a hybrid powertrain that’ll never see the light of day and sports an interior array of electronics that’s probably something out of “Minority Report.” It’s the moveable aerodynamic elements on the IAA that could see production, and there are a lot of them.

In addition to the growing tail (Jalopnik has a gif, here) the IAA features other adaptive aero elements that help the car cut through the air. Flaps on the front and rear wheels grow by 25 millimeters and 20 millimeters respectively to cut down drag, and the front bumper’s louvres reach 60 millimeters underneath the car toward the rear to improve aero under the car. The five-spoke wheels also transform into discs at speeds over 50 mph, according to the automaker.

Mercedes-Benz showed off four other cars at its Frankfurt reveal including the new C-Class Coupe (including the already released AMG C-Class Coupe) an S-Class cabrio (and AMG variant) and its Smart Fortwo cabrio.

  • Buickman I like it!
  • JMII Hyundai Santa Cruz, which doesn't do "truck" things as well as the Maverick does.How so? I see this repeated often with no reference to exactly what it does better.As a Santa Cruz owner the only things the Mav does better is price on lower trims and fuel economy with the hybrid. The Mav's bed is a bit bigger but only when the SC has the roll-top bed cover, without this they are the same size. The Mav has an off road package and a towing package the SC lacks but these are just some parts differences. And even with the tow package the Hyundai is rated to tow 1,000lbs more then the Ford. The SC now has XRT trim that beefs up the looks if your into the off-roader vibe. As both vehicles are soft-roaders neither are rock crawling just because of some extra bits Ford tacked on.I'm still loving my SC (at 9k in mileage). I don't see any advantages to the Ford when you are looking at the medium to top end trims of both vehicles. If you want to save money and gas then the Ford becomes the right choice. You will get a cheaper interior but many are fine with this, especially if don't like the all touch controls on the SC. However this has been changed in the '25 models in which buttons and knobs have returned.
  • Analoggrotto I'd feel proper silly staring at an LCD pretending to be real gauges.
  • Gray gm should hang their wimpy logo on a strip mall next to Saul Goodman's office.
