The video above is an interview about the BMW Hydrogen 7. There are some BOLD claims in this video. The "shell" can keep "soup" hot for months and an "ice man" cold for "17 years." You also get a look at the "H2 button" in the test drive of the Hydrogen 7. Two more videos are below the flow. The first includes a look at a special light and exhaust cover on the back of the hybrid BMW X6 that will tell the public when you are in EV mode. The third video is all about the F 700 hybrid BMW Mercedes Benz.

Mercedes announced about a month ago that they would be showing off their new DiesOtto engine in a new concept car at the Frankfurt Motor Show. As a refresher, the DiesOtto (Diesel + Otto cycles) is an HCCI/spark ignition combination engine. It's basically the same as the GM HCCI prototype we drove in an Opel Vectra and Saturn Aura recently. The 1.8L four cylinder engine has an output of 238hp and 295ft-lb and is rated at 44.4 mpg (US) in the F700.

The F700 that contains this very efficient new engine is a full size luxury sedan of which we have our first tease in the photo above. From what can be seen in the photo it looks like the F700 has a long hood/short rear deck profile, an odd choice for a car with such a small engine. Regardless we'll probably see elements of this design in future Mercedes models, perhaps the new E-Class next year?

Mercedes is bringing the green to the upcoming Frankfurt Motor Show with their new sedan concept car, the F700. Remember that DiesOtto engine that we told you about a while back? It's making its debut in this new luxury sedan. To refresh your memory, that engine produces 238hp and 295ft-lb. of torque from just 1.8 liters of displacement using some new technology known to many as homogeneous charge compression ignition, or HCCI, which "operates in compression ignition mode under light loads and spark ignition at other times" according to our own Sam Abuelsamid. The fuel mileage of the car with the DiesOtto engine is expected to be almost 40 miles per gallon, which is excellent for such a large vehicle.

The new F700 concept is just one of 18 vehicles that Mercedes is expected to showcase, including new Bluetec diesels and hybrids with both gasoline and diesel engines.
