Car Review of the year 2009

Car Review of the year 2009
To start the year with a bang, we need a test really special ... Volkswagen and provides an important new model in the form of the MKVI golf. It's not every day a new version of the famous VW presents the machine, especially a group to a predecessor, or to replace the amount.

To determine whether the newcomer is really a wonderful new year, we have a tough test in two days of marathon-mounted, which could take him under the spotlight in a studio before three competitors on the road trip right in the Advanced Test the heart of deepest Wales. It was one of the most memorable shoot-out in 2009.

As if that were not enough, we had tied in a special supplement in 1047, the number of received views of six generations of the Golf GTI, the tail of each generation hot hatch legend for the first time - even the model MKVI.

With so much going on, in January proved to be one of the busiest months of the year. Then it was seen our Living Legends function which remakes of modern classics, has to end up with cars that inspired its design.

With the help of several owners, we have seen in bringing together a unique group, to see if the nostalgia really belong in the design of today.

January was a quick glance, and the pace for the year 2009 years Auto Express road tests.

Mercedes-Benz B-class F-Cell Car 2011 Review

Mercedes-Benz B-class F-Cell Car 2011 Review
In May this year, the Mercedes-Benz B-Class F-Cell will be the fuel cell powered second car to be delivered to consumers (like the first Honda FCX Clarity). What you may not know that Mercedes-Benz was the first manufacturer to produce a vehicle to appeal. Dubbed NECAR (New Electric Car), began in 1994 and was a single-seater van. The fuel cell, battery, the electric drive unit and related facilities were all inside, making it impossible for the truck to the consumer, or almost anything other than research and marketing.

Until 1999, Mercedes-Benz has reduced the size of the system completely enough to fit into the sandwich floor of Class A architecture. This version does not allow the production, but to go in 2004, 10 residents of Berlin were fuel cell A-classes. These vehicles have been the direct precursor of the B-Class in 2011 appears here.

Did You Sleep Through Science class?

Class B is on the A-class architecture is founded. Design sandwich (an empty hollow in the floor of the cabin which, among other things, the funnel of the engine under the passenger in frontal crash) makes it an ideal candidate for the propulsion replacement for it provides a place to put a little technology. The Class B actually the same size, its gas and diesel brethren. The only difference is noticeable in the absence of a plateau of goods moving, the tray is locked in the higher (normal to the untrained eye) position, to accommodate the battery.

What makes this B-Class F-Cell "is a zero-emission cars is the fuel cell polymer electrolyte membrane. Yes, that's a mouthful. The explanation is simple: the fuel cell at high pressure d 'hydrogen (H2) and oxygen (O2, collected in air is converted into electrical energy) and water (H2O). It is a chemistry of fancy, but it boils down to is electrolysis Vice versa. If you remember, science junior high, when an electric current to H20 was introduced, the result is to produce O2 and H2. For the fuel cell with an energy and H2O, H2 is a membrane that allows protons H2 fed to happen, but not electrons H2. Protons with O2 on the other side of the membrane added H20 and H2, the remaining electrons (if the poles are designed to produce) electricity, therefore electric motor vehicle. Got it? Otherwise, remember that it is simply the reverse of electrolysis, and be a conversation with someone to survive, liberal-arts ".
