Citaro Hybrid Buses Deployed In Germany

Daimler’s push towards greener technology is not limited to cars, as manifested by the fleet deployment of electric Sprinter vans in Spain and now with hybrid buses in their home country. Named the Citaro G BlueTec Hybrid, two of these buses will be deployed in Bremen as demonstration units on how a route can be covered by an alternative fueled mass transport vehicle.

These hybrid buses are the result of years of development by the German carmaker, which is a testament to the forward-thinking values of the company in the development and implementation of hybrid vehicles for the general public. With an output of up to 240 kW, the Citaro Hybrid buses use one of the world’s largest lithium-ion batteries, which power four electric wheel hub motors. The current battery pack weighs 350 kilos, compared to the first 3-ton batteries utilized for experimental hybrid buses three decades ago.

Regenerative braking and a small auxiliary diesel provide additional power for the electric bus’ considerable energy needs. Notably, the auxiliary diesel unit is only half the size of typical diesel engines for buses, weighing in at 450 kg but developing 214 hp from its 4.8 liters.

U.S. Leg Of F-Cell World Drive Reveals Poor Infrastructure

hydrogenpump U.S. Leg Of F Cell World Drive Reveals Poor Infrastructure

While the popularity electric vehicles has spurred the installation of charging stations to feed these EVs, manufacturers like Daimler feel the inadequate infrastructure support that the government and private sector are giving to alternative fuels like hydrogen.

As the F-Cell World Drive planners have anticipated, there are very few hydrogen refueling stations across the continental U.S. and in the 35 refueling stops that the F-Cell cars will make in the U.S. leg, only one stop can be made at a public refueling station. The rest of the fillups will be from Linde tanker trucks strategically positioned along the route.

Despite the favorable impressions and acceptance garnered from the public about the hydrogen-powered vehicles participating in the World Drive, Mercedes has seen that the short-term viability in the U.S. of the F-Cell cars is doubtful, due to the lack of infrastructure. According to Thomas Weber, Daimler member of the board for Group Research and Development, “The American market is already active in the field of fuel cell technology, but like in Europe, there is still a need for development when it comes to infrastructure. Together with our regional partners, we want to point out the potentials of this technology and to get important lead markets ready for the rollout of a high number of electric vehicles with fuel cell technology.”

F-Cell World Tour Reaches The Continental U.S.

In January, Mercedes kicked off a world event in the form of its Mercedes Benz F-Cell World Drive. As planned, 3 B-Class vehicles running on hydrogen arrived in the U.S. this week, and the trio will continue their journey across the continent starting from Fort Lauderdale on the East Coast.

If everything goes as planned, the vehicles will cover 7,500 kilometers by March 18, having reached Seattle by then. Fueling partner Linde will provide the unique hydrogen fuel these B-Class cars need. These electric hybrids are powered by a 136 hp electric motor and have a range of 250 miles before the hydrogen fuel needs to be refilled.

The next leg will be across Australia. Before the U.S. leg, the F-Cell vehicles covered the European countries, accumulating 3,600 kilometers in the process. Says Thomas Weber, member of the Daimler Board for Research and Development, “We will have reached market maturity with fuel cell technology by 2015 at the latest. From that point we would then be in a position to bring several 100,000 vehicles, in a variety of different model series, onto the roads.”

Renntech and Mercedes Refresh Pikes Peak GLK350

Premier Mercedes-Benz tuner has once again put its radical GLK350 Pikes Peak Rally Car on the road. Initially redisplayed at the Pittsburgh International Auto show two weeks ago, the radical GLK will next stop at Milwaukee, then on to Cincinnati, Cleveland, Kansas City, Minneapolis and Denver. Final stop will be at the Mercedes-Benz Classic Vehicle Museum in Irvine, California.

In its initial appearance in 2008, this GLK had a hybrid powertrain consisting of a 72-volt electric motor providing an additional 26kW to the SUV’s 3.5L V6 engine. There is no indication of a drivetrain upgrade but Renntech and 3M’s Commercial Graphics Division cooperated in refurbishing the GLK with 3M’s 1080 Scotchprint textured automotive vinyl wrap. Preprinted 3.5 mm dual cast film was applied to all exterior surfaces, mixing a carbon fiber and brushed steel appearance. Red striping adds a touch of color to the otherwise matte surface finish.

Says a Renntech press release, “This original body kit was entirely designed and engineered by RENNtech in-house, using the latest in Computational Fluid Dynamics (CFD) software and rapid prototype capabilities. The concept behind the restyling was to not only completely change the vehicles appearance, but utilize vinyl materials in finishes rarely seen in the automotive world.”

Fuel Celled Cars To See Rapid Price Declines By 2015

Achieving a $50,000 price point for a fuel-celled sedan by 2015 is going to be difficult but doable. This was the statement given to Automotive News by Daimler’s e-drive and future mobility chief Herbert Kohler. With Toyota declaring its intention to launch a fuel-celled vehicle at such a price point in four years, Mercedes, a strong proponent of fuel-celled vehicles has no choice but to match this declaration. Kohler admits that “ By 2015, we think a fuel cell car will not cost more than a four-cylinder diesel hybrid that meets the Euro 6 emissions standard. By 2013-2014, we want to bring a four-digit-number of fuel cell vehicles to market”.

Mercedes-Benz is also contemplating the development of fuel cell versions of the A-, C- and E-Class lines in the next five years. Costs would rapidly decline if Mercedes can incorporate its fuel cell technology into several models and hit mass production levels.

Kohler added that fuel celled vehicles can be expected to be cheaper than battery-powered cars of the same size in the next five years. He also said that the second-generation fuel cell cars would use less expensive hardware when they are introduced in 2013. The Mercedes-Benz B-Class F-Cell is currently available for lease to selected customers in the U.S. for $849 a month.
