BMW hydrogen car offers near-zero emissions luxury

A snazzy new 7-series BMW currently on tour in Canada has a water bottle sitting by its exhaust pipe -- one labelled "exhaust."
Liquid hydrogen powers this Beamer, which showed up in Montreal's old port on Tuesday as part of a tour.
"There (are) almost no emissions," BMW's Jochen Frey told reporters.
"And what happens is, if you drive in the city you actually clean
the air. Usually in (the) downtown of the city, the air is a little
more polluted."
But after going through the vehicle's emissions controls system, any
air released back to the atmosphere will be somewhat cleaner, Frey
said.
Auto expert George Iny of the Montréal-based Automotive Protection Association was impressed by the vehicle.
"We've been reading about it, so I'm very happy to see it in person.
It's brilliant from an engineering standpoint," he told CTV Montreal.
The vehicles were brought in Monday night from Trois Rivieres, and
will head to Toronto on Tuesday night. The cars are exclusive (the 7
series are the already the most luxurious model of BMW).
The 7 series cars normally go for about $175,000, but BMW say the hydrogen models are literally priceless.
"I think they are, at the moment, unpayable," Frey said. Fewer than
100 exist in the world, and have mostly been snapped up by celebrity
clients.
On its website, the BMW Group touts hydrogen-powered vehicles as a
way to fight the carbon emissions that drive global warming and climate
change.
Alternative fuels won't cut it in the long run, it said.
"Only hydrogen fuel -- won from renewable sources such as sun, wind,
water and biomass -- can provide a reduction in total CO2 emissions and
meet our energy needs in a sustainable way," BMW said.
BMW's vehicle is powered by a 6.0-litre, 12-cylinder hydrogen
combustion engine, with water being the only emission substance -- when
operated on hydrogen. The BMW engine can also operate on gasoline.
BMW said its vehicle can "seamlessly" use existing refueling
infrastructure. Refueling with hydrogen is "clean, easy and secure," it
said.
The car uses cryogenic liquid hydrogen technology, which BMW said is
more energy dense than other techniques such as compressed hydrogen
gas.
Iny said that the car is "way ahead" of being ready for the average
customer. Besides its cost, liquid hydrogen isn't exactly available at
the local gas station yet.
"This is not something you're gonna be driving home anytime soon," he said.
Here are some performance statistics about the vehicle:
- 191 kW / 260 hp
- 390 newton-metres / 290 ft-lb. at 4,300 rpm
- Zero to 100 kilometres per hour in 9.2 seconds
- Top speed: 143 miles per hour / 230 kilometres per hour (electronically governed)
- Total range: 435 miles / 700 km
- In hydrogen mode: 125 miles / 200 kilometres
- In gasoline mode: More than 300 miles / 500 kilometres
