2016 BMW Hydrogen 7 Review
2016 BMW Hydrogen 7 Review
2016 BMW Hydrogen 7 Review - Theres a new method with regard to fueling cars. Instead of the usual dispenser nozzle, a plastic hose about how big a sewage pipe is that come with the vehicle. An automatic clasp closes automatically about the tank opening. The airtight hose system was made by Germanys Linde conglomerate and had been installed at several German filling stations. Its designed to allow the person to fill her or his car with liquid hydrogen in only eight minutes. Berlin is just about the few places that already gets rid of such a filling station. Last few days, German car-maker BMW utilized the facility to present car testers while using the first small series vehicle on the planet that drives upon both gas and also liquid hydrogen. This "Hydrogen 7, " will participate BMWs upscale "7" compilation of vehicles, and BMW is now carefully preparing for making the new car open to customers.
2016 BMW Hydrogen 7 Review
Starting inside March, the car will probably be delivered to concerning 100 celebrities, but thus far BMW is retaining mum about his or her names or exactly what their leasing rates may very well be. The cars builders are hoping to achieve insight into your practical reliability of your technology many find the be all and end every one of the car industrys ecologically fresh and climate warm and friendly future.
The Munich-based organization is promising "sustainable mobility and sheer joy of driving, inch citing the cars 260 hp, 12-cylinder engine. The Hydrogen 7s standard combustion engine has become adapted to are powered by both liquid hydrogen and also regular gasoline also -- and numerous it. The company says the vehicle will consume typically 13. 9 liters (3. 7 gallons) each 100 kilometers (roughly 19 miles per gallon) utilizing regular gasoline along with a whopping 50 liters to drive the same distance when fuelled by hydrogen.
In different words, BMW has developed an energy-guzzling serps that only looks like its environmentally friendly -- some sort of farcical ecomobile whoever only true merit is that involving illustrating the cardinal dilemma of your possible hydrogen-based economy.
The problem is actually that hydrogen is at scarce supply and producing it requires vast amounts of energy. Climate-friendly production involving liquid hydrogen over a large scale presupposes some sort of virtually unlimited supply of ecologically produced electricity -- not something gonna materialize in the future. Thats why energy experts from the Wuppertal Institute with regard to Climate, Environment and Electricity believe forcing the transition to a hydrogen-based economy over the following three to four decades is "not a good ecologically sound" idea.
Storing the volatile energy source also requires vitality and money. In order to that promises a fair storage life is actually liquid storage with temperatures below -253 diplomas Celsius (-423 diplomas Fahrenheit). The technique of cooling the storage facility down to such a reduced temperature alone burns up to one-third with the energy contained available as one fuel tank.
Volatile fuel
BMWs thermo-tank, specially designed to hold on to liquid hydrogen as well as regular gasoline, gets the same diameter since the drum of a washing machine. It has a number of 170 liters (45 gallons) and occupies half the start. But it can certainly only hold ten kilograms (17. 6 lbs) with the extremely light hydrogen energy resource -- barely enough for any 200 kilometer (124 mile) vacation. Whats more, a few of the tanks contents need to be released as they get hot and evaporate -- even the top insulation system cannot keep temperatures lower forever. After nine days, half the tank load is now bad.
BMWs competitors are generally somewhat puzzled through the companys decision for you to adapt combustion machines -- known because of their high fuel consumption -- in order that they will run over a fuel as hypersensitive and problematic since liquid hydrogen. "We believe its non-sense, inch says Frank Seyfried, research director for hydrogen-based propulsion with Volkswagen.
With your exception of BMW, every car company around is betting over a different technology: energy resource cells, which transform hydrogen into electricity by way of a chemical process. The electricity generated in the act then drives the vehicle. This method promises much larger efficiency, but the actual technology yields merely modest driving functionality. Test cars with fuel cell machines can produce among 50 and ninety days kilowatts, but they consume just about 14 liters involving hydrogen per 100 kms (62 miles) -- some sort of fuel value corresponding fot it of four liters (one gallon) involving gasoline.
BMWs chief programmer Klaus Draeger nonetheless thinks theres justification not to shelve your combustion engine. "Its the merely engine that matches our requirements regarding dynamics, " he or she explains.
And so, in creating your Hydrogen 7, BMW is announcing an upcoming of putatively fresh, full-throttle driving. The brand new car caters for the pleasing fantasy involving customers spoiled by high-horsepower engines: They can conform to environmentally friendly standards without creating any sacrifices, burning "clean" fuel to their hearts content. Advertizing images screen the Hydrogen 7 in opposition to a backdrop of wind turbines and solar panels.
But the image is one of deceit. Because the hydrogen dispensed for the new filling stop is generated mainly from petroleum and natural gas, the new vehicle puts about just as much strain on the environment as a heavy truck which has a diesel engine. Add the losing of environmental benefits involved in the production and transportation with the putatively clean fuel to the intake of the car itself therefore you get an precise consumption corresponding to far more than 20 liters (5. 3 gallons) involving fossil fuel.
The earth isnt the merely loser: Customers will also have to shell out big money for their misleading display of ecologically responsible driving. The recent standard price with regard to liquid hydrogen is actually 57 euro cents (0. 73 ALL OF US cents) per liter (0. 3 gallons). And the price tag on a 100 kilometer (62 mile) drive within the Hydrogen 7, in a comfortable speed, is all about €30 ($38).
BMWs hydrogen energy unit vehicles will start testing within a brief period of time - yet progresses in battery innovation may imply that they never achieve creation, as indicated by the companys deals and promoting manager Ian Robertson.
The firm has long ago run a trial with hydrogen-fueled vehicles; beginning in 2007 it put 100 6.9-liter V12-engined 7-Series out and about equipped for running on petrol or hydrogen. Creating 256bhp and 290lb ft, the autos hit 62mph in 9.5secs.
The new era of test autos are as of now a work in progress, with the engineering being co-created with Toyota. Specifically, bundling of the power module stack and hydrogen stockpiling are said to have progressed altogether as of late.
"Weve said well keep on putting resources into hydrogen and that will bring about a little number of creation test vehicles being made to demonstrate engineering works," said Robertson. "The main problems lie not around what we can do, however, yet whether the framework can be developed to supply hydrogen in the commercial center expense viably."
As an aftereffect of the issues of the expense of hydrogen creation and circulation, Robertson recommended battery innovation increases could rather quicken offers of electric vehicles. Progresses in lithium particle innovation are situated to be trailed by a change to lithium air and afterward strong state batteries. These advances through the following ten years could "see charging time and reach stresses vanish" as per Robertson.
Likewise, Robertson demonstrated that he could now imagine a period later on when interest in inner burning motor engineering changed to battery and electric engine progresses. "Sooner or later the innovations will switch over," he said. "At the point when the hybrid comes and the center gets to be power, the rate of learning will quicken considerably quicker," he said.
BMW is hoping to offer 15,000 i3 electric or extent expanded vehicles in 2014, making it the third biggest electric auto creator. The i3 will go on special in Asia in 2015.
BMWs long haul hydrogen arrangements are comprehended to base on a future model for its "i" scope of autos. The mooted BMW i5 would utilize an amended variant of the powertrain utilized as a part of the Toyota FCV.

2014 Volkswagen Golf 7 Variant
- Versatile station wagon is significantly roomier than predecessor, yet up to 232 pounds lighter
- TDI® BlueMotion model is the most fuel-efficient Volkswagen wagon ever, with an EC combined fuel consumption figure of 71.3 mpg
- Golf Variant goes on sale in Europe in August, 2013
Volkswagen will expand the Golf range even further at the 83rd Geneva Salon de lAutomobile with the debut of the new Golf Variant (wagon). Like the new Golf hatchback, the Variant is significantly lighter than its predecessor, to the tune of up to 232 pounds.
For the first time, Volkswagen is also offering the Golf Variant as a stand-alone and extremely fuel-efficient TDI BlueMotion model in Europe. The 110-horsepower Variant is the most fuel-efficient Volkswagen wagon ever, with an EC combined fuel economy figure of 71.3 mpg (equivalent to 87 g/km CO2) when equipped with the six-speed manual transmission.
The all-wheel-drive Golf Variant 4Motion will also debut in Geneva. It will be available as a TDI Clean Diesel model with 105- and 150-hp engines. Volkswagen has a Golf Estate TGI BlueMotion with natural gas drive (CNG) in the pipeline, too.
Roomier than ever. More than 1.8 million Golf Variants have been sold since this practical wagon was launched 20 years ago. The new Golf Variant is a sporty and elegant all-rounder that combines great gas mileage and excellent performance with premium quality and versatility.
The versatility has been improved even further in the new model because the trunk volume with the seats in place has been expanded by 20 percent; with the rear seats folded, the load area isincreased by nearly nine percent.
The cargo area is now 41.5 inches long; with the rear seats folded, the length is 72.1 inches; and the load sill is just 24.8 inches high. Thus, the Golf Variant is up to the majority of hauling tasks. For the first time, the wagon features a roller blind with a two-step roll-up mechanism to cover the luggage compartment: when its not needed, the blind and the compartments net partition can bestowed under the cargo floor.
In addition, the cargo floor is adjustable for height and can be locked in different positions. The split rear folding seat has also been completely redesigned and is more practical and easier to use, while there are now four bag hooks in the trunk area.
Even more striking. The Golf Variant is 12.1 inches longer than the hatchback, at 179.6 inches overall. Up to the B-post, the Variant is the same as the hatchback, but is unique aft of that point. It retains the precise and timeless lines that mark out the new Golf, but it is obvious that the car was designed in parallel with the hatchback and not simply derived from it.
Thats why the silhouette of the new Golf Variant is particularly distinctive, although there is one common design theme at the back of the car: The designers succeeded in transferring the classic Golf C-pillar shape, which is like a drawn bow, to the D-pillar of the Variant. Visually, the "third" side window forms a part of the D-pillar.
In contrast to the Golf hatchback, the so-called character line is picked up again behind the rear wheelarches and carried over completely to the rear of the vehicle, lending an even more muscular appearance. The precise window sill, the long side window, and the slightly rearward-sloping roof underscore this dynamic look. In addition, the new Golfs revised proportions - short body overhangs and a wheelbase that is increased from 101.5 to 103.8 inches - further enhance the sportiness.
Typically Golf. The new two-part taillights on the Golf Variant emphasize its family resemblance to the rest of the Golf range and reflect Volkswagens Brand DNA. The half of the taillight thats integrated in the trunk lid, however, is bigger than in the hatchback version and forms a longer parallel line with the graphic on the lower part of the trunk lid. In addition, a clear-cut difference between the Golf Variant and the "classic" Golf exists in the design of the middle part of the trunk lid and the bumpers: Whereas the license plate of the hatchback model is in the bumper, the designers of the Golf Estate decided to integrate it with the trunk lid.
TDI BlueMotion goes its own way. In Germany, the Golf Variant will be available in the Trendline, Comfortline, and Highline equipment lines, but the TDI BlueMotion model will only be offered in Trendline and Comfortline trims.
The TDI BlueMotion is not only different from the other models in the range from a technical standpoint, but also visually. From the front, the most fuel-efficient Variant can be distinguished by a partially closed radiator grille shutter, while flaps on the rear window rim identify it from the back. In addition, the model is equipped with an optimized underbody and wheelwell paneling, a 0.6-inch lower ride height, and super-low rolling resistance tires. There are also TDI BlueMotion badges on the front, back, and side of the body, as well as an optional "Clearwater Blue metallic" color.
High tech, high safety. Like all new Golfs, the Variant is equipped with a Stop/Start system and battery regeneration mode. For the first time on a wagon, it also has the new Automatic Post-Collision Braking System, which automatically slows down the vehicle when it is involved in an accident in order to further reduce its residual kinetic energy. Standard features on the European model include:
- seven airbags
- electrically adjustable door mirrors
- outside temperature display
- chrome rings around the interior vents
- eco-HMI (fuel consumption-related information on the multi-function display / instruments)
- electronic stability control (ESC)
- height-adjustable drivers seat
- power windows front and rear
- air conditioning
- steering column with height and length adjustment
- center console with storage compartment
- electronic parking brake with auto-hold function
- XDS differential lock
- tire pressure monitoring indicator
- asymmetrically split and folding rear seat backrests, with remote unlocking
- electro-mechanical power steering
- dust and pollen filter
- daytime running lights
- touchscreen with 5-inch TFT display
- central locking with wireless remote control
Premium class features. As a new feature, the PreCrash preventive occupant protection system is available for the new Golf Variant. If this system detects a potential accident situation, the drivers and front passengers seatbelts are automatically pre-tensioned to ensure the best possible protection by the airbag and belt system. When an even more critical situation is on hand, such as severe oversteer or understeer with ESC intervention, the side windows are closed (except for a small gap), along with the sunroof. When the windows and roof are nearly closed, the head and side airbags offer optimal energy absorption and are therefore at their most effective.
Moreover, a broad range of high-tech systems is on offer for the Variant. They cover technologies like Front Assist that includes the City Emergency Braking function; Automatic Distance Control (ACC); Lane Assist; Driver Alert system; road sign recognition and the latest generation of Park Assist; Light Assist and Dynamic Light Assist. More new systems have been added, such asprogressive steering; a newly developed ergonomic sport seat (ergoActive seat); a guard againstusing the wrong fuel in the diesels; and a new deluxe heated windshield. A driving profile selector is also a new feature: it has up to five modes -- "Eco," "Sport," "Normal," "Individual", and "Comfort". The last named is only available in in combination with the DCC adaptive chassiscontrol that is available for the first time on the Golf Variant.
Sophisticated infotainment. All Golf Variant models have touchscreen interfaces for their infotainment systems as standard. The new generation of systems is available with three different display sizes: 5 inches, 5.8 inches and 8 inches. Once you arrive at the mid-size screen, the displays have proximity sensors: as soon as the driver or front passenger moves a finger near to the touchscreen, the system automatically switches from display to input mode. The displays also have a function that lets users scroll through lists or browse CD covers in the media library with a swipe of the hand. Optional features include a high-end sound system by Dynaudio®.
New engine families. Just like the new Golf hatchback, the Variant uses two newly developedengine families - the EA211 gasoline engines and the EA288 turbodiesels. All Variants are fittedwith a Stop/Start system that reduces fuel consumption by up to four per cent and a batteryregeneration mode that cuts CO2 emissions by around three per cent.
The new Golf Variants have either a five- or six-speed transmission, depending on the engine. Most of the TSI® and TDI engines may also be combined with a DSG® dual-clutch automatic gearbox.
The EA211 turbocharged direct-injection gasoline engines produce 85, 105, 90, 122 and 140 hp. These engines are highly efficient: the 1.2-liter, 105-hp TSI BlueMotion Technology, for example, returns a combined figure of 46 mpg yet powers the car to a top speed of120 mph.
The new EA288 TDI diesel engines are incredibly efficient. The three high-tech diesels make 105, 110, and 150 horsepower, and return between 71 mpg for the BlueMotion and 56.0 mpg for the torquey 150-hp version.
