The new 2011 BMW ActiveHybrid 7 happens to be hybrid car that bears little resemblance to a Toyota Prius or other similar hybrids. Whenever you primarily think of hybrid, you think fuel performance, but the BMW hybrid is nowhere near as efficient as most hybrids. The 2011 ActiveHybrid 7 is the most fuel-efficient of the 7-series model, but its power steering is shut down by the idle stop feature, and it doesn’t work well in stop-and-go traffic. It can do a good job of incorporating raw car power with the fuel efficiency of hybrid technology but there are numerous quirks that get in the way.
Most hybrids have a smaller gas engine since the car is also being powered by the electric motor but this is not true for the BMW ActiveHybrid 7. BMW made a decision to make use of the extra power produced by the electric motor to make the car go even faster instead of using it to reduce fuel consumption. The 2011 BMW ActiveHybrid 7 contains a double turbo direct-injection 4.4-liter V-8 engine which is the same as the basic BMW 750i Unlike the BMW 750i, the ActiveHybrid 7 contains a 120-volt lithium ion battery supply. This makes the gasoline economy of the ActiveHybrid 7 better than the 750i, and with a lot more horsepower also. This generally provides more than BMW 525i series.
A lot of hybrids are able to switch to all-electric mode even so the ActiveHybrid 7 does not do that. It is similar to the Integrated Motor Assist System of the Honda, where it offers boost when it is speeding up, and when it stops it lets the engine shut down. If driving, you will have no idea that it is a hybrid barring when you see a blue are in the fuel monitor to show that electricity is being regenerated. If the car stops at a traffic light, you will know that it is a hybrid, by the engine going noiseless and the tach needle drops to zero. In spite of the proportions of the engine, the vehicle starts up very smoothly when you take the foot off the brake pedal.
While the idle stop system works well at a long stoplight, it won’t do so well in stop-and-go traffic. The vehicle will have a tendency to shut down for 5 seconds at a time which can end up getting irritating after awhile. The performance of the vehicle may also take some getting used to because it is likely to lunge forward even with a slight tap on the accelerator. This does not appear to be a very eco-friendly car but the intent behind this hybrid is to add power more than improve fuel efficiency.
Fuel performance is pretty relative when you compare it to other hybrids where it is more efficient than other BMW 7 series models but it get 20 miles per gallon. Not bad for the luxury vehicle it is, but nothing exceptional for a hybrid. Most expect we can discover ActiveHybrid in BMW 525i as well as alternative BMW wagon in the near future?
It seems that the hybrids car is all the rage. News reports crow regarding their many miles per gallon and low emissions. Hybrids are amongst the best-selling models in America for both American and foreign car makers. And hybrids do not need to be compact – there are even hybrid model sport utility vehicles (branded as SUVs, in brief).
Some consumers are left scratching their heads regarding all this hullabaloo. Why should a hybrid car be so eye-catching to many people? One reason, needless to say, is soaring gas prices. While the price of crude oil shoots up, whether due to short-term problems like those in Libya or long-term problems like depleting global petroleum reserves, the price of gasoline at the local gas station rises also.
Mainly because hybrid cars (so named because they are powered by two fuel sources: electricity and gasoline) use less fuel, they offer savings to the consumer over the life of the car. However hybrid cars also are more expensive than ‘normal’ cars. That cost is driven mainly by the price of the new, patented technologies unique to each car maker. But it also owes it to the expensive component parts, such as those used to make the bigger batteries incorporated in the car.
Whether even the best hybrid car really ‘saves’ any money will depend on how much fuel prices rise while the car is used. However another reason (and one which makes more mathematical sense than fuel prices) is concern for the environment. Even if, as seems probably, a hybrid car will cost more over its lifetime than an equivalent gas-powered car, it will be better for the environment.
There are two reasons hybrid cars benefit the environment. First of all, hybrids use less gasoline, and thus less crude oil. Because oil is a diminishing resource used for lots of things besides fueling cars, using less of it benefits everyone and moves us closer to a sustainable economy. What is implied by sustainable? Sustainable economies are the ones that do not deplete their resources to zero.
By utilizing less fuel, hybrid owners move the world (slightly) nearer to a sustainable global economy, whereas in the current economy it is predict that global petroleum reserves will expire sometime this century. This benefits the environment mainly because many cheap alternatives to petroleum emit more air-borne pollutants when burned: coal, for instance. The second way that hybrids benefit the environment is by emitting much less exhaust fumes.
Because hybrid cars do not use their internal combustion engines consistently, but instead are powered sporadically by stored electricity, they burn much less fuel. A consequence of burning less fuel is that they also spout fewer exhaust fumes into the air. This benefits the environment in a number of ways. First, of course, it enhances air quality on the ground. Car exhaust fumes are terrible for people, and reducing the amount in the air helps make everyone healthier.
Second, car exhaust fumes contain carbon dioxide, which can erode the world’s ozone layer. That could, in turn, give rise to global warming (some scientists say that it already has). So it is easy to see that while hybrids might benefit their users if gas prices sky-rocket, they benefit the world much more, by reducing reliance on crude oil and cutting emissions of carbon dioxide into our air, both at the ground level and in our atmosphere. Which is a very big deal.

There’re loads of automobiles available today, however with gas prices going nowhere but up, you probably wish a car with good gas economy. Luckily, there’re increasingly more alternatives for fuel efficient cars, so that you can have a car that matches you and your requirements. No more is one bound to a specific type of version or brand name. Fuel efficient automobiles in 2012 are diverse and give some pretty impressive savings. With gas prices expected to someday soon rise to $5 per gallon, you wish to ensure you are getting the most from each and every penny.
Undoubtedly, the Toyota Prius family are the best 2012 fuel efficient cars. There’re many different types of the Prius now, rather than just one or two styles, there are now four various Prius versions to provide you more alternatives and match your needs. There’s as well the Nissan Leaf, which is 100% electric and completely eliminates your requirement for gas or diesel. Sadly this version and other electric vehicles are not meant for long-distance traveling; but there are many different hybrid options if you want a car for more than just local trips.
Some automobiles such as the Chevy Volt offer remarkable mileage on a single tank of gas by utilizing electricity and gas- the first 35 miles approximately after charging is completely gas free and uses electricity. There’re many more automobiles that are utilising hybrid technology or just improving fuel efficiency overall. Honda has many hybrids and gas efficient automobiles such as the Honda Civic Hybrid, providing an impressive 41 combined mpg. The elegant Honda CR-Z provides 37 mpg combined, for those wanting a sporty however gas efficient vehicle.
There is also the stylish Ford Fusion Hybrid coming in with an also impressive 39 combined mpg. The Ford Fiesta is additionally quite a sporty compact vehicle at a low cost, and has a respectable 33 mpg combined, or up to 40 mpg on the highway. If you don’t require much cargo space and just want a low cost vehicle with great gas mileage, the Smart for Two is best with and starting at $12,490 MSRP. Another good brand for gas efficiency and best price is Hyundai, providing many vehicles with great gas economy and alternatives all at an affordable price. Hyundai has for years had the best warranty in the states, that can make it even more worthwhile if you are planning on keeping your automobile for a few years or more.
Regardless, there’re many various versions and options now for fuel efficient cars in 2012. It’s become a thing of the past to be limited to just one or two brands and limited variety. Thanks in part to increased government fuel standards, increasingly more automobiles and trucks in general have a fuel economy of 25 mpg or perhaps 30 mpg, but 2012 brings us a number of different vehicle choices for cars getting 35 or even more mpg. All the leading brands now offer more alternatives and choices for fuel efficient automobiles, and the trend is undoubtedly anticipated to continue.
