On a green drive

April 22 is Earth Day. Simply observing it isn't enough. Be a part of the green movement by going in for an environment-friendly vehicle.

Over the years, we have experienced how unpredictable the climate has become. Summers are hotter, when it rains — it pours, and winters are, to put it mildly, bizarre.

Carbon dioxide, nitrous oxides, water vapour, and methane — trap the sun's heat and light in the earth's atmosphere, causing temperatures to soar. There are other contributors to this damage but we'd have to admit, albeit grudgingly that automobiles are to blame too, despite their unquestionable utility value and the fact that we can't live without them. So what's the solution?

Well, governments, automobile manufacturers and researchers are already striving to make our vehicles green. Air pollution legislations are getting stringent, there is an increased focus on green fuels and green cars, and the idea of cars that emit water as the only emission does not appear far-fetched now. Manufacturers are also working to produce cars in the most energy efficient manner possible.

As motorists, we need to get our act together and be part of the solution. The time is ripe for a green revolution on wheels. If you're looking to buy a green car, we've compiled a list of cars to make that decision easier. You'd be surprised by the many green car options. We have omitted a few since it runs too long.

April 22 is Earth Day. Simply observing it isn't enough anymore. It's time for action.

Hyundai i10 CNG

Hyundai wants to make its i10 appeal to as many buyers as possible, eco-conscious customers being part of that list. Little wonder why a CNG kit is offered as an option on the car. The CNG kit adds Rs. 55,000 to the price of the petrol model that starts at Rs. 3.54 lakh (ex-showroom, Delhi). Buyers will like its city-friendly dimensions and cheerful interiors. Good fuel economy in petrol mode and low running costs in CNG mode make the i10 CNG an excellent eco-friendly buy.

Maruti Suzuki Alto Green

The Alto Green is the CNG variant of the hugely successful Alto. The hatchback features Maruti's intelligent-Gas Port injection (i-GPi) technology that promises more power and better fuel efficiency than retro-fitted CNG kits. The Alto Green is powered by a 796cc engine that produces 38.8bhp in CNG mode. Extremely low running costs make this a great buy for those on a tight budget. The Alto Green is available from Rs. 2.78 lakh (ex-showroom, Delhi).

Toyota Innova CNG

Toyota's ever-popular Innova can now be had with a CNG kit. Offered as an optional on the 2-litre petrol eight-seater model, the CNG kit adds Rs. 1 lakh to the base price of Rs. 8.95 lakh (ex-showroom, Delhi). The 12kg CNG cylinder tank is housed behind the third row seats and this limits luggage space. However, if a large, good quality and inexpensive-to-run people-carrier is what you need, the Innova CNG is the answer. At present, the Innova CNG is only available in Mumbai and Delhi-NCR region.

Chevrolet Beat LPG

Here's one way to beat rising petrol prices. Chevrolet has recently launched the LPG version of the Beat hatchback. Powered by a 1.2-litre Smartech engine, the Beat LPG comes with a 28-litre LPG cylinder in addition to its 35-litre petrol tank. Chevrolet claims this Beat can cover 349km on one tank of LPG, and with combined fuel usage, it can stretch its legs till 1,000km. Prices start at Rs. 4.11 lakh (ex-showroom, Delhi).

Tata Indica eV2 LPG

Tata Motors has recently updated the Indica hatchback, now called the Indica eV2. Mild exterior and interior tweaks have revamped this decade-old car. The Indica continues to sell with an LPG option. Power is courtesy a 1.2-litre engine that develops 61.8bhp. The Indica eV2 LPG is a high-value product being big on space and low on price. It sells for Rs. 3.3 lakh (ex-showroom, Delhi).

Mahindra Scorpio micro hybrid

Mahindra's flagship SUV has made it to our green list thanks to its innovative Start/Stop technology. The engine cuts off when the car is idling. Sadly, this switches the AC off as well, leaving only the blower on. A handy switch de-activates the system for those hot summer days. Big and green, the Scorpio Hybrid is available Rs. 10.36 lakh (ex-showroom, Delhi) and upwards.

Toyota Prius

The Prius is that dollop of salad you take onto the plate after gorging on all those fried starters. Arguably the world's most famous hybrid, the Prius might just be that evolutionary pivot Darwin was harping about. Its electric motor works at crawling speeds and keeps emissions to a minimum. And 136bhp from its petrol engine means it is not found wanting for power. An ideal green car. Pity it costs an exorbitant Rs. 27 lakh (ex-showroom, Delhi).

Mahindra REVA i

The Mahindra REVA i is the sole electric vehicle sold in India. Zero emissions make it the greenest car here. While the styling may not appeal to all, it can be called cute. The i comes with a lead acid battery which the company claims gives it a range of 80km per charge. A simple wall socket is needed to juice up the battery that takes 2.5 hours for an 85 per cent charge with a full charge taking eight hours. Pricing starts at Rs. 2.85 lakh (ex-showroom, Delhi). It's worth noting that the all-new Reva NXR and NXG cars with more powerful batteries are being readied for launch.

BMW's hybrid X6 accelerates nonsense about fast low-emission cars

BMW is launching the 'world's most powerful hybrid' at Frankfurt motor show but its eco-friendly claims are weak

It's the holy grail for motorists with a green conscience – a high-performance eco-friendly hybrid car. Well, that is what BMW will have us believe when it unveils its latest model at the Frankfurt motor show in Germany next week.



The show is likely to see a stream of new hybrids, cars that combine a combustion engine with an electric motor for improved fuel efficiency. And pole position is likely to be taken by BMW's ActiveHybrid X6, which it styles the "world's most powerful hybrid".

The new X6 goes from 0-60 mph in under six seconds and has a top speed of 130 mph.

But the company gives equal prominence to its pitch that the new hybrid is "eco-friendly", because its carbon emissions are 20% less than those of a regular X6.

For a few days last month you could read the same claim on the website of the Energy Saving Trust, the "impartial" adviser on energy efficiency set up by the British government.

But is it too good to be true? Of course. As one incredulous reader who spotted the story on the Trust's website pointed out: "The Trust is promoting a car as eco-friendly with emissions TWICE that of my 6 year old Honda Civic hybrid!"

The ActiveHybrid X6's official CO2 emissions rating with the European Union is 231 grams per kilometre. That compares badly with the EU's 2012 target for average emissions from new cars of 120 grams. It is also higher than the emissions from most of the new Lexus hybrid range and more than twice the emissions of a Toyota Prius, for instance.

The fact that it is better than the regular X6's rating of 299 grams per kilometre does not make it eco-friendly, I am afraid. The claim is greenwash.

I suspect we are going to see a rash of these high-performance high-emission hybrids masquerading as green. Back in the lab, BMW is developing a hybrid "supercar" that will reach 155 mph and 0-60 mph in less than five seconds.

Sure, hybrids are more fuel-efficient than the equivalent old models. The key is that the fuel does not have to be burned in inefficient surges as the car accelerates and brakes. It can be burned efficiently in a smooth flow, and the energy transferred to a battery that supplies the electric motor that drives the car itself. The battery can also make use of energy generated during braking.

But to call these high-performance models eco-friendly, or low-emissions as they burn up the autobahn is nonsense. They are, in reality, slightly less polluting gas-guzzlers.

The Energy Saving Trust seems to take a similar view. When my correspondent pointed out the dodgy nature of the car's green credentials, the offending story swiftly disappeared from its site. "Once we noticed it, we removed it straight away," a spokesman told me.

The rise of these new hybrids has important implications for green-minded legislators. For instance, it should increase the pressure on London's mayor to reconsider his blanket exemption from congestion charges for hybrid cars. Surely, only truly low-emitters should qualify.

Interestingly, the BMW PR promotes the idea that the driver of the hybrid X6 can "experience silence without coming to a stop", while the electric motor is running alone.

It sounds fun. But speaking as a pedestrian, I'm a bit scared at the idea of a car that can go from 0 to 60mph in less than six seconds without making any noise. Green or not, it sounds like a stealth killer.

GM’s New Hope in Chevy Volt

General Motors have long recovered from bankruptcy and rearing to show the world its grit in car manufacturing. The proposed launch of the electric vehicle, like none before, is a very good example of this above statement.

Brushing aside the fact that seeing is believing and taking into consideration the past glory of the company one could believe that the assured car from GM, Chevrolet Volt, will be seen in the roads by 2010, as per the promise.

The car has many peculiarities and it is expected to mark a strong comeback by General Motors. The Volt being an electric car and is also an eco-friendly car. By 2010 or 2011, it is expected that the demand for electric cars will increase and General Motors, as it looks, believes in this prophecy.

The Volt is a hybrid car that runs on lithium-ion batteries, the best to start with to begin the list of specialties. The car, like other electric cars, need not be taken to a station for charging their batteries.

The batteries could be charged through electric power or gasoline engine, at the comfort of your home of office or where ever you are, because it just needs a 120-240V AC electrical outlet. It certainly looks like General Motors has bounced back in the big league once more.

The Chevy Volt is powered by a 150 hp electric motor and a 1.4 liter 4 cylinder engine, and with the fully charged batteries of the Volt one can commute around 40 miles.

With more than a handful of hybrid cars and more to be launched by 2011, it could be a tough sailing for the Volt.
