First of all, hybrid cars still use gas engines. So that throws out the point of trying to stop the world's draining oil resource. To even get anywhere, you have to use the gas engine. The electric motor is completely relied on, without the gas engine, on very, very low speeds. Sure, the electric motor is great for stop and start traffic jams, but the fact is that the gas is being used to charge the batteries. If you run out of battery juice, the car will rely completely on the gas engine until the battery is charged up.
Secondly, there's the cost. People may think "Oh, I'm not using gas all the time so I'm saving money on gas usage." Uh oh, it's too bad that hybrid vehicles cost so much more than their non-hybrid counterparts that a hybrid owner would have to drive twenty thousand kilometres a year for 5-10 years, depending on the cost difference, to make up the savings on initial cost. It's very impractical.
Third, there is the issue of speed. If you're not in constant congested roads, maybe you drive quite a lot on the highways or live in cities that don't have that much traffic, you're wasting more gas than the non-hybrid counterparts. The reason is the weight. It's common knowledge that more fuel is needed to drive faster, and you need to drive faster to achieve the same speed if you were carrying more weight. Taking a normal Camry versus a hybrid Camry, the hybrid has 161 more kilograms because of its hybrid engine and build. All that weight consumes more fuel to achieve the same amount of speed.
As a joke test, Top Gear ran a test with a Prius against a BMW M3. The Prius was driven at its top speed of SNORE (99 mph) with a 1.5 litre 4 cylinder engine. The M3 has a 414bhp 4 litre V8 engine. The result was that the Prius did 17.2 mpg (miles per gallon) while the M3 did 19.4 mpg. So not only is the Prius slow, but its gas engine is terribly made that the M3 can get more power from less fuel with its engine.
The conclusion is that hybrids are terrible.
But the one thing that bothers me the most is that all those news glanced over the car that will save the world.
The Honda FCX Clarity runs on compressed hydrogen and uses no gas. Hydrogen is abundant and there are hydrogen filling stations in California where they are testing hydrogen fuel cars. The only emission that comes out of the FCX Clarity is water, so why are the hybrids in the headlines and this car isn't? Sure, it's not available everywhere just yet, but if the world smartens up and demand and invest into hydrogen vehicles, we'd see them much sooner around the world.
