Hybrid Cars Vs Clean Diesel


Automobile producers are producing a great deal more eco-friendly cars and trucks these days. Most solutions you will see on the market in the US market are hybrids, yet, there has been a slow exposure to a second option - clean diesel - brought to you by the European vehicle makers. These two designs of eco-cars are both advantageous to the environment. The Toyota Prius reigns supreme in the hybrid sector and the Volkswagen Jetta TDI is working itself into a very competitive marketplace and makes for a superb comparison. Both the Prius and the Jetta are terrific compact sedans that give unique technologies to buyers who are in the marketplace for an eco-friendly vehicle. Looking at their combined fuel economy and emissions, their performance and comfort, and their overall value, a buyer can far better decide which direction to go for their next "green vehicle" buy.

The technologies that powers the Toyota Prius is the hybrid approach (dubbed by Toyota as their "Hybrid Synergy Drive" method). This technology makes it possible for for the simultaneous use or independent use of two separate power plants. The first power plant, a 1.8 liter VVT-i (variable-valve timing), four-cylinder, gasoline engine produces 98 horsepower. The second power plant comes in the form of a 650-volt Nickel-Metal Hydride (Ni-MH) battery-powered electric motor capable of producing 36 horsepower, and when combined with the gas motor, they produce 134 horsepower. The Hybrid Synergy Drive system makes it possible for the gas engine to be used in the course of high acceleration or throughout high speed travel independently, while the electric motor can be utilised for the slower in-town driving entirely or can help the gas motor when required. This method significantly improves the gas efficiency and keeps the emissions incredibly low. The Prius is capable of finding 51 MPG zipping via the city and 48 MPG for highway travel, while only emitting 8,688 lbs of CO2 a year during an simply driven 15,000 miles of use and only expect to pay an annual price of $819 in fuel.

As far as performance goes, do not expect a miracle. Nevertheless, by hybrid standards the acceleration is not that poor. The Prius is capable of obtaining you from a stand-still to 60 mph in 9.2 seconds. Not sports-automobile quickly, but remember this is a green, gas-sipping compact sedan. Couple that with the independent suspension and you are in for a quite enjoyable ride. The interior is particularly spacious for a compact car as nicely. The Prius seats 5 and has an interior passenger volume of 93.7 cubic feet. The cargo capacity will allow up to 21.6 cubic feet for those lengthy trips or busy supermarket days.

Some may anticipate hybrid car's to have a high MSRP, but the entry price of the Prius is surprisingly low. The beginning MSRP for the Prius is $22,800. Add on some high-tech options like solar powered ventilation, collision detection and GPS navigation and the price can jump to properly over $28,000. Toyota will also back your purchase with a three-year/36,000 mile bumper to bumper warranty, a 6-year/60,000 mile powertrain warranty along with an 8-year/80,000 mile warranty for hybrid component systems. Now on to the competition.

The Volkswagen Jetta TDI implores a entirely distinct type of technologies, a turbo direct injection (TDI) diesel engine that produces 140 horsepower and a staggering 236 lb-ft of torque. Now, this diesel engine is mechanically no diverse than other diesel engines except for the reality that it is capable of utilizing Ultra-Low Sulfur Diesel (ULSD). This cleaner diesel fuel contains lower sulfur amounts than the previous diesel fuel of the past. In truth, ULSD contains 97% less sulfur than the older standard of diesel contained (15 ppm vs. 500 ppm). This new regular was to be totally implemented in the United States by 2010 by all fuel stations and refineries and is mandated by law. The use of ULSD permits the Jetta TDI to implement pollution technologies that will filter out the other emissions that come from the burning of the diesel.

Given that the Jetta takes benefit of the technologies it uses to lower emissions, the fuel economy of the auto is improved as nicely. This diesel sedan can get 30 MPG in town driving and 42 MPG on the highway. In a year, driving 15,000 miles, the Jetta TDI outputs 10,717 lbs of CO2 and will run you about $1,314 in fuel price. The optional 6-speed manual transmission or 6-speed automatic sport-shift transmission make the Jetta sportier and much more fun for the driver. These choices also allow the Jetta to edge out the Prius in the -60 stat by 1 second or so at 8.2 seconds. The Jetta's cabin can seat five as nicely, but lacks in the interior volume compared to the Prius, only supplying 91 cubic feet of space for it is passengers. The cargo space is also much less coming in at a mere 16 cubic feet.

A clean diesel Jetta TDI will cost you a minimum MSRP of $22,830. The high-tech capabilities for the Jetta pale in comparison to the Prius, still, premium options such as GPS navigation, chrome side mirrors, body kits as well as bigger alloy wheels can take you well over $27,000. Volkswagen will back your Jetta for 3-years/36,000 miles bumper-bumper, a powertrain warranty of 6-years/60,000 miles and they top it off with a no-price scheduled maintenance of the Jetta for three-year/36,000 mile coverage.

Ultimately, if you are getting the car for an eco-friendly obtain, the Prius is still on top. In the world of green automobiles, gas mileage and CO2 emissions is king, and the Prius delivers on all fronts. Regardless of the sportier advantage the Jetta TDI provides, it is still far from the preferred selection of these two green cars. The clean diesel vehicles have not however become competitive enough to win this battle, then again, word of a Mini Cooper D coming to the United States is beginning to take wind and is getting 72 MPG in Europe, but we shall see. Either way, a clean diesel or a hybrid vehicle are a much greater alternative to a standard gasoline vehicle if you are attempting to purchase "green".
