Hybrid diesel-electric motorcycles have been created having a top speed of around 800 mile per hour with a very affordable retail price of $500. Several known cars or vehicles manufacturers have also joined the bandwagon like Honda, Ford, General Motors, Mazda, Nissan and Toyota. These big names are currently innovating to continuously generate well-performing vehicles with all the advantages.

Hybrid electric vehicles have been very specific in being made available for future taxicab models. Since these automobiles are usually on the go all day long, fuel and emission can be improved through automatic engine shutdown, regenerative braking and idling. There are plug-in models in which taxicabs can conveniently recharge batteries at designated stands throughout the city. Plug-in hybrid electric models are also available in the form of sedans and mini-cars.
Hybrid-electric buses and trucks are also circulating due to the many advantages offered. The diesel engine is smaller which means that it is more efficient. There is also a 1.9-liter diesel engine instead of the 7.0, emitting less harmful gases. Emission reduction has been reported to be around 30% while fuel efficiency is around 40%. Some hybrid-electric buses have gas turbine generators. More efforts are exerted to convert other means of transportation like trains.
Several other types of hybrid electric vehicles are available today and are being used in various projects. The military uses diesel-electric hybrid trucks which has a fuel cell auxiliary power and diesel electric unit. The United States Army began using hybrid electric drives for all vehicle systems and subsystems. Other notable trucks have also found their purpose in commercial sectors, scientific projects and mining endeavors.

The Golf TDI has hybrid and electric motor that operates either with the diesel engine or separately. The Golf TDI hybrid uses a 3 cylinder common rail diesel engine with a displacement of only 1.2-liters. It produces 74-hp and 132 lb-ft (178.76 Nm) of torque. The Golf TDI electric motor is able to produce 27-hp and 103 lb-ft (139.49 Nm) of torque.
According to Volkswagen, the electric motor offers enough power to get the vehicle moving from a standing start. The diesel hybrid engine will only engage at higher speeds or extra acceleration (if required), as soon as the vehicle is in motion. Beside that, in order to improve fuel economy, the Golf TDI also rides lower than the standard Golf on an improved suspension and makes use of a unique front bumper to reduce drag.
Diesel hybrid concept: the Volkswagen Golf TDI
However, reports indicate that while Volkswagen is planning to produce a diesel hybrid, it won’t likely be this one. Citing the high cost of building a Diesel Hybrid as a factor, the company is anticipated to be going with a turbo—supercharged gasoline hybrid instead.
When it comes to high-end luxury sedans, you can not do much better than a Mercedes-Benz S-Class. The top-of-the-line four-door Mercedes offers massive amounts of comfort, gadgetry, performance, and style – just about the whole thing except fuel economy. The 2009 Mercedes S-600 model only achieves 11 mpg (4.7 km/l) in the city and 17 mpg (7.2 km/l) on the highway.
But the company showed off a concept S-Class Diesel Hybrid that can deliver more than 40 mpg (17 km/l) at the Frankfurt Motor Show in 2007. The Mercedes-Benz S300 BlueTEC Hybrid concept has a 2.2-liter diesel engine that drives the wheels most of the time, along with an electric motor to assist with acceleration. Overall, it produces about 224-hp and a whopping 413 lb-ft (559.32 Nm) of torque – numbers that are comparable to a powerful V8 engine.
The S300 BlueTEC Hybrid concept also uses Mercedes’ version of the AdBlue urea injection system, which allows the vehicle to meet the strictest of emissions standards. This is another potential 50-state diesel-powered car.
Many companies compete to improve better innovation to create more unique Diesel Hybrid concepts. At the Paris Show in 2006, Citroen, French automaker showed off its C-Métisse diesel hybrid concept car. The fire-engine red concept car was a low-slung four door coupe with swooping lines and huge wheel arches.
Better yet, the C-Métisse Diesel Hybrid very unusual setup – a 2.7-liter diesel V6 in the front of the car drives the front wheels, while two electric motors drive the rear wheels. According to Citroen, the V6 puts out about 208-hp and the two rear motors deliver about 295 lb-ft (399.51 Nm) of torque each. That’s enough to drive the vehicle from 0 to 62 mph (100 km/h) in about 6.2 seconds.
The car achieves about 45 mpg (19.1 km/l) with this setup. It can also run up to 20 mph (32.2 km/h) on electric power alone, where it operates in “Zero Emission Vehicle” mode. Citroën says the concept is very environmentally friendly, and is equipped with particulate control systems.
With their excellent performance, great fuel economy, and proven durability, why wouldn’t automakers produce Diesel Hybrid vehicles? Substantially higher initial cost may be the biggest factor, but as fuel prices climb, a Diesel Hybrid just may be in our future.

mpg on mercedes 2012 s300 Diesel electric hybrid car models have shown a lot of potential in terms of consumer demand and fuel economy. Because of the low existing numbers for diesel electric hybrid car in the United States, many analysts see the highest growth potential for diesel electric hybrid there. One of the reasons for this is that better fuel economy than gasoline, and therefore, the diesel electric hybrid are potentially capable of offering fuel economies that are better than the corresponding figures for gasoline hybrids.
VW Golf
Volkswagen is taking this opportunity and bringing diesel electric hybrid to the United States by releasing a version of the VW Golf which will be officially unveiled sometime in the latter half of 2009 and intended for the 2010 model year. This is going to be the first American version of a diesel electric hybrid vehicle, making it quite a sensation already though it has at least a year before its official release.
VW Golf (more readily known as the Rabbit in North America) has stated that the company aims to achieve a combined fuel economy of 112.49 kilometer (69.9 miles) per gallon US with carbon dioxide emissions of only 89 grams per kilometer (0.62 mile). In comparison, Toyota Prius delivers 88.5 kilometer (55 miles) per gallon with carbon-dioxide emissions of 104 grams per kilometer.
Unfortunately, diesel electric hybrid cars are very expensive to produce. If you combine a diesel electric hybrid engine, (which costs around $2,000 more than a petrol engine) with a hybrid powertrain, the end result is a very expensive system. Besides that, specific systems to treat the Diesel Electric Hybrid exhausts would increase the unit costs.

Editor’s note: Alexandra Paul is an actress best known for her four years starring in the television series “Baywatch”. She has been driving electric vehicles since 1990 and is a founding member of Plug in Americaexternal link. Paul can be seen in the documentary “Who Killed the Electric Car?” in theaters this summer.
LOS ANGELES, California (CNN) — I drive an electric car. Not a hybrid — a gasoline-powered car that gets some help from an electric motor — but a full electric vehicle. I plug it in at night and can drive 100 miles the next day and go faster than 80 mph on the highway.
So don’t think “golf cart”; these cars have power and pick-up.
While you won’t see many electric cars on the road, they’ve been around longer than you might think.
During 1900, electric cars outsold both gasoline and steam vehicles because electric cars didn’t have the vibration, noise and dirtiness associated with gas vehicles. However soon afterward — with the discovery of Texas crude oil that reduced the cost of gasoline, the invention of the electric starter in 1912 that eliminated the need for a hand crank, and the mass production of internal combustion engine vehicles by Henry Ford — the electric vehicle went the way of the horse and buggy.
The energy crisis in the 1960s and 1970s revived attention briefly. There was another push in 1990, when General Motors Corp. unveiled the (ineptly named) Impact, a sporty, aerodynamic electric car prototype.
In 1998 the California Air Resources Board decided that if a car company could make such a car, it should, and mandated that two percent of vehicles sold in the state in 1998 must be emission-free, with that number rising to ten percent in 2003.
Since California is a huge market, Honda, Toyota, Nissan, Chrysler, Ford and GM started building electric vehicles — about 5,000 were manufactured. But by 2005 the mandate had been eviscerated because of pressure from those same car companies, and 4,000 perfectly good electric vehicles were crushed.
But did car companies really want electric cars to succeed? The success of electric vehicles would have threatened the status quo and core business models of two of the world’s biggest industries — oil and automobile. It is more measure for these companies to give lip service to hydrogen in an attempt to appear “green.” But hydrogen is a technology that experts say is decades away.
Because the small print in California’s mandate allowed for car companies to manufacture only as many cars as there was interest in them, the game became to pretend there was no interest. Almost no advertising money was spent to let you know electric cars existed, and even if you did find out about them salespeople actively dissuaded you from getting one.
As with any new technology, an electric vehicle was more expensive than its gas counterpart. In addition, the limited range scared off customers, although the average American drives only 34 miles a day and every electric car could go at least twice that far on a full charge.
These cars had huge potential, but no media covered their subsequent crushing. It is only with the release this summer of the documentary “Who Killed the Electric Car?” that the full story comes out. This film chronicles the rise and fall of the General Motors EV1, an electric car I leased on the day it was released in 1996. Zero to 60 mph in 7.4 seconds, a top speed of 140 mph and a range of 120 miles. GM discontinued this car just a few years later. No car company nowadays makes a mass-production electric vehicle.
My current electric vehicle, a Toyota RAV4 EV, also was discontinued a few years ago. This car costs me the equivalent of 60 cents a gallon to run. I never need to get a tune-up, change spark plugs or add water to the batteries or oil to the motor. The only maintenance for the first 150,000 miles is to rotate my tires. This car is quiet, fast and emission free. I plug it in every night at home, and it charges on off-peak energy.
Even if it were getting power solely from electricity derived from coal — a common criticism of electric cars — my vehicle uses fifty percent less carbon dioxide than a 24 mpg gas car. When I have to get new batteries, which I expect I’ll will be when my car is ten years old, the old ones will be over 90 percent recyclable.
The concern I hear most often about electric vehicles is their range. Well, at 100 miles per charge, my electric vehicle fulfills 98 percent of my driving needs, and I live in a city where everything seems to be 40 minutes away.
When I want to go further, I borrow my husband Ian’s Toyota Prius. I don’t like driving it. Am I supposed to be amazed when a car gets 43 miles per gallon? The average fuel economy mandate for cars in 1985: 27.5 mpg. For 2006: 27.5 mpg. No wonder our expectations are so low. Progress in fuel efficiency has been glacial compared to improvements in computers and cell phones.
There is a solution: The plug-in hybrid. This vehicle will run on pure electric power for up to 60 miles, and then automatically switch to gas (or a biofuel) if you drive farther. For the reason that around 85 percent of Americans travel less than 50 miles a day, this means that the majority people who charge their cars at home each night would hardly ever dip into their car’s gasoline tank.
The infrastructure to charge is already in place (electric outlets are everywhere), and the technology (batteries) has been tested in the field and greatly improved upon for over 15 years. National security experts, including former CIA Director James Woolsey, are advocates for these vehicles because they say these vehicles can help break our dependence on foreign oil. Environmentalists support them because plugging in means getting an average of more than 100 mpg. Consumers like them because they will be saving thousands of dollars in gasoline costs.
Once you have known the quiet smooth speed and the clean efficiency of an electric vehicle, you will never think “golf cart” again.
