Chrysler's Ram Plug-In Hybrid Pickup Truck

Hybrid pickup trucks are a rarity with only General Motors daring to offer this technology in its full size Chevrolet and GMC models. GM's hybrid technology isn't as sophisticated as what you would find in the Toyota Prius or Hyundai Sonata Hybrid, but it is sufficient enough for these burly trucks to achieve 20 mpg around town. That's significant in a market where 15 mpg combined fuel economy is the average for gas powered pickup trucks.

Chrysler Hybrid Quest

Chrysler briefly sold a pair of hybrid sport utility vehicles just before it went bankrupt in 2009, but pulled those models after a few months as the cost didn't justify the few sales it was able to gain. Yet, the automaker hasn't given up on hybrid technology as it is currently testing a fleet of plug-in hybrid Ram pickup trucks under the auspices of the U.S. Department of Energy.

The Ram plug-in hybrids or PHVs are among 140 prototypes being tested by the Chrysler Group in a dozen cities nationwide. Cities with disparate weather conditions have been chosen and range from Fargo, N.D., to Yuma, Ariz. These two cities offer the weather extremes the automaker needs to see how robust its hybrid technology is. The thinking is that if these trucks can survive winter weather where temperatures plunge to 40 degrees below zero or summer heat pushing 120 degrees, then the technology may be made available for retail sale.

Eight of the 10 PHV Ram trucks will be sent to Yuma's police department and used on patrol. The two remaining trucks will go to utility companies. A variety of public and private entities will partner with Chrysler in the other cities.

Federal Research Study

The Chrysler PHV program is being funded by the federal government, whose interest in the project comes as higher fuel economy ratings are being weighed. The standard Ram pickup truck gets a combined 15 mpg city and highway driving, but researchers expect that the PHV models will see a 50 to 60 percent boost in fuel efficiency. Researchers want each truck to put in at least 16,800 miles annually to accurately gauge results.

Each truck can run on electric-only power for 50 miles before the gas engine kicks in. Chrysler has no plans to offer the Ram 1500 PHV for retail sale as the program is part of a U.S. Department of Energy study. However, the technology may someday find its way into a production vehicle, perhaps the next generation Chrysler Town & Country minivan or the Dodge Durango crossover.

Cadillac Plug-In Hybrid Plans In Doubt

One of the more significant auto trends developing in summer 2011 and beyond are the number of plug-in hybrid electric vehicles arriving on the market. Ford and Toyota are getting vehicles to the market first, with Hyundai, Chrysler, Mercedes, BMW, Honda, Nissan and others expected to follow. GM will offer up at least one model, but it won't be the anticipated Cadillac crossover some had expected. In May 2011, GM canceled the project, citing cost as the main reason.

PHV Technology

Plug-In hybrid electric vehicles are not cheap to build as these models require a significant investment from the automaker without a guarantee that that buyers will embrace these vehicles. The advantage of a PHV -- or PHEV as called by some -- is that you can plug one in at home via a standard outlet. Some models, including the upcoming Toyota Prius Plug-In can be recharged in as few as three hours with a regular 120v outlet. If you have a 240v outlet, then recharging times are cut in half.

Cadillac had been expected to get some sort of hybrid or electric model to supplement its fleet, and was originally tabbed with getting a lux version of the Chevrolet Volt. That initiative was scrapped, but was followed up with a PHV crossover that would have been based on the SRX. However, GM wasn't prepared to commit money to a project with no certain upside available. Besides, the Chevrolet Volt itself is a costly endeavor, one that has cost GM hundreds of millions of dollars to launch and maintain.

Buick eAssist

What seems likely for Cadillac is getting some version of the eAssist hybrid technology slated to appear in the Buick Lucerne and Buick Regal later this year. This "partial" hybrid works with a small electric motor that offers part time hybridization, but at a lower cost than a standard hybrid system. The advantage for the consumer is twofold: fuel economy rises by about 25 percent and costs are about half that of what full hybrid owners pay.

This could mean that the current Cadillac SRX model itself will benefit from the Buick hybrid. Installing such a system could bump up fuel economy to 35 mpg on the highway, giving Cadillac a hybrid to compete with the Lexus and one that simply isn't an Escalade.

Cadillac Choices

In any case, GM will have to come up with a new plan for Cadillac as it faces increasingly stiffer fuel economy requirements courtesy of the federal government. A PHV, electric vehicle or partial hybrid would offset the gas guzzler Cadillac Escalade, but only a partial Buick-inspired hybrid system seems cost effective.

How the Plug-In Toyota Prius Changes Things

The Toyota Prius is the best-selling hybrid vehicle in the world, a vehicle introduced in 1997 and now claiming more than 1 million units sold. Toyota is ramping up production and expanding the Prius family and may soon sell 1 million units annually worldwide if demand continues to rise. High gas prices are bringing customers in, but even if gas prices plummet, the value of a Prius remains.

Toyota Recovers

This is good news for Toyota which has endured a devastating earthquake and decimating tsunami. As we head through the summer months, production on several Toyota models remains curtailed as suppliers seek to rebuild and as Toyota fixes manufacturing plants which have sustained damage.

Once Toyota works through its issues, the other side should be much brighter. Big on its list is the Prius line, expected to be expanded as three new models are released beginning in fall 2011 and through spring 2012. One of the three models is a plug-in version of the current Prius, a model that will enable some customers to enjoy amazing fuel economy without incurring the steep cost of paying for an electric vehicle.

Hybrid System

The Toyota Prius Plug-In will use the company's familiar hybrid system, but with some differences. Mainly, its electrical power will be generated from an outlet, allowing the car to run on pure electricity before switching over to gasoline. The electric only range hasn't been announced yet, but it if it mirrors the Chevrolet Volt's range, then drivers may be able to travel 35 miles without consuming gasoline. For owners who do a lot of around town driving, the Plug-In Prius could keep them away from gas pumps or at least reduce their visits significantly.

Once the Prius Plug-In exhausts electricity, it automatically switches to gasoline power, extending its range to about 475 miles. This amounts to nearly 100 miles longer than the Volt. Of course, both cars can be refueled at a service station. These models can be recharged in a matter of hours.

Choice Toyota

No other differences between the Plug-In Prius and the regular Prius exist. Both hybrids will be produced, although customers can expect to pay a price premium over the standard model. Likely, the Prius Plug-In will significantly undercut the Volt and perhaps even be priced below the Nissan LEAF, an electric vehicle with a range of about 90 to 100 miles.

In any case, the Prius is a choice Toyota product, one that is certain to be considered by EV fans who value price as much as they value saving fuel.

Fisker Karma, A Luxurious Plug-In Hybrid Electric Vehicle

The Fisker Karma is the most luxurious and high end PHEV available for sale in the United States. Electric cars haven't always been the most comfortable vehicles to drive, but Fisker Automotive is changing that with the Fisker Karma. People who crave luxurious cars can finally have the best of both worlds; the green energy of an electric auto and the magnificent driving experience they want.

Fisker Karma plug-in hybrid electric vehicles are rolling off an assembly line in Finland.

Former Aston Martin designer Henrik Fisker proudly unveiled his original Karma PHEV at the 2008 North American International Auto Show. It was an exciting concept, and it set the bar for other manufacturers. Going into 2012, the Karma is ready for full production, and it promises to be a very exciting year.

Valmet Automotive, current manufacturer of the Porsche Cayman and the Porsche Boxster sports cars, will be proudly assembling the Karma Plug-in Hybrid Electric Vehicle. Buyers can rest assured that their cars have been assembled by teams of highly skilled and professional artisans who have years of experience behind them.

Funding rescheduling forced Fisker Automotive to delay the release date of the Karma by two years. Originally slated to hit showroom floors in late 2009, the company now has initial deliveries scheduled for March 2011. President Obama has a clear goal of seeing one million electric vehicles on the roads by the end of his administration. Together with Gov. Jack Markell, Fisker Automotive was lent $550 million to help them get the cars into showrooms. The Karma sports sedan retails at $96,000 and has already rolled off Finland assembly line. The company's goal is to produce 115,000 cars over the next few years, and experts question if that goal is perhaps a little too aggressive.

Fisker Automotive, however, is undeterred. Not only did they roll out the Karma S convertible, a hardtop and stylish two door convertible, at the 2009 North American International Auto Show in Detroit, Michigan, they are also planning another luxurious green auto called the Nina. The Nina Fisker will be a modestly priced $50,000 sedan and the Boxwood Road plant will have the honor of producing it. The company is also planning on releasing an SUB and a coupe in the next few model years.

These are all lofty goals for a company that is essentially brand new and just getting started. Even wit the government assistance being provided and the incredibly exciting cars they are going to offer, it is still a challenge. The technology is revolutionary, and not yet fully embraced. Some analysts feel that the venture is doomed to failure, given the high price tags and the lack of public awareness about what these cars can really do.

The Karma is a brilliant electric luxury car, and it needs brilliant marketing to get the target audience into the showrooms. It's important that Fisker Automotive review the fate of the Smart Fortwo vehicle. A great design, the marketing was not effective and the sales proved to be lower than anticipated.

Three long years have passed since Henrik Fisker lent his experience designing Aston Martins to creating a luxurious plug-in electric hybrid vehicle. The road has been long and challenging, and it would be truly tragic to see it dead-end in failure due to ineffective marketing. The Karma features a 2.0-litre direct-injection and turbocharged four-cylinder gasoline engine that is actually produced by GM. The power is a strong 257bhp and the engine is designed to run at maximum efficiency as much as possible. The combustion engine actually works to feed a generator which then power the two drive motors.

Each drive motor creates 105kW of energy. The primary power source is the 20kWh lithium-ion battery pack, which consumes the aluminum backbone chassis. Plugging in the battery for an eight hour charge cycle will create enough stored energy for drivers to run about 300 miles, more than enough to run their errands the next day. Charging the hybrid to full power will cost about $3.00 each time.

Unlike other electric cars that are weak on power, the Karma can hit 60 mph in an impressive 4.6 seconds. The top speed is 125 mph, but there is a 90-second over-boost that will allow the driver to go up to 143 mph. The early figures on fuel consumption show that the vehicle will travel anywhere from 81 to 118 miles on a single gallon of gas. Naturally, how aggressive you are with the accelerator determines how far that gallon of gas will take you, and how often you will need to visit the corner gas station.

Those people who are striving to conserve as much power as possible can also choose the truly eco-friendly 'Stealth-mode'. When this is used, the electric luxury car will require about 6.5 seconds to reach sixty miles per hour, and the top speed will be a still-impressive 95 mph. The Karma can go fifty miles before producing any emissions when driven in ideal circumstances. This mode also prevents the engine from turning on at all unless the batteries are low and it is truly needed.

There are some other interesting aspects of this fine sedan. When batteries are fully charged, and it is coasting down a hill in regeneration mode, there is nowhere for the surplus energy to actually go. Therefore it goes to work turning the engine at a very low rpm. The vehicle is a lightweight 959 pounds, but getting that metal to move still requires a bit of power. To prevent the tires from squealing and twisting, the ESP switches to overload, helping to save the tires and extend their life. The ESP calibration is being fine-tuned, but this is a fine feature that is very exciting and revolutionary.

The Karma also has double-wishbone suspension in both the front and rear with self-leveling dampers in the back of the vehicle. The sub-frames are isolated and the tires are specifically made for these vehicles. They have taller sidewalls, creating a softer, more luxurious ride. Rack-and-pinion hydraulic steering with power assist makes it easy to maneuver. From lock to lock on the steering wheel is 2.7 turns, making the car fun and exciting to handle. The braking systems have been reviewed and are found to be fantastic at getting the car to stop smartly and safely.

The Fisker Karma has been much anticipated. Three years of waiting is finally nearing an end, and this luxurious and environmentally friendly sedan will be hitting showroom floors. Inexpensive to drive, with impressive range and a truly luxurious feel, this auto will be exciting to drive. With more exciting models being released, including the Nina Fisker and the Karma S convertible, there is a lot to be excited about. Owners are sure to ride in them proudly and often. It is the perfect vehicle for any lover of luxury automobiles who also cares about protecting the environment.
