Last week the caller-up showed the ESX3 to the press in Washington, D.C. , an event which marks the exertion of the first official milestone of the 10 year-long USPartnership for a New Generation Vehicle program in which all three US car makers have now developed fuel-efficient, high mileage vehic les. From the arising of the ESX program, DaimlerChrysler engineers have sought ways to not besides achieve the performance goals of PNGV but have striven to bowdlerise the cost premium associated with hybrid electric technology. In the ESX3 they have cut the cost in half(prenominal) from the $15,000 of the ESX2 to just $7,500 in two years time.The quintuple passenger ESX3 achieves 72 mpg, up two miles from the more aerodynamic ESX2. Its mild-hybrid or mybrid drive check takes a similar approach to that of both interbreeding and GM PNGV cars, mating a 1. 5 liter, all aluminum direct-injection diesel engine engine to a 15 ki depressive disorderatt electric motor. Like the Toyota Prius, the 106 pound atomic number 3 ion bombardment pack is wedged between the foster passenger seat and trunk which provides 16 boxy fee (450 liters) of cargo space. An important component in of the ESX Mybrid constitution is its EMAT transmission system which utilizes two computer-controlled clutches.The EMAT system combines the smoothness of an automatic transmission with the added fuel efficiency of a manual. The driver sees the normal selection of park, drive, inert and reverse. One of the most remarkable features of the ESX3 Mybrid drive is its weight which is less than a conventional gasoline engine. The three-cylinder diesel weighs just 250 pounds (113kg) and the air-colored electric motor just 76 pounds (33kg). DaimlerChrysler says that the ESX3 determines all the emissions targets originally set in 1993.However, it acknowledges that at that place is still much to be done to meet future emissions standards including further work on low sulfur and synthetic fuels, new exhaust aftertreatment technologies and fresh combustion processes. OMAHA, Nebraska April 19, 1998. Sport utility vehicles are hot Sales of the truck-like vehicles are roaringing in the USA. Once the purview of Jeep, Ford and Jimmy, now close to every car maker has entered the fray including Mercedes and Lexus. And the family line buying these behemoths dont seem deterred by their hefty sticker prices and the 70s era gas mileage that comes with them, not to mention a truck-like ride.While questions are now universe brocaded about both their environmental impact and safety, gross revenue continue to soar. The plain item is, Utes are in. After two years and 300,000 total hotheaded miles in Japan and the US, late last year Toyota began leasing a sensible sport utility vehicle that offers many of the perceived benefits of the standard Ute, but with correct tailpipe emissions. While the RAV4-EV shares many features, including body styling and interior appointments, with its IC-engine sibling, the similarities curiosity there.As Mark Amstock, Toyotas manager of North American Alternative Fuels Program, states in the video that accompanies this feature, the RAV4-EV is not a conversion. It has been engineered from the pavement up. And while it weighs 500 pounds more than the gasoline version, it offers virtually all the amenities, performance and manipulation of its fossil-fuel counterpart. In 1995, Toyota placed 20 prototype RAV4-EVs in the field, ten in Japan and ten in the US. These were a mixture of lead-acid and plate metal hydride stamp battery versions that saw service in LA, San Francisco, Sacramento, Detroit and New York.The lessons acquire from these field ravels have been integrated into the 1998 mystify, including improved HVAC system, battery management and cooling systems, 5 door, 5 passenger seating, improved motor torque and lengthened wheelbase for a better highway ride. The heart of the EV exercise is its 50kW permanent magnet motor and 24 nickel metal hydride batteries rated at 288 volts. The maintenance-free electric motor is neatly integrated into the single speed, front-wheel transaxle and is rated at 67 bhp at between 3,100 and 4,600 rmp. This gives the 3440 lbs. vehicle a combined city/highway private road footslog of 125 miles and a top speed of 78 mph.According to Armstock, these are real world numbers and not just wishful thinking. One of the advantages of using the SUV platform is battery placement. The high curb-height let Toyota engineers place the 900 lbs of batteries chthonic the floorboard, away(p) the passenger cabin. This gives the vehicle the same usable space as its IC-engine version. One of the lessons learned from the tests in the US, curiously in Michigan and New York was the necessity of an capable change and cooling system. HVAC systems in automobiles have enormous energy requirements which cut into the range of an EV, even one equipped with advanced batteries.Toyota engineered two new features to manoeuver this need. They introduced a new gas-injection heat pump system to handling both heating and air conditioning. They excessively installed controls which will preheat or pre-cool the vehicle while its being recharged. The vehicle operator sets an onboard timer whic h begins heating or cooling the SUV while it is still connected to its charging source. Since it takes several minutes for a conventional car to heat up in the winter or for the AC to become effective in the summer, the RAV4-EVs system offers a distinct advantage.Charging is accomplished by an on-board 220-volt, 30-amp conductive charger that takes about 6. 5 hours to in all recharge the car. Refueling the vehicle can be done at home, the workplace or humanity charging station. The RAV4-EV has power-assisted 4-wheel, anti-lock (ABS) braking. The system features 10 inch halt (front disk/rear drum) instead of the usual 9 inch found on the gasoline model to handle the vehicles added weight. It also includes regenerative braking which converts much of the vehicles forward motion back into electricity to recharge the batteries while driving.As the vehicle slows or the driver taps the brake, the electric motor switches to generator-mode. This enables the driver to actually add to the RAV4-EVs range with intelligent driving practices. The hallmark of the legitimate boom in Ute sales is the plethora of amenities that come on these brutes, and the RAV4-EV is no slacker in this regard. It comes equipped with power-steering, deluxe AM/FM stereo cassette speech sound system, digital clock, power-windows, rear-window defroster, dual airbags, vanity-mirrors, and all the rest.The RAV4-EV is currently visible(prenominal) only in California, New York and Massachusetts, due generally to their ZEV mandates which require companies like Toyota have 2% of their sales be zero emission vehicles, this despite the fact that there was (as of December, 1997) only one public charging station in all of New York state. Armstock explained that Toyotas current marketing efforts are focused on languish operations, rather than the consumer market electric utility companies being the earliest customers. They lease for a one-time payment of $16,000 for 36 months, or $477 a month for th e same period.I found the RAV4-EV a thoroughly enjoyable driving experience the brief time I was bottom the wheel. It handles well, accelerating as briskly as a 4 cylinder IC-engine version. Its quiet inside, though the low rolling-resistance tires are a bit noisy. It certainly brakes well as I learned when an yawning(prenominal) driver tried to pull out in front us during our test drive almost Disney World. The RAV4-EV will make an ideal intra-city commuter for many motorists. Since the average American workplace commute is under 50 miles round trip, the RAV4-EV can get you there and back again with style and comfort.Toyotas Armstock do an interesting comment near the end of our test drive. When asked when we can expect to see the RAV4-EV go on sale to consumers, he remarked that the technology is advancing so rapidly that he expects the current model to be as obsolete in thee years as a pesonal computer with an Intel 286 micro-processor is today. Thats an exciting prospect, co nsidering how well integrated the RAV4-EV is even now. Regardless of the pace of technical change, this is one nicely done SUV, one that makes a lot of sense right now, especially now. break off STORY/
