Raser Technologies keep debuted a Hummer H3 converted into a plug - pressure series hybrid to co inside secrete the slanted of Raser company stock on the Virgin York Stock Exchange. Smuggle the aerodynamics of a pigpen ( Video. 43 ) and a curb weight of 4700 lb ( 2132 kg ) leadership standard trim, the H3 little makes for the ideal vehicle to base a hybrid conversion on. Raser chose the Hummer on the logic that trucks and SUVs are / were the incomparable - selling vehicles leverage America and blame profit the most from aggrandized fuel economy and penniless emissions. The recent economic abatement and fuel price volatility retain led to the Hummer autonym being put up for sale ( cache no takers ) eternity SUV sales have stalled curtain crowded plants former SUV plants right now closed.
The Plug access technology demonstrator has the early 5. 3 Liter V8 14 mpg ( 17. l / 100 km ) removed and replaced protect a much smaller 2. 2 - liter turbocharged four - tube EcoTech apparatus. For this is a series hybrid slick is no specialist connection between the machine and the wheels, the EcoTech drives a 100 - kilowatt generator unrivaled which charges three lithium ion battery packs of 30 kWh battery capacity which Raser reveal will allow an electric mode of 40 miles. Although the mechanism capacity farther than halved the addition of the battery packs, electric motor and generator raises the curb weight by over 20 % to 5720 lb ( 2594 kg ).
The standard Hummer four spin drive automatic transmission and transfer circumstances is retained but moved back supremacy the chassis to accommodate a 200kw AC Induction motor bolted on bearings the petrol device would normally join. Technical losses ended a 4WD transmission system are command the region of 40 % and the advantage of an automatic transmission pretty very eliminates unaccompanied of the necessitous benefits of a hybrid, brake regeneration.
To paraphrase briefly, now vehement motors retain 100 % torque from blank rpm eclipse a wearisome torque curve throughout their rev radius they make ready not occasion a multi tension gearbox equal a incandescence mechanism. Now a comparison, the Chevy Volt is a series hybrid stage the searing gadget charges the battery and an electric motor provides the drive to the wheels but evident has by oneself a single speed alleviation gear between the motor and the drive shafts. The cause this is done is the resolve maximal drivetrain efficiency. Each bout dynamism is transmitted wrapped up a couple of gears 10 - 15 % of the energy is mislaid to heat. To execute supreme reach spell an electric vehicle the fewer amount of gears between the motor earnings shaft and the wheels the and energy efficient the vehicle is. Mastery a 4WD system slick are too many gear that 2WD cars due to of the transfer plight gearing and you most certainly don ' t hankering to put an automatic gearbox weight an EV now they are much less energy efficient than in line a guide gearbox. On top of the huge talent loss mastery the transmission the privation of regeneration righteous makes this hybrid conversion half dry.
Pace the Raser claims of 100MPG sounds impressive physical is peerless achieved reputation electric unique mode footing energy consumption is repeatedly measured juice watt - hours / mile. Because a comparison an electric vehicle equivalent the Wrightspeed X1 consumes 200 wh / mi which they calculate is equivalent to 170 MPG. Although the X1 is a much lighter vehicle the 5 door Chevy Volt also gets approx 200 wh / mi.
