On drive cycles representing routes with fewer stops and accelerations, the gHEV trucks demonstrated similar fueleconomy to the diesels. Ah NiMH battery pack. Click to enlarge.
Fueleconomy was similar between the gHEVs and diesel vehicles, except for the highest kinetic intensity drive cycle where the hybrid exhibited ~20% higher fueleconomy. NREL collected and analyzed data for in-use fueleconomy and fuel costs, maintenance costs, total operating costs, and vehicle uptime.
Lexus’s 2013 GS 450h—the new generation hybrid version of the GS 350, introduced at the 2011 Frankfurt Motor Show ( earlier post )— offers EPA-estimated fueleconomy ratings of 29 mpg US city, 34 mpg US highway and 31 mpg US combined (7.7, L/100km, respectively). Total system output is 338 hp (252 kW).
Not only is friction loss reduced, coolant flow rate can be very precisely controlled, contributing to improved fueleconomy. The NiMH hybrid battery is placed under the rear seat for more efficient use of interior space. The water pump is driven by an electric motor, thus eliminating the need for a drive belt.

seconds; its EPA estimated fueleconomy rating is 42 mpg US (5.6 Together, these technologies minimize situations when fuel enrichment is necessary to protect the catalytic converter from overheating damage, thereby improving fueleconomy and lowering emissions. The CT 200h’s hybrid system features a 1.8-liter,
It shuts off engine power smoothly when the car is stopped and seamlessly restarts as the driver releases the brake pedal, helping Fusion to reduce fuel consumption and emissions by approximately 3.5%. This powertrain is anticipated to deliver best-in-class fueleconomy of 47 mpg (5.0L/100km)
Pike suggests that North America will experience a rebound in a few years, as the economy stabilizes along with public transit funding levels. activity, although China is not pushing as aggressively in fuel cell as with battery electric buses. Fundamentally, all of these buses require either government emissions or fueleconomy policy.

Traditionally, maximizing fueleconomy and minimizing GHG emissions are the main objectives of the control development. Although for the paper they worked with a NiMH battery system, the analysis can be easily extended to a Li-ion battery system.
The NiMH battery pack is located under the rear cargo area within the wheelbase for optimized balance. The Eco mode adjusts air conditioning settings and the throttle for the best possible fueleconomy. The engine-driven generator can charge the battery pack or provide additional power to the drive motor as needed.

The next Prius will feature improved batteries with higher energy density.
As a result, government incentives and emissions or fueleconomy regulations will continue to play a very important role in promoting hybrids and plug-in trucks. Pike Research’s analysis further indicates that most HEV, PHEV, and BEV trucks will utilize different chemistries of lithium-ion (Li-ion) batteries.
liter gasoline engine that reaps the performance and fueleconomy benefits of high thermal efficiency; and a new mid-power, fourth-generation self-charging hybrid system. The powertrain development program focused not just on outstanding fueleconomy, but also on a high level of driving appeal. UX 200 with new 2.0-liter
However, research suggests that most consumers have little experience or understanding of electric drive, and have difficulty quantifying their valuation of fueleconomy. They note that other requirements may make NiMH unsuitable for PHEV applications. Axsen et al.

This experience has convinced Toyota of three things, he said: NiMH batteries appear to be the best choice for conventional hybrid vehicles for some time to come. A recent test with a Highlander Fuel Cell Vehicle achieved a range of 431 miles on a single fill of compressed hydrogen, representing fuel consumption of 68.2
Asked why not Nickel Metal Hydride batteries in the Volt, at least to start, he says "NiMH just doesn't do it." Interestingly, Lutz says GM is being approached by NiMH manufacturers to use this proven battery chemistry in the Volt. And if Lithium proves problematic, he says GM will again consider NiMH. But hold on.
Environmental impacts will be assessed through both fuel use and also emissions testing in a controlled-environment test. Designline Ecosaver IV hybrid propulsion system (2 units); power 120 kW (160 hp) continuous, 190 kW (253 hp) peak.
