A hybrid powertrain combines an internal combustion or engine with electric adds several design to vehicle manufacturers and several components to the vehicle. From estimates, the electrical/electronic content in the will almost double if the is a hybrid, especially in the near with low volumes. The key added of the hybrid include an electric inverter, dc-dc converter, electronics and high-voltage batteries. has indicated that the price of the Escape Hybrid will be more than a comparably V-6 (only) powered Escape

GM’s Silverado 42 V mild cost $1500 more


Expected sales of U.S. hybrid vehicles in are approximately 36,000 Honda and 47,000 Toyota Prius the Honda Insight dropping to a 1,000 or so units. The addition of Hybrid Escape with annual sales of 20,000 (4,000 units in 2004), Silverado and Sierra models for 2,500 units in MY2005) and Chrysler’s diesel electric Ram scheduled for 100 units will hybrid numbers slightly However, with sales of 16 total cars and light expected in 2004, this hybrids are quite a bit less 1% of the market — but it’s a start.

In spite of record high prices in 2004, the additional cost of the fuel-efficient hybrid still mean a payback of two to three years to offset the purchase price. In contrast, appear to be more than to pay an additional $895 for a Dodge with a 345 hp, 5.7-liter hemi over the 230 hp, 4.7-liter engine. To raise the cost impact of purchase, drivers often in a perfectly good low-mileage, vehicle to get the additional performance, them an additional $7000 to in depreciation [2].

Hybrids have the potential to fuel economy, performance and emissions. Automotive power designers have options on the type of vehicle they to produce. For highest fuel the engine and electric motor are at optimal points to achieve efficiency. The internal combustion (ICE) has average efficiencies of 15% but can 30% when operating in the sweet For performance, different points in the and horsepower curves between the and engine are exploited.

This can provide more torque with increased economy.

The Accord hybrid will go into production in provides an example of the change in design. It uses the Integrated Assist (IMA) hybrid concept from the Insight and but will provide V-6 performance 4-cylinder economy. Honda did not the engine size when it the electric motor to the drive A summary of vehicles and their increase using electric is shown in Table 1. Using values, the Honda Insight’s and Toyota’s 2002 Prius at hplb are more like the of vehicles sold in the early limiting the number of people who be interested in purchasing such for lack of performance. For comparison, a Camry 6 cylinder is 0.062 and F-150 5.4L V-8 is 0.061

When vehicles exceed hp/lb they appeal to than 50% of the buyers, and those are frequently willing to pay more for performance, as indicated in Figure 1
