Automotive Trucks information on net.

In 2003, giant SUVs and pickup trucks, most of which function a large part of the time as family transportation, posted new sales records. Automakers provided buyers of these vehicles with sufficient incentives to ensure strong demand even as the number of name-plates and capacity devoted to them expanded.

At the Detroit auto show, the Japanese showed off their newest entries and concept vehicles, which declared their full participation in these profitable segments.

With so many new models and so much more capacity, dedicated to light trucks, it is easy to forecast declining margins in the sector. However, it might be appropriate to question the underlying assumption that the heaviest and biggest of the light trucks will continue to maintain even current sales.

Today's SUV owner has better looking and better driving alternatives to the unglamorous and ungainly tanks that are rapidly losing their fashion edginess. No longer are SUVs a fashion statement that suits the country club lifestyle. They are everywhere and they are not fun to drive. They merely let you haul a lot of people and stuff, so I'm not sure what that says about these owners versus the driver of a new Porsche Cayenne or Volvo SUV.

Fuel economy may not be on the auto industry's radar screen but it should be. The high price of gasoline and the fact that rising global consumption well keep the pressure on crude oil prices as China develops a car culture means that the days of $.90 a gallon gasoline are permanently over. Even though U.S. gasoline is still cheap by international standards, it is taking a bigger bite out of budgets.

Finally, the justification of driving an SUV on the basis of safety is open to question. It is a fact that these heavy vehicles cause more damage to smaller lighter vehicles, but SUV owners assumed they got more protection even as they made roads more dangerous for others.

Recently I witnessed an accident in a parking lot where the driver of a giant SUV backed into a Honda Accord pulling into the lot and pressed the car into the wall of a restaurant crushing the driver's side door. The SUV driver explained to police that she didn't see the Honda and she apparently wasn't aware she hit a car until onlookers began shouting.

In a technical paper delivered Nov. 14, 2001 at the SAE Truck & Bus Show in Chicago, Delphi said its Delphi's 42-Volt Energen-10 integrated starter-generator (ISG) has demonstrated significant fuel savings.

The paper details the fuel economy gain provided by a 42-Volt system for engine stop-start functionality, as implemented by Delphi in a sport utility vehicle. The study reports prototype vehicle results, consistent with vehicle simulation models that show fuel savings to be as much as 4 to 6 over the Federal Test Procedure-75 (FTP-75) driving schedule from stop-start functionality alone.

"The impact the 42-Volt ISG system has when activating all functions beyond that of the stop-start function is tremendous," said R. Scott Bailey, director of engineering, Delphi Energy & Chassis Systems. "Fuel economy improvements of 10 to 15 percent on the FTP-75 driving cycle are achievable and have been established both in simulation and in prototype vehicle testing."

Reduction in fuel consumption is achieved through the ISG's use of functions such as engine-off during cost-down and idle, early torque converter lockup with torque smoothing, deceleration fuel cutoff, regenerative braking and electrical launch assist, Delphi said. It also boosts the onboard power generation and energy storage, allowing for increased vehicle electrical loads.

"These same functions can yield 2 to 3 times the fuel economy improvement in commercial heavy- and medium-duty pick-up and delivery vehicles due to the stop and go nature of their drive-cycle," added Gary A. Cameron, chief engineer, Energenix Center, Delphi Energy & Chassis Systems.

The Energen-10 ISG system also monitors and notifies the driver of any issues with battery life, the company said.

"Delphi has simulation capabilities that can be utilized on complex products like the Energen-10 ISG system," said Cameron. "Using this valuable approach, our engineers can determine an optimized product solution for the customer."
