Right now there are four big issues that are generating change in the development of future transportation, says Technical Editor, Jim Kerr who discusses how these issues are affecting the cars we will drive in the future.

Auto Tech: Oils that save fuel

Chris — Wed, 21 Jul 2010 08:02:43 +0000

Lighter viscosity engine oil, such as 0W-20 synthetic engine oil, is being specified by many vehicle manufacturers as a way of reducing fuel consumption, reports Technical Editor, Jim Kerr. How? "Reduced internal engine friction...improves fuel economy," he says.

Auto Tech: Atkinson Cycle engines and Hybrids

Chris — Wed, 14 Jul 2010 08:02:20 +0000

Atkinson Cycle engines offer better fuel economy than Otto Cycle engines, but reduced low-speed torque. However, when combined with hybrids’ electric motors which have excellent torque, they work well, says Technical Editor, Jim Kerr.

Auto Tech: Noisy mufflers

"Do mufflers have to be noisy to perform? No. Can aftermarket systems be quiet? Yes, if selected properly," says Technical Editor, Jim Kerr who explains how mufflers work.

Auto Tech: How to recognize mechanical problems early

Chris — Wed, 23 Jun 2010 08:02:02 +0000

The only thing that Ford’s new 6.7-litre Power Stroke V8 turbocharged diesel engine shares with the previous SuperDuty diesel is the name: everything else is new, reports Technical Editor, Jim Kerr.

Auto Tech: Variable valve timing

Chris — Wed, 16 Jun 2010 08:02:03 +0000

Variable valve timing on the intake and exhaust valves improves fuel economy and engine performance and lowers emissions, says Technical Editor, Jim Kerr. "It is one of those technologies I would look for if I were buying a new vehicle."

Auto Tech: Wheel alignments

Chris — Wed, 09 Jun 2010 08:02:56 +0000

"Getting a wheel alignment should be part of your annual maintenance schedule," advises Technical Editor, Jim Kerr. "An alignment can detect problems before they become serious or unsafe. It can also increase tire life and fuel economy."

Auto Tech: Servicing wheel bearings

Chris — Wed, 02 Jun 2010 08:02:33 +0000

Most vehicles today use sealed wheel bearings, but some, including trailers, need wheel bearings serviced regularly. "Bearings don't fail often, but when they do they can cause a lot of other damage," says Technical Editor, Jim Kerr.

Auto Tech: Aftermarket sound systems

Chris — Wed, 26 May 2010 08:01:54 +0000

Selecting a good sounding aftermarket sound system is more than just selecting components, says Technical Editor, Jim Kerr. The components must compliment each other and be installed correctly, he says.
