Features of the GMC Hybrid Cars
The GMC Hybrid Cars utilize the first two-mode hybrid propulsion system in any full size vehicle in production today. This technology is patented and has helped to improve the fuel mileage of the Yukon and Tahoe full size SUV’s without losing any of their pulling power or size in the interior. The control module of the drive train monitors the power demand and with smooth precision the appropriate operating power mode is engaged.
This is a sure way to go green with a hybrid SUV. The two-mode system is divided to maximize fuel efficiency without the loss of power.
1) Mode 1: This mode is low speed, idle and light power loads. There are actually three different modes within this mode. For the very light power loads, only the electric motor is supplying power. At the appropriate load limit the conventional engine engages and assists the electric motors. And at a heavy power load requirement only the conventional engine is supplying power.
2) Mode 2: This is the mode for which there is a high power load demanded. The full power of the v8 engine is engaged for situations as when passing on the highway, towing a trailer or ascending up an incline.
Other features of this hybrid include the KERS technology. This system utilizes the kinetic energy lost during the braking process and channels it to the battery. The Vortec V8 engine also has a new and improved Active Fuel Management System to optimize use of the fuel. The aerodynamics of the body is also improved to have a better streamlining effect. To monitor all the new systems, there is a hybrid monitor display visible for the driver to use.
The highway fuel economy is relatively unchanged. The big savings is in the city driving with an increase of nearly 30% better fuel mileage. This GMC hybrid is making its move in the full size market.






I’ve been considering a hybrid, but I’m not sure what to look for. So many terms I don’t really understand and I’m a bit concerned about safety when I’m flying down the road too fast. I like the mileage, but will have to learn more before I can choose.
Laney,
You are wise to do your fact checking first. The salesmen will tell you what ever they want you to know. Better to arm yourself with some good questions before hand. Check out some of the hybrid forums because you will get both sides of the story then.
Myself, I think they are great and if they cost a little more, so what. Any time we can be less dependay on fossil fuels, that is a win-win in my opinion.
Thanks for the comment.
