A hybrid electric vehicle (HEV) brings together a traditional internal combustion engine (ICE) with the electric powered propulsion system. The presence of the electrical powertrain is supposed to accomplish possibly far better fuel economy when compared to a standard vehicle, as well as superior performance.

A variety of kinds of HEV exist, and also the degree to which they perform as EVs may differ also. The most common type of HEV is the hybrid electric powered car, although hybrid electric vans (pick-ups as well as tractors) also exist.

Current Hybrid Electric Vechicles or HEVs take advantage of efficiency-improving engineering for example regenerative braking, that converts the vehicle's kinetic energy into battery-replenishing electric power, as opposed to wasting it as heat energy since standard brakes do. Some varieties of HEVs work with their internal combustion engine to generate electricity simply by spinning a power generator (this kind of blend is termed a motor-generator), to be able to choose to recharge the batteries or directly power the electrical drive motors. A lot of HEVs reduce idle pollutants by closing down the ICE at idle and then restarting it when needed; this method is recognized as a start-stop system. A hybrid-electric creates less pollutants from its ICE than a comparably-sized gasoline vehicle, being an HEV's gasoline engine is usually small compared to a pure fossil-fuel vehicle, and if not utilized to directly drive the vehicle, can be geared to operate at greatest effectiveness, further improving gas mileage.

Ferdinand Porsche in 1900 designed the Lohner-Porsche Mixte Hybrid, the earliest gasoline-electric hybrid vehicle in the world.

This detector is powered by using the batteries which you should replace every three weeks. You will get the safety that is provided by the Whistler XTR-540 radar detector for your driving in the more convenience way. However, the detectors still have the weakness which is less range in detecting the POP radar signals.

Since the detectors are operated by using the batteries, the detectors will turn on and off automatically. This setting is given by the save energy unit in order to save the battery power. Due to this, the detector works less efficient.

Before buying any radar detector for your vehicles, it is advisable for you to check the state rules or laws for the radar detector. The laws will also set use of radar detector. In many cities or states, the radar detector is allowed for the non commercial vehicles only. But in some places like the Washington, D.C. or Virginia, it is not acceptable.

Whistler Company provides you three AA Ni-MH batteries which you can charge when they are drained. You can also plug the detector to the vehicle's cigarette lighter adapter which will recharge the batteries. After you charge the batteries, they are able to power the detector for 15 hours. You can watch the progress of your radar detector like the signal detected, signal strength, and modes of operation indicator in the blue LCD text display.

This radar detector has the patented POP mode detection. It will send the warning if it detects any crucial condition. The warning is sent through the audio alerts. It does not only offer you the audio but also visual warning. The visual warning is provided by the low profile alert periscopes. You will be warned by two extra LED flash that will on and off. Additional features which you get from this detector are three city modes/highway modes. The highway mode will give you the full audio and the visual warning of the radar systems while keeping the complete sensitivity. This setting is the default setting of the detector.

Meanwhile, the city mode will reduce the annoyance that is caused by the automatic door openers and burglar alarm alerts. It will remain quiet unless the signal strength becomes strong. When the changing of the signal strength happens, the unit gives the brief alert in order to notify you.
