Today, our contest of champions thrusts two major fuel sources into the spotlight. In this refined hydrocarbons battle, the pros and cons of VW diesel vs. gas engines will be arbitrated so that fuel-conscious drivers can judge for themselves which engines and which pumps are a match for their vehicle needs. Of course, gas engines still rule petrol stations, but modern clean diesel substitutes are no longer playing catch-up with high-octane gasoline, not when Volkswagen engineers get their way.
When Diesel Grew of Age
Older drivers think fondly of gas-guzzling motors, the yesteryear cars that seemed to orbit petrol stations because of their huge tanks and thirsty appetites. Diesel was a less finessed fuel then, probably because it carried impurities and grew waxy when the weather turned cold. Happily, VW diesel engines use a proprietary injection process, so they burn clean diesel more efficiently than their petrol-fueled counterparts. Additionally, Volkswagen’s turbocharged injection technology satisfies contemporary emissions regulations, including Australia’s own low sulfur guidelines, as proposed over a decade ago by the Australian National Fuels Quality Standards Act (environment.gov.au). On this more than fortuitous occasion, engine design and fuel pump output have dovetailed to keep the environment clean and the newest Volkswagen cars fuel economical.
The Pros and Cons
Popularity is a bit of a duel-edged sword, which is why petrol is always in the news. This dominant fuel is lasting longer thanks to better engine designs, but diesel is still regarded as the economical choice when it comes to savings at the pump. Provisionally, diesel is the preferred high-torque solution, so it’s almost always found in the transportation industry. Big eighteen-wheel rigs are powered almost exclusively by huge diesel power plants, but the benefits of this economical power source are now being channeled into smaller vehicles.
Fueling Cars and Trucks
Gasoline or petrol was once considered the ideal match for cars and small trucks. Meanwhile, diesel was used in large trucks, fire engines, and any other vehicle that demanded torque. VW diesel has leveled the playing field by incorporating innovative engine subsystems that blur the lines between torque and velocity, thus positioning diesel as the fuel economy and performance champion.
Volkswagen manufactures more diesel vehicles than anyone else, so the technology driving these systems is guaranteed to be mature and refined. Likewise, the fuel stuff is free of the contaminants that once shortened the lifespans of fine engines. Current environmental legislature is responsible for the latter boon in diesel productivity, but manufacturer adeptness is constantly tweaking TDI engines to match this pump-driven momentum, especially since usable quantities of biodiesel are now on the technology horizon.
