LPG + Toyota Hybrid Drive = Tri-Fuel Hybrid Marvel

It was just logical. 

You would take the best automotive technology hybrid drive and marry it with the cleanest and most economical commercial fuel LPG.

That’s just what Orbital Autogas did and the results are nothing short of stunning. 

Hybrid LPG is the new benchmark in fuel economy.

Birth of the Tri-Fuel Revolution

The Toyota Camry Hybrid, with its petrol-electric hybrid drive, is already one of the most economical cars on the market. 

But the engineers at Orbital were convinced that they could make it even better.

They mated their state-of-the-art LPG liquid injection system with the Camry Hybrid. 

What they developed was an ultra-efficient tri-fuel vehicle that is truly revolutionary.

How does LPG Liquid Injection Work?

LPG Liquid InjectionThe Orbital system pumps LPG at high pressure into the inlet manifold, via a liquid LPG injector. 

The LPG immediately vapourises, which also causing the surrounding air to cool rapidly. 

This rapid cooling increases the air density which, in turn, improves engine efficiency and performance. 

The engine power output is improved, as is low end torque.

The system is controlled by an electronic control unit (ECU) which is a dedicated computer that regulates the various components. 

The ECU works in tandem with the car’s own petrol computer to optimise the injection timing.

Real World Test

The LPG gurus at Orbital decided to conduct a real world test. 

They took six vehicles with engines ranging from 4 to 8 cylinders, including two hybrids, and powered by either petrol, diesel or LPG:Camry Hybrid LPG

  • Ford Territory 2.7L Turbo Diesel

  • Holden Commodore 6.0L LPG

  • Mitsubishi Lancer 2.0L Petrol

  • Ford Falcon 4.0L LPG

  • Toyota Camry Hybrid 2.5L Petrol

  • Toyota Camry Hybrid 2.5L LPG

The day consisted of a 144km drive around Sydney with all six vehicles. 

They started by carefully filling each one with fuel.

Over the next eight hours, there were various driving conditions and numerous driver changes. 

They finished back where they started and refilled the vehicles.

The Results

In what was admittedly not a scientifically controlled test, the Camry Hybrid LPG was the clear winner. 

The cost of fuel was almost 40% less than for the identical petrol powered Camry Hybrid, which came in second best.

The full-size 4.0L Ford Falcon, with Liquid Injection, came in third, trouncing the smaller 4-cylinder petrol powered Lancer. 

The Falcon cost of fuel was 23% less than that for the Lancer.

It was also interesting to note that the 6.0L V8 LPG powered Holden actually had lower fuel costs than the 2.7L Turbo Diesel Territory. 

This is further proof that regardless of the engine displacement, liquid LPG injection works and works well. 

The LPG cars also don't have the issue of carcinogenic diesel exhaust fumes.

Camry Hybrid LPG wins
Individual results may vary based on driving habits, fuel prices and driving conditions.

The Future is Tri-Fuel

LPG fuelled hybrid drive is the way of the future. 

It will appeal equally to cost conscious consumers and profit minded fleet buyers.

Hybrid LPG conversions are available now.
