Boosterjet Technology

Getting more from less

As the small car experts, making the most of precious resources and reducing pressure on the environment has always come naturally to Suzuki. Over the years while cumbersome ‘gas guzzlers’ came and went, Suzuki concentrated on smaller, lighter, more efficient vehicles that were fun to drive while never compromising on performance.

With BOOSTERJET technology, Suzuki’s new generation of engines use cutting-edge technology, engineering and materials to deliver the power, torque, and feisty feel you would expect from an engine twice it's size. From SUVs to hot hatchbacks, this advanced turbo engine technology consumes less fuel and has lower emissions – so how on earth is this possible?

Direct injection

By directly injecting the optimum amount of fuel into the cylinders BoosterJet engines optimise combustion and thus reduce fuel consumption. Six-hole injector nozzles and a high-pressure pump quickly create the ideal air-fuel mixture inside the cylinder. Even the shape of the intake ports and the pistons themselves have been designed to generate a stronger tumble flow, ensuring cleaner, more stable combustion.


If an engine can burn a greater amount of fuel-air mixture in a given time, output can be raised without increasing size or displacement. To achieve this, BoosterJet engines have a turbocharger which utilizes the energy of the exhaust gases to drive turbines and force-feed compressed air into the cylinders. You’ll immediately feel the difference with more torque available, even at lower revs.

Waste gate

This special valve controls boost pressure in order to prioritise either fuel efficiency or dynamic performance depending on the driving situation. Round town the waste gate opens for more fuel-efficient driving. Then, when you need acceleration, the valve closes to increase boost pressure delivering instant performance and power.

Lightweight and compact

The BoosterJet’s highly sophisticated design is smaller and lighter than an ordinary engine. This not only adds to its efficiency, but also to the vehicle’s overall performance and handling. As a bonus, it also makes room for other things – like more storage, bigger boots, and increased legroom. Combined with lighter, stronger platforms, BoosterJet engine technology is a game-changer.
