1.5L VTEC TURBO THE TURBO ENGINE WITH EXCEPTIONAL PERFORMANCE AND FUEL ECONOMY
Traditionally, turbo engines are deemed ‘high power, low fuel economy’ but Honda’s VTEC TURBO is an engine that achieves fuel efficiency without compromising the enjoyment and quality of the ride.
1.5L VTEC TURBO
The 1.5L VTEC TURBO combines its turbo charger with a direct injection system and variable valve timing mechanism, retaining all the fuel economy benefits of a small engine. As a result, it produces a feel of power that is smooth from low revs to the high end, exceeding the torque of a 2.4L engine. This keeps acceleration exhilarating on any roads – urban driving to highways and even uphill climbs.
VTEC TURBO FUEL EFFICIENT UNDER ANY CONDITION
The VTEC TURBO engine is fuel efficient regardless of driving conditions – from city driving with frequent stopping and starting, to highway driving. On city drives, a 2.4L naturally-aspirated engine produces high torque because of its displacement. The engine produces more torque than the 2.4L naturally-aspirated engine, thanks to its turbo. On top of that, it also allows a small, 1.5L engine to perform as well as a 2.4L engine.
VTEC TURBO’s 3 Vital Technologies
Honda’s VTEC TURBO realises high fuel economy and exhilarating power through three vital technologies – Dual VTC for Intake and Exhaust, Direct Injection System and High Tumble Intake Port, and Highly-responsive Turbocharger with Electronic Wastegate.

Turbocharger
1. Direct injection system and high tumble intake port
The VTEC TURBO uses direct injection technology to inject fuel directly into the cylinders, lowering the temperature within the cylinders by the gasoline’s vaporisation heat. Thanks to the cooling effect of direct injection and rapid combustion by high tumble flow, fuel is quickly and efficiently burned.

2. Dual VTC for intake and exhaust
With VTEC TURBO, Valve Timing Control (VTC) changes the timing for intake and exhaust valves to operate, controlling the amount of time both types of valves are simultaneously open – this allows efficient supercharging even at low engine revs.

3. Turbocharger with electronic wastegate
‘Turbo lags’ are a typical outcome of conventional turbo engines. Accelerations tend to lag upon accelerating, as exhaust energy must rise to spin the turbines which then increase intake amount. This problem is rectified with the VTEC TURBO – using a turbocharger with electronic wastegates equipped with small-diametre turbines that spin efficiently on small exhaust energy. As a result, the turbo engine is sharp and rapidly responds to how the accelerator pedal is depressed.
