Honda Europe recently announced that the 10th-generation Civic for the continent will feature the company’s all-new 1.0 and 1.5 litre VTEC Turbo engines. This time round, more details about Honda’s turbocharged powerplants have surfaced and we’re bringing them to you.

Starting with the smallest offering, the liquid-cooled 1.0 litre three-cylinder turbocharged VTEC engine produces 127 hp and 200 Nm of torque, which is 12 hp less than the R18Z1 1.8 litre naturally-aspirated engine it replaces, but generates 26 Nm more torque (15% increase). In this instance, the engine is powering a test mule in the shape of a European Civic hatchback you see here.

For now, most of the performance figures are estimates, including a century sprint time of 9.5 seconds and a top speed of 209 km/h. The same is said about how green the engine is, with an estimated fuel economy of 28.06 km per litre (a 20% improvement over the 1.8 litre unit, following the NEDC mode), while CO2 emissions stand at 99 g/km when mated to a six-speed manual gearbox.

The engine itself is of an all-new design, with aluminium being the main material used in its construction, no doubt an effort to reduce weight. Direct injection is also present in the DOHC engine, as is dual Variable Valve Timing Control (VTC) and Variable Valve Timing and Lift Electronic Control (VTEC) on the intake side. An oil coated timing belt is also used here as well.

Other features include a high-tumble intake port, high efficiency cooling cylinder head, piston with cooling gallery, sodium filled exhaust valve, and a variable capacity oil pump. For fuel economy purposes, an idling stop system is installed as well.

Moving on to the larger 1.5 litre mill, where it is identical to the engine offered on the US market Civic. In terms of technologies, the liquid-cooled 1.5 litre in-line four-cylinder turbo engine shares a lot in common with the above-mentioned 1.0 litre unit. However, there are a few notable differences starting with a higher compression ratio of 10.6:1.

A larger area of concern is the absence of VTEC on either the intake or exhaust side of the engine, the same as that found on the US market Civic. A more obvious difference is the higher power output, in this case, 201 hp and 260 Nm of torque. Fuel economy for the 1.5 litre engine sees a 15% improvement over the 1.8 litre unit, following the NEDC mode of testing.

Keep in mind that the 10th-generation Honda Civic will only be launched in early 2017 in Europe, and the engine’s final specification might change by then. It remains to be seen if the Malaysian model would adopt the US Civic’s 2.0 i-VTEC and 1.5 litre turbo engine options, or the European 1.0 and 1.5 litre VTEC Turbo units that were recently announced.
