Adam to Be First With New Opel 1.0L 3-Cyl.

The powerplant delivers 115 hp and 122 lb.-ft. of peak torque all the way from 1,800 to 4,700 rpm, generating more torque throughout its operating range than equally powerful, higher-displacement engines, the auto maker says.

VIENNA – Adam Opel’s all-new 1.0L turbocharged Ecotec gasoline 3-cyl. engine, dubbed 1.0 SIDI Turbo (Spark Ignition Direct Injection), will take its public bow at the Frankfurt auto show next month.

The powerplant delivers 115 hp and 122 lb.-ft. (166 Nm) of peak torque all the way from 1,800 to 4,700 rpm, generating more torque throughout its operating range than equally powerful, higher-displacement engines, the auto maker says.

Fuel efficiency is improved 20% compared with Opel’s current 1.6L naturally aspirated 4-cyl.

The Opel Adam small car will be the first with the new engine, which will debut next year accompanied by an all-new 6-speed gearbox.

The 12-valve, 1.0L turbo represents the first in a new, modular family of 3- and 4-cyl. gasoline engines that will range in displacement up to 1.6L.

Direct injection, continuously variable valve timing and a lightweight, high-pressure die-cast aluminium cylinder block are key efficiency enablers in the new powerplant, which will be built at Opel’s Szentgotthard, Hungary, engine plant.

The auto maker expects carbon-dioxide emissions to be significantly lower than 100 g/km with each of the family’s new engines.

“In developing this small engine, we not only set out to minimize fuel consumption and CO2 emissions, we also wanted to demonstrate that three cylinders can be just as refined as four or more,” Matthias Alt, chief engineer-small gasoline engines, says in a prepared statement.

“We tackled at source the balance, noise and vibration issues typical of conventional 3-cyl. engines, and we’re confident customers will be pleasantly surprised by the results,” Alt adds. “This is a very lively and refined 3-cyl. engine which doesn’t compromise on driving fun.”

Refinement is maximized through inclusion of a balance shaft and high-pressure fuel injectors that are structurally isolated from the cylinder head to minimize noise and vibration.

Other noise-reduction measures include acoustically optimized covers for the top and front of the engine, the intake manifold and camshaft housings; crankshaft isolation with iron main bearing inserts; inverted teeth for camshaft drive chain; a low-hiss turbo compressor; and a lower oil pan formed from steel.

Opel says the new 6-speed manual transmission is more compact and about 30% lighter than its current gearbox and will work with engines producing up to 162 lb.-ft. (220 Nm) in peak torque.
