The Family 0 is a family of inline piston engines that was developed by GM-Opel Powertrain, a subsidiary of Adam Opel GmbH, as a low-displacement engine for use on entry-level subcompact cars from Opel.

The engine was first introduced in 1996 Opel Corsa as a 3-cylinder version. It features light cast-iron engine block, aluminum cylinder head with hollow-cast camshafts and DOHC valvetrains driven by chain. Modern versions use variable intake technology.

1.0 L Straight-3 (973 cc): 40 kW / 55 hp, 82 N⋅m (60 lb⋅ft) @ 2800 rpm
1.0 L Straight-3 (973 cc): 43 kW / 58 hp, 85 N⋅m (63 lb⋅ft)
1.0 L Straight-3 (998 cc): 73.4 mm (2.89 in) bore, 78.6 mm (2.94 in) stroke, 10.5:1 compression.
1.2 L Straight-4 (1199 cc): 72.5 mm (2.85 in) bore, 72.6 mm (2.86 in) stroke, 10.1:1 compression, 75 hp (55 kW) @ 5600 rpm, 110 N⋅m (81 lb⋅ft) @ 4000 rpm
1.2 L Straight-4 (1229 cc): 73.4 mm (2.89 in) bore, 72.6 mm (2.86 in) stroke, 10.5:1 compression

TwinPort

New, updated version of the engine, introduced in 2003. Features TwinPort technology - twin intake ports with a choke closing one of the ports at low RPM, providing strong air swirl pattern for higher torque levels and better fuel economy.

1.0 L Straight-3 (998 cc): 73.4 mm (2.89 in) bore, 78.6 mm (2.94 in) stroke, 10.5:1 compression, 60 hp (44 kW) @ 5600 rpm, 65 ft.lbf (88 Nm) @ 3800 rpm.
1.2 L Straight-4 (1229 cc): 73.4 mm (2.89 in) bore, 72.6 mm (2.86 in) stroke, 10.5:1 compression, 80 hp (59 kW) @ 5600 rpm, 81 ft.lbf (110 Nm) @ 4000 rpm.
1.4 L Straight-4 (1364 cc): 73.4 mm (2.89 in) bore, 80.6 mm (3.2 in) stroke, 10.5:1 compression, 90 hp (66 kW) @ 5600 rpm, 125 N⋅m (92 lb⋅ft) @ 4000 rpm.

TwinPort engines are used in:

Future vehicles:

2011 Chevrolet Volt

EcoFLEX

The EcoFlex engine is a version of the TwinPort tuned to provide better fuel economy and lower emissions.

1.4 L Straight-4 (1398 cc): 73.4 mm (2.89 in) bore, 82.6 mm (3.3 in) stroke, 10.5:1 compression, 130 N⋅m (96 lb⋅ft) @ 4000 rpm, 87 hp (65 kW) @ 5600 rpm or 100 hp (75 kW)) @ 6000 rpm

The EcoFlex engine is used in:

Opel Corsa EcoFLEX
Opel Astra EcoFLEX

Turbo

Opel and US-market Chevrolet versions of the Delta II platform compact cars will feature turbocharged version of the 1.4 L engine with of variable valve timing, and optional gasoline direct injection.^[1]^[2] This small turbocharged engine will deliver the performance of much larger naturally-aspirated engines while maintaining fuel efficiency of a small engine. Expected Highway fuel economy is more than 40 mpg.^{[clarification needed]}

1.4 L Straight-4 (1364 cc): 72.5 mm (2.85 in) bore, 80.6 mm (3.2 in) stroke, 9.5:1 compression, 140 hp (103 kW) @ 4900 rpm, 200 N⋅m (150 lb⋅ft) @ 1850-4900 rpm.

The engine will be used in:

2010 Opel Astra
2011 Chevrolet Cruze

HCCI

The direct injection version of 1.4 L VVT Turbo engine will be able operate in ignition-less HCCI (Homogenous Charge Compression Ignition) mode ^[3]^[4] when equipped with two-step adjustable valve lift with variable cam phasing and advanced ECU with cylinder pressure sensors. 6.8–8 km/litre in the city(over 800 km). 9–12 km/lite on the highway (over 800 km).
