How much horsepower does a Lacetti 1.8 have?
The Lacetti 1.8 typically develops about 122 horsepower (around 90 kW), with minor variations depending on market and model year.
The Lacetti, initially developed by Daewoo and later sold under the Chevrolet banner in many regions, uses a 1.8-liter four-cylinder engine that belongs to GM’s Ecotec/Family 1 family. While 122 PS is the commonly cited specification, exact figures can vary due to emissions tuning, exhaust configuration, and regional requirements. For most owners and buyers, the 122 PS figure remains a reliable reference point.
Engine design and typical output
The Lacetti’s 1.8-liter unit is a straightforward four-cylinder; in standard specification it delivers around 122 PS (approximately 90 kW) with peak torque in the mid- to high-150s Newton-meters range. Power tends to peak somewhere in the 5,800–6,000 rpm band, while torque is available earlier in the rev range to aid everyday drivability.
Variations by market and model year
Across different markets and production years, power figures can show small differences due to regional tuning, exhaust setups, and regulatory requirements. While the widely cited figure is 122 PS, some regional literature and early-spec vehicles have listed marginally higher or lower outputs. If you need an exact number for a specific car, check the vehicle’s build sheet, door jamb label, or the official GM/Chevrolet documentation for that VIN.
Impact on driving characteristics
Horsepower is only one aspect of the vehicle’s performance. The Lacetti 1.8’s torque characteristics—delivered at relatively modest RPM—help with everyday acceleration and highway merging, contributing to a balance between usable performance and reasonable fuel economy for a compact family car.
Summary: The Lacetti 1.8 typically delivers about 122 horsepower (roughly 90 kW), with torque around 165–167 Nm. Exact numbers can vary slightly by market and year.
