The 2022 Honda Civic Si HPT pairs a 200-hp turbocharged engine with a six-speed manual, rev-match control and a helical limited-slip differential. HPT’s documented difference from the standard Si is its 235/40R18 high-performance summer tires—not more power. The ’90s JDM comparison is best understood as an enthusiast analogy, not a measured comparison with a specific older car.
Honda’s specifications establish the Si’s equipment and figures, but the available research does not establish first-person road-test results, instrumented performance or a direct comparison with a 1990s model. The overview below sticks to verified U.S.-market specifications.
What does HPT mean on the 2022 Civic Si?

Engine, manual transmission and driver controls
Both Si trims use a 1,498-cc turbocharged inline-four rated at 200 hp at 6,000 rpm and 192 lb-ft from 1,800 to 5,000 rpm. Honda specifies a six-speed manual with rev-match control and a helical limited-slip differential. The HPT designation does not indicate a power increase.
Honda also lists a lightweight single-mass flywheel and a three-mode Normal, Sport and Individual drive system. In the Individual mode, Honda says drivers can select engine response, steering effort and instrument-panel display color parameters. These are manufacturer-described features, not independent findings about how the car feels on the road.

Fuel economy and fuel
Honda’s 2022 feature highlights give EPA ratings of 27 mpg city, 37 mpg highway and 31 mpg combined. Honda lists regular unleaded as required and premium as recommended. These are manufacturer-published specifications, not independently measured results.
Does the HPT make the Si a ’90s JDM experience?
The comparison can work as a description of the enthusiast appeal: a manual transmission, a limited-slip differential and a compact sport-sedan format. But Honda’s specifications do not demonstrate that the 2022 Si drives like a particular 1990s Japanese-market Civic or Integra. The turbocharged engine and contemporary driver-assistance and connectivity equipment also make it a distinctly modern car.

For a buyer choosing between the two U.S. trims, the practical distinction is seasonal tire equipment. The HPT’s summer tires are intended for warm-weather performance use; the standard Si’s all-season tires are a different factory specification. Check the tire maker’s guidance and local conditions when selecting replacement tires. Honda does not identify an original-equipment tire brand in the cited specifications.
