2023 Acura Integra vs.
2023 Honda Civic Si
The mechanically similar 2023 Acura Integra and the 2023 Honda Civic Si are two of the auto industry’s most desirable and budget-friendly performance sedans. While they certainly have a lot in common, the arrival of the newest Integra (which is essentially the more rakish and upscale version of the Civic) has made its old fans happy after a 22-year hiatus. Sure, the Civic Si is also a stalwart with its own following, but Acura really poured its heart into resurrecting the Integra for the modern age, and it shows. We sought to compare these related models for drivers who have a keen interest yet remain undecided on which to choose.

Mechanical Specs
While the Integra and Civic Si have the same heart and soul – a 200-horsepower turbocharged 1.5-liter four-cylinder powerplant – the Integra differs in that it comes with a standard continuously variable transmission (CVT), while a six-speed manual gearbox is available. The Civic Si, on the other hand, is made only with the six-speed stick. Although the manual tranny is the preference of driving purists, most people prefer not to shift themselves – that is, if they ever learned how to.
Fuel Economy
Even though most true driving enthusiasts will show preference for the stick, the CVT-equipped Integra pulls off better fuel economy, achieving an EPA-rated 30 mpg in the city and 37 mpg on the highway with the base trim. The strictly manual Civic Si gets the same fuel economy on the highway, but it only returns 27 mpg in the city.
Premium Amenities and Cargo Space
The Integra is further distinguished from the Civic Si in that it’s offered in three trims: Base, A-Spec, and A-Spec w/Technology. In contrast, the Si comes as a single trim. The Integra’s broader trim selection means access to better features, even if its price tag is a little steeper. For instance, it can be ordered with fog lights, a head-up display, leather upholstery, power-adjustable and heated front seats with driver’s position memory, ambient interior lighting, an auto-dimming rearview mirror, a wireless phone charger, a 16-speaker ELS Studio audio system, two second-row USB-A charging ports, and a 10.2-inch digital gauge cluster. The Integra is also eligible for adaptive dampers and a comfort-enhancing drive mode. Nothing in that list of attractive amenities is available in the Civic Si. Plus, the Integra’s hatchback-style cargo area affords 24.3 cubic feet of total cargo volume, which is 9.9 cubic feet more than the Civic Si has to offer.
Advanced Safety Systems
The Integra and Civic Si are both outfitted with an array of critical driver-assistive technologies (forward collision warning with collision mitigation braking, road departure mitigation, adaptive cruise control, lane keeping assist, lane departure warning, traffic sign recognition, blind-spot monitoring with rear cross-traffic alert, and automatic high beams). The Integra, though, gets a superior collision mitigation braking system with pedestrian detection, as well as an adaptive cruise control system with low-speed follow and traffic jam assist. Not only that, but it’s eligible for parking sensors and rain-sensing windshield wipers, neither of which can be ordered on the Civic Si.
