The GTI's 2.0-liter turbo makes 241 horsepower and 273 lb-ft of torque, sent through a 7-speed DSG dual-clutch automatic to the front wheels; VW dropped the manual after 2024. The VAQ electronically controlled limited-slip differential is standard, and the Autobahn trim adds DCC adaptive dampers. EPA estimates come in at 24 city/32 highway mpg.

The Civic Si answers with 200 horsepower and 192 lb-ft from its 1.5-liter turbo, and it only comes one way: a 6-speed manual with rev-matching, a helical limited-slip differential, and a fixed sport suspension. It is EPA-estimated at 27/37 mpg, so the Honda wins the fuel-economy column while giving up 41 horsepower. If you insist on three pedals, the Si is the pick; if you want the faster car with two, the GTI is.

Every GTI trim, S through Autobahn, centers on a 12.9-inch touchscreen with wireless App-Connect for Apple CarPlay and Android Auto, backed by the Volkswagen Digital Cockpit Pro instrument display and available wireless charging.

The Si runs a 9-inch touchscreen with Apple CarPlay and Android Auto, a 10.2-inch digital instrument cluster, and a standard 12-speaker Bose system, which is the strongest single tech item on either car. The GTI counters with the larger center screen and an available harman/kardon audio upgrade.

VW's IQ.DRIVE suite is standard on the GTI: Front Assist forward collision warning and autonomous emergency braking, Active Blind Spot Monitor, Rear Traffic Alert, Lane Assist, Adaptive Cruise Control, and Travel Assist for semi-automated highway support.

Honda Sensing is standard on the Si with Collision Mitigation Braking, Road Departure Mitigation, Adaptive Cruise Control, and Lane Keeping Assist, plus blind spot information. Both cars treat driver assistance as standard equipment rather than an option package, so this category is closer to a tie than a tiebreaker.

The GTI's cabin is the more configurable one: plaid cloth sport seats on the S keep the tradition alive, the SE moves upmarket, and the Autobahn brings leather and three-zone climate control. Heated front seats are standard, and the full interior rundown covers each trim.

The Si's cabin is set at one specification: aggressively bolstered sport seats with red stitching and a leather-wrapped steering wheel. Both seat five, but the body styles split the practicality question, a 14.1-cubic-foot sedan trunk in the Honda versus 19.9 cubic feet under the GTI's hatch with the seats up.

The GTI is the compact one: 168.8 inches long on a 103.6-inch wheelbase, 70.4 inches wide and 57.6 tall. That short footprint is why it feels wieldy on a tight on-ramp and parks easily downtown, while the long roof keeps the cargo area usable.

The Si stretches 184.0 inches on a 107.7-inch wheelbase, more than 15 inches longer than the GTI, which buys it a roomier rear seat and a longer highway stance. Choose by shape: the GTI packs its space into a hatch, the Si spreads it across a sedan.
