Acura Integra vs. Honda Civic Si: Sibling Rivalry Comparison

Cross-shopping a sport compact often means comparing an Acura against a Honda built from the exact same engineering playbook. This guide breaks down where the Acura Integra and Honda Civic Si actually differ, from the engine bay to the cabin, so you can pick the sibling that fits how you drive.

The Acura Integra vs Honda Civic Si debate comes down to shared 200-horsepower turbocharged engines with very different execution. The Integra adds luxury cabin materials and available ELS Studio premium audio, while the Civic Si keeps things simpler with a manual-only lineup starting near $32,690.

Our product specialists at Ron Tonkin Acura spend every day walking Portland area drivers through the Integra lineup, including the manual-equipped A-Spec with Technology Package that true enthusiasts ask for by name. Below, we compare performance, transmission choices, interior tech, and starting pricing so you know exactly what separates these two sport compacts before you visit our showroom.

Key Points: Acura Integra vs Honda Civic Si

• Shared engine, different mission. Both the base Acura Integra and the Honda Civic Si use a 1.5L turbocharged 4-cylinder producing an identical 200 horsepower and 192 lb-ft of torque, a real reflection of their sibling relationship under Honda Motor Co.
• Only one sibling guarantees a manual on every build. The Civic Si ships exclusively with a 6-speed manual transmission, while the Integra pairs a CVT with most trims and reserves the 6-speed manual for the A-Spec with Technology Package and the Type S.
• Luxury cabin comfort comes standard on the Integra. Acura’s Precision Cockpit layout, available ELS Studio 3D audio, and more sound-deadening material separate the daily-drive experience even when the horsepower numbers match.

2026 Acura Integra vs. Honda Civic Si: Specs at a Glance

Shoppers cross-referencing these two sport compacts usually want the numbers side by side before anything else. Here’s how the lineups stack up.

*Starting MSRP figures include the manufacturer’s destination charge and exclude tax, title, license, and dealer-installed options. Fuel economy figures are EPA estimates and actual mileage varies by driving conditions. Pricing is set by Acura and Honda and is subject to change. Contact Ron Tonkin Acura to confirm current Integra pricing and availability.

A few things stand out once the numbers sit next to each other. The base Acura Integra makes the exact same horsepower as the Honda Civic Si, which surprises a lot of first-time cross-shoppers who assume the luxury badge buys more power. Step up to the Integra Type S and output jumps to an estimated 320 horsepower, a tier the Civic Si lineup doesn’t reach at any price. The Integra’s warranty runs a full year longer than the Civic Si’s on both bumper-to-bumper and powertrain coverage, with more mileage allowance on each. Fuel economy tells a similar story: the CVT-equipped Integra returns an EPA-estimated 32 mpg combined, noticeably better than the manual-only Civic Si’s estimated 31 mpg combined.

How the Acura Integra and Honda Civic Si Compare on Performance

The Acura Integra and Honda Civic Si share a corporate engine family, and it shows in the numbers. Both the base Integra and the Civic Si post an estimated 0-60 mph time of under 7 seconds, backed by that identical 1.5L turbocharged engine and torque band that peaks between 1,800 and 5,000 rpm. The Civic Si tunes that shared architecture through Honda’s VTEC valve system for a sharper throttle response at the top end.

The Integra Type S changes the conversation entirely. Its 2.0L turbocharged engine makes an estimated 320 horsepower and 310 lb-ft of torque, reaching 60 mph in an estimated 5.1 to 5.2 seconds. The Type S is the sibling built for drivers who want more than the Civic Si offers at any trim level, backed by Brembo brakes and a helical limited-slip differential the Civic Si doesn’t offer.

Manual Transmission and Handling: Which Sibling Drives Sharper?

Transmission choice is where these two vehicles split hardest. The Honda Civic Si comes exclusively with a 6-speed manual transmission featuring rev-match control and a lightweight single-mass flywheel, so every Civic Si buyer gets the same driver-focused setup.

The Acura Integra takes a different approach. A CVT with paddle shifters is standard on the base, A-Spec, and A-Spec with Technology Package trims, and the 6-speed manual with rev-match control is available only on the A-Spec with Technology Package, plus standard on the Type S. Shoppers who want three pedals need to specify the right Integra trim. The Type S adds a Dual Axis Strut front suspension and adaptive dampers most Civic Si buyers won’t find on their side of the family tree.

Inside the Cabin: Acura Integra Interior vs. Honda Civic Si Features

Step inside either car and the sibling relationship gives way to two different missions. The Acura Integra interior centers on the Precision Cockpit layout, with available ELS Studio 3D premium audio and additional sound insulation that keeps road and engine noise out of the cabin at highway speed.

The 2026 Honda Civic Si counters with genuine tech upgrades of its own, including Google built-in infotainment with a 3-year data plan, a 10.2-inch digital instrument cluster, and a Bose premium audio system. Cargo space favors the Integra by a wide margin at 24.3 cubic feet against the Civic Si’s 14.1 cubic feet, a real difference for drivers who haul gear as often as they drive for fun.

Value and Ownership: Acura Integra vs. Honda Civic Si Pricing

The Honda Civic Si undercuts the base Acura Integra by roughly $2,000 at MSRP, a gap that narrows once buyers start comparing similarly equipped trims. The Integra A-Spec with Technology Package, the trim most cross-shoppers actually compare against the Civic Si, starts at an estimated $40,495 including destination, reflecting its added luxury features and standard manual availability.

AcuraWatch, Acura’s suite of standard driver-assistive safety technology, comes on every Integra trim, including collision mitigation braking, adaptive cruise control, and lane keeping assist. Ownership costs beyond the sticker price, including insurance and long-term resale value, vary by trim and driving history, so we always recommend a direct comparison with your Ron Tonkin Acura product specialist before deciding.

Which Is Right for You: Acura Integra or Honda Civic Si?

Both vehicles come from the same corporate family, and both are genuinely well-built sport compacts. The right choice depends on what you’re actually optimizing for.

• Want a guaranteed manual transmission at the lowest price: The Honda Civic Si delivers that every time, no trim-picking required.
• Want a manual with a more upscale cabin and better fuel economy: The Acura Integra A-Spec with Technology Package pairs the 6-speed manual with Precision Cockpit design and available ELS Studio audio.
• Want more performance than either base engine offers: The Acura Integra Type S is the only sibling with the 2.0L turbocharged engine and 320 horsepower.
• Want maximum cargo room for daily use: The Integra’s 24.3 cubic feet of cargo space outclasses the Civic Si’s 14.1 cubic feet.
