The 2025 Acura Integra Type S arrives as a turbocharged, four‑door hatchback that eclipses the early‑2000s Honda RSX Type S in both performance and everyday usability. While the RSX was a lightweight, naturally aspirated two‑door coupe, the Integra packs 320 hp, a broader cabin and a modern design, marking a generational shift for Acura’s sport‑compact line.

Turbocharged 320 hp K20C8 engine triples RSX’s output

The Integra Type S replaces the RSX’s high‑revving K20Z1 with a forced‑induction K20C8 shared with the Civic Type R, delivering 320 hp and 310 lb‑ft of torque, according to the source. By contrast, the RSX’s naturally aspirated unit produced roughly 201 hp and 140 lb‑ft, with a redline of 8,100 rpm versus the Integra’s 7,000 rpm. This power surge translates to a 0‑60 mph time of 5.5 seconds, shaving a full second off the RSX’s 6.7‑second run.

Four‑door hatchback adds 13.6 inches of length and 6.9 inches of width

Dimensions reveal a dramatic size increase: the Integra measures 186.0 inches long, 74.8 inches wide and 55.4 inches tall, compared with the RSX’s 172.4‑inch length and 67.9‑inch width.. the wheelbase stretches to 107.7 inches, 6.5 inches longer than the RSX’s 101.2 inches, allowing rear legroom to jump from 29.2 inches to 37.4 inches. Front headroom improves modestly, while curb weight climbs to 3,199 lb from the RSX’s 2,840 lb, yet front‑bias weight distribution stays near 62‑63 percent.

Styling cues signal performance without sacrificing maturity

Visually,the Integra Type S adopts a wider body, larger wheels, functional cooling vents, a rear diffuser and a three‑tip exhaust, creating a more aggressive silhouette than the RSX’s subtle coupe lines.. Despite the sportier intent, the design retains a refined aesthetic that aligns with Acura’s premium positioning, rather than the overt hot‑hatch look of many rivals.

Fuel economy stays competitive despite added power

Fuel‑efficiency ratings show only a marginal gain: the Integra posts 21 mpg city, 28 mpg highway and 24 mpg combined, versus the RSX’s 20/28/23 mpg. Estimated driving range remains near 300 miles for both models, indicating that the turbocharged engine’s efficiency offsets its larger displacement and weight.

Who will benefit from the Integra’s blend of speed and space?

The source notes that the Integra’s rear seat can comfortably accommodate adults, a stark contrast to the RSX’s rear seats, which were best suited for children or short trips. This shift suggests Acura is targeting buyers who want a daily driver that can also serve as a practical family vehicle, without compromising on performance.

What remains unverified about the Integra’s real‑world durability?

While long‑term testing recorded impressive acceleration figures, the source does not address long‑term reliability of the turbocharged K20C8 under daily stress, nor does it provide comparative warranty or maintenance cost data versus the naturally aspirated RSX.
