Except for in Britain, Honda did not offer the more powerful 1.6 DOHC fuel injection engine (in the UK known as the Integra EX16) in Europe.

Vehicles installed with a carburetor earned 15.4 km/L (44 mpg‑imp; 36 mpg‑US) in Japanese Government emissions tests and 115 PS (84.6 kW; 113.4 bhp), and 26 km/L (73 mpg‑imp; 61 mpg‑US) at consistent speeds above 60 km/h (37.3 mph).

Vehicles with PGM-FI earned 14.4 km/L (41 mpg‑imp; 34 mpg‑US) in Japanese Government emissions tests with 135 PS (99.3 kW; 133.2 bhp), and 24.5 km/L (69 mpg‑imp; 58 mpg‑US) above 60 km/h (37.3 mph).

[15] In Japan, the Integra took the entry level marketing position at Honda Verno, below the sporty Prelude and larger, luxury focused Vigor.

Compared to the US, the European Integra was aimed downmarket and generally lacked equipment, with neither trim level (LX or EX) offering painted bumpers, central locking, power windows, nor air conditioning, even though a small number of fully equipped, left-hand drive fuel-injected Integras were sold in the Netherlands.

The Integra EX16 did offer a sunroof, painted bumpers, a rear spoiler and Hi-Fi stereo equipment, but neither electric windows, central locking nor air conditioning were available.

[16] Being designed as the successor of the Honda Quint, the Integra is closely related to the Civic, although it featured a small list of key upgrades over its smaller stablemate to help merit a price increase over the CRX Si, which was otherwise the sportiest subcompact vehicle being offered by Honda Verno; enlarged 4-wheel disc brakes replaced the small front-disc/rear-drum setup used by the Civic and CRX, suspension calibration was re-worked, better tires were used and a 113-hp DOHC fuel-injected 16-valve engine was used in place of the SOHC unit from the CRX Si.

The Integra received a minor facelift in 1987 for the 1988 model year which featured slightly reshaped indicator lights, an improved climate control system and an update of the instrument clocks.

The Integra coupe has a wheelbase that is 3.9 in (99 mm) longer than the previous generation and weights approximately 190-235 lbs more depending on the model.

Called the ESi, it offered 140 PS (103 kW; 138 hp) at 6,300 rpm and was only available in conjunction with a 4-speed automatic transmission.

The then-Emperor of Japan, Akihito, until he discontinued driving shortly after his 85th birthday, maintained a gray 1991 Integra sedan with the 1.6 L engine, and regularly drove within the boundaries of the Imperial Palace.

Less than 5,000 of the 1992–1993 model years Acura Integra GS-R were produced for North America; this is confirmed by the vehicle identification number sequence of these cars.

[21] From 1998 onward, non-JDM Integras (including Type R models) received a facelift to the front bumper which moved the embossed "INTEGRA" label to below the left headlights, eliminated the horizontal strut across the radiator grille and reshaped the headlight housing, turn signal housing and lower bumper.

Dealer-installed options for the third-generation Integra included: security system, 15-inch alloy wheels, trunk mat, splash guards, fog lights, rear-wing spoiler, moonroof (liftback only), CD changer, leather seats, leather-wrapped shift knob and steering wheel.

[citation needed] In 1995, power ratings dropped to 148 hp (110 kW; 150 PS) and 124 lb⋅ft (168 N⋅m) of torque due to U.S. emissions regulations.

LS: Luxury Sport, was available in both liftback and sedan a leather-wrapped steering wheel and shift knob.

Equipped with the 1.8-liter DOHC VTEC (B18C5) 4-cylinder engine producing 195 hp (145 kW; 198 PS) limited-slip differential, unique interior trim, front spoiler, high rear wing, Type R badging, lowered sport suspension, and unique 7-spoke 5-lug 15-inch alloy wheels.

Deletes air conditioning, leather upholstery, tilt/height adjustable driver seat, visor mirrors, power moonroof, and cruise control.

These were the result of extensive changes, including a strengthened chassis with extra spot welds and thicker metal around the rear shock towers and lower subframe, weight reduction (reduced sound insulation, 10 percent thinner windscreen, lighter wheels), more power, rev limiter set at 8,600 rpm JDM (8,500 rpm USDM, 8,700 rpm UKDM), hand-built engine featuring hand-polished and ported intake ports, high-compression pistons, undercut valves and revised intake and exhaust systems, and suspension upgrades.

The JDM version was significantly lighter than the SiR Integra (The 96–97 spec model could delete the air bags, air conditioning, rear wiper, radio, center console, clock, power steering and anti-lock brakes), However, there is only a 33 lb[citation needed] (15 kg) net weight difference between the USDM Integra Type R and the Integra GS-R because the extra metal and cross bracing in the Type R negate much of the 98 lb of weight reductions.

For the European, Australian and New Zealand market, the Integra was sold as a Honda with the four headlight front-end design.

A final trim version offered in mid-2000 onwards for the JDM market (known as the "Type Rx") came factory fitted with motorized folding mirrors, dashboard clock, blue-hue carbon trim interiors, and an audio system as part of the standard package.

Available only in the four-door sedan, the ZXi4WD[28] (93–95) and Xi4WD[29] (95-00) had 1.6L SOHC ZC engines coupled to a version of Honda's Real Time 4WD.

The Integra SJ (standing for "Sedan Joyful") was a rebadged Civic Ferio (a Honda Primo product) with modified headlamps and grille similar to the Orthia's and slightly larger rear lights that were also utilized on the Japanese market Civic LEV sedan.

Honda's press material of the time indicated that the SJ was intended to provide a "formal sedan" for the Integra range; another reason may have been to sell Ferios using a more sporting model name at Honda Verno dealerships in Japan, as was the case with the Nissan Laurel Spirit.

In June 2006, Honda discontinued the Integra after its final 300 cars were sold, due to the shrinkage of the coupe market.

Also, the introduction of the similarly powerful and less expensive 2006 model-year Honda Civic Si was there to fill in the gap left by the RSX.

The Integra Type R came equipped with Recaro seats, four-piston Brembo front brakes, a close-ratio 6-speed manual transmission, a limited-slip differential, variable back-pressure exhaust system, and a stiffer suspension.

The Acura Integra was reintroduced in North America on June 2, 2022 for the 2023 model year as a 5-door liftback that replaced the ILX sedan.

The BTC-T version of the Integra was very successful in the British Touring Car Championship, winning 27 races and becoming the champion in 2005 and 2006, despite being only entered by privateer teams.
