A six-way power seat was a new option, as was "Speedminder," which allowed the driver to set a needle at a specific speed, which triggered a buzzer when exceeded.

Right-hand drive cars were made in Oshawa, Ontario, Canada, for New Zealand, Australia, and South Africa and assembled locally from CKD or SKD kits.

The 1963 Impala featured rectilinear styling with an engine-turned aluminum rear taillight panel surrounded by a chrome border on SS models.

A high-rise, two-piece aluminum intake manifold and dual Carter AFB carburetors fed a 13.5:1 compression ratio to produce 430 horsepower (320 kW) and 575 lb⋅ft (780 N⋅m) of torque.

[26] Right-hand drive cars were made at GM's Oshawa plant in Canada and often shipped overseas in kit form for assembly in South Africa, New Zealand and Australia.

The package also included upgraded tires on station wagon wheels, springs, shocks and special sintered metallic brake linings.

This package was available on any 1967–69 2-door Impala and it included Chevrolet's 427 cubic inch V8, F41 Sport Suspension, redline tires, and unique SS 427 badges on the body.

The Super Sport's blackout rear trim strip below the triple taillights was also used, with the "Impala SS" emblem replaced by a large "Caprice by Chevrolet" badge.

Like all GM "B" bodied cars, Impala got a new power ventilation system that remained on while the ignition was on, and included both large vents in the instrument panel and louvers in the trunk.

One ACRS-equipped Impala was preserved and remains a witness to the ability of an American automaker to design life saving safety systems into cars without a government mandate.

The front end was also freshened as in previous years, with a new grille and headlight bezels, a new header panel, and a bumper with a drop down center section.

The Caprice model was revised with a new front end with a swept back style header panel with recessed headlight buckets, a new hood, and new fenders.

Four-door models got new rooflines; the hardtop Sport Sedan got a small triangular "opera window" carved out of the wide roof panel.

For the 1980 model year, a mid-cycle refresh replaced this complex backlight in the coupe with a more upright nearer flat glass, although the overall design remained similar.

Inside, the car came with a central console with cup holders (1994 and 1995 models) and a storage compartment, leather seats embroidered with the Impala SS logo, and a standard leather-wrapped steering wheel.

Marblehead Gray Metallic had been planned for that final year; however, the option was cancelled at the last minute even though many trim part numbers for the color had already been designated.

[42] The LS came factory-equipped with cloth bucket seats upgradeable to leather with center console and floor shift, color-keyed "Impala" door scripts and trunk badge, anti-lock brakes, traction control system, keyless remote entry, integrated foglamps, aluminum wheels upgradeable to alloy wheels, rear spoiler (optional on the base models), 4-gauge instrument cluster (with tachometer), and the larger 200 horsepower (149 kW) 3.8 liter (231 cu in) L36 V6.

[48] To commemorate Chevrolet's long relationship with the Indianapolis Motor Speedway and the Indianapolis 500 race, a limited edition (4,088 produced) Impala Indy SS was offered in 2004, notably featuring a black grille with gold Chevrolet bowtie emblem that would be carried over to all Impala models in 2005, various Indy logos on the exterior and interior, 17-inch chrome wheels, and gauge cluster package.

However, the Ford Crown Victoria P71 still held the sales lead and was preferred by most agencies due to its larger size, much more durable V8 engine, rear-wheel drive layout, and body-on-frame platform.

A mechanical refresh for 2012 brought the revised 3.6-liter V6 (with variable valve timing) to all trims as the single engine offering, paired with an updated 6-speed automatic transmission.

A tire pressure monitoring system, cruise control, and a CD player were standard on all models, and a factory spoiler was an available option.

Based on the LT, it added a FE3 Sport Suspension (replacing the FE1 Touring Suspension), four-wheel ABS, eighteen-inch SS-style alloy wheels (replacing the 16-inch wheels), rear SS style spoiler, "50th Anniversary" Impala badges on the C-pillars, two-tone, leather-trimmed seats with "50th" logos embroidered on the front headrests, eight-way power-adjustable driver seat, leather-wrapped steering wheel with accent-color threading including audio controls, ebony carpet, ebony floor mats with accent threading, "50th" Anniversary emblems on the sill plates, and a choice of two premium exterior colors: Black Granite Metallic and Red Jewel Tintcoat.

A Luxury Edition package, last seen on the 2011 model, returned as an option on the LT and featured perforated leather seating surfaces, dual front heated bucket seats with driver's side 8-way and passenger's side 6-way power adjusters, inside rearview auto-dimming mirror, Universal Home Remote, outside heated power adjustable mirrors, Bose 8-speaker premium sound system, six-disc in-dash CD changer that played MP3 and WMA files, with Radio Data System, Sirius-XM satellite radio, as well as an auxiliary input.

The new Impala joined the Honda Civic as a rare factory-made CNG car to come straight from a major automaker and available for retail sales.

[93] The Impala went on sale in South Korea as an export vehicle for the 2016 model year, marking the first time that Chevrolet had offered an American-built full-size sedan in the Korean market.

LTZ (Premier) – Adds to LT: 3.6L VVT V6 gasoline engine with flex-fuel capability, 19-inch aluminum-alloy wheels, keyless access with push-button start, luxury leather-trimmed seating surfaces, dual heated front and rear seats, heated leather-wrapped steering wheel, exterior LED daytime running lamps (DRLs), rearview backup camera system, chrome-accented color-keyed exterior door handles with touch sensors, and chrome side mirrors.

There was speculation that GM would discontinue the Impala in 2018 because of declining sales of American full-size sedans, in order to make room for more production of crossover SUVs.

[citation needed] GM made some minor structural enhancements to the Impala, beginning in December 2009; models produced after that received a "Good" in the IIHS frontal offset crash test.

[108] In September 2009, a local news station's investigative team in Rhode Island discovered that GM's fleet customers who purchased the 2006–2009 Impala were able to order them with the side-curtain airbags deleted for a savings of $175 per vehicle.

[111] (GM was also facing a similar legal dispute regarding a pre-bankruptcy upgrade to its OnStar system which left thousands of users without service in violation of their paid-up contracts.)
