Courtesy of a complete road-to-roof redesign in 2014, the stylish and luxurious 2015 Chevrolet Impala sedan aims to erase memories of the model's recent rental-car past. Channeling some of the sleek design that characterized the beloved Impalas of the 1960s and '70s, the new Impala shares underpinnings with the Buick LaCrosse and the Cadillac XTS, offering a lively 305-horsepower 3.6-liter V6, decent chassis dynamics, a stretch-out back seat, a quiet cabin, a huge trunk with 18.8 cu ft. of space and the latest version of the Chevrolet MyLink infotainment system. Fitted with a standard 10 airbags, the 2015 Impala is also available with forward collision alert, lane-departure warning, rear cross-traffic alert, crash-imminent automatic braking and full-speed adaptive cruise control.

New for 2015 is standard OnStar with 4G LTE connectivity and a mobile Wi-Fi hot spot for up to 10 devices. A new fuel-saving start/stop system that shuts off the engine at stoplights and automatically restarts it when the driver releases the brake is now standard on Impalas with the base 2.5-liter 4-cylinder engine. The 3.6-liter V6 is also available in a flex-fuel version that can run on unleaded regular fuel, E85 or any combination of the two. Additionally, Chevrolet built a small number of 3.6-liter V6 2015 Impalas fitted to run on compressed natural gas (CNG) or unleaded regular fuel with an estimated combined driving range of 500 miles. The previously available Impala Eco gas-electric hybrid is dropped for 2015.

What We Like

4G LTE Wi-Fi hot spot; V6 performance; roomy back seat and trunk; interior quiet; capable handling; MyLink infotainment; seamless restart of stop/start system

What We Don't

Poor rearward visibility; no all-wheel drive; tiny trunk space of CNG V6-equipped cars

Fuel Economy & Engine Specs

Chevrolet outfits the Impala LS, LT and LTZ with a standard 2.5-liter dual-overhead-camshaft (DOHC) 4-cylinder featuring four valves per cylinder and direct injection. It produces 196 hp and 186 lb-ft of torque on regular unleaded gas and returns 22 miles per gallon in the city and 31 mpg on the highway with the standard 6-speed automatic transmission. For 2015, a fuel-saving stop/start system adopted from the now-discontinued Eco hybrid model that automatically shuts off the engine at stoplights is added to Impalas with the base 2.5-liter 4-cylinder.

Available on LT and LTZ models is a peppy 3.6-liter DOHC V6 that produces 305 hp and 264 lb-ft of torque, mated to a 6-speed automatic. It also runs on regular unleaded fuel, and a flex-fuel version is available that can use clean-burning E85 or gasoline. Flex-fuel models have a yellow gas cap. Fuel-economy ratings are 18 mpg city/29 mpg hwy on gasoline and 14 mpg city/22 mpg hwy with the less energy-dense E85.

Chevrolet also made a small number of 2015 Impalas with a bi-fuel 3.6-liter V6 that can run on CNG or gasoline, mostly for fleet or corporate customers. The CNG system and dual fuel tanks add nearly 400 pounds, and the CNG tank reduces trunk space by almost half to just 10 cu ft. But by using the fuel in both tanks (the driver can switch fuel sources on the fly), cruising range is estimated at 500 miles. On CNG, output of the V6 drops to 230 hp and 218 lb-ft of torque, and fuel-economy estimates sink to 16 mpg city/24 mpg hwy.

Standard Features & Options

The 2015 Chevrolet Impala is available in LS, LT and LTZ trims.

Typical LS equipment includes air conditioning, a power driver's seat with adjustable lumbar, cruise control, cloth seat trim, a tilt-telescopic steering wheel, remote keyless entry, a trip computer, Bluetooth, the OnStar communication system with 4G LTE, a 6-speaker AM/FM/CD stereo with an MP3 decoder and steering-wheel audio controls, SiriusXM satellite radio, HD Radio, a 60/40 fold-down rear seat, automatic headlamps, 18-inch steel wheels, stability and traction control, anti-lock brakes, a 2.5-liter 4-cylinder engine with a 6-speed automatic transmission and power door locks, windows and mirrors.

Moving up to the 1LT adds dual-zone automatic climate control, an 8-in touchscreen audio system with MyLink and voice recognition, hidden in-dash storage, premium cloth and faux-leather seats and a leather-trimmed steering wheel, dash and shifter. Upgrading to the 2LT adds 18-in alloy wheels and the 3.6-liter V6 engine.

The top-of-the-line LTZ brings standard leather seating, remote engine start, a proximity key, a power passenger seat, a chrome-tipped exhaust, an auto-dimming rearview mirror, a blind spot monitoring system, lane-departure warning, rear park assist and a backup camera. The 2LZ version of the LTZ comes with the 3.6-liter V6. It's also available with adaptive cruise control, forward collision alert, rear cross-traffic alert, a power moonroof, a navigation system and 19- or 20-in alloy wheels.


Well-equipped V6 models will cost more than 4-cylinder versions, but they're worth the extra money. The Impala is a top-selling full-size sedan and with lease returns coming back into the used-car market, so there should be a good supply of pre-owned examples to choose from.

The National Highway Traffic Safety Administration (NHTSA) has announced the following recalls for the 2015 Impala:

On models with heated and ventilated front seats, the front passenger airbag may deploy in a crash with a child seat in the front passenger seat, increasing the risk of injury to the child.

The electric parking brake may not release fully, dragging the rear brakes and increasing the risk of a fire.

The center-console storage compartment door may unlatch in a crash, increasing injury risk.

Recall repairs are required by law, even if the vehicle is out of warranty. Your dealer can check to see if the repairs were performed, and if not, they'll fix the car at no charge to you.

Safety Ratings & Warranties

The NHTSA initially gave the 2015 Impala a 5-star overall rating, with five stars for frontal and side impacts and four for rollover performance. Subsequently, under newer safety evaluation guidelines, the NHTSA revised the 2015 Impala to four stars overall, with four for frontal and side impacts and rollover performance.

The independent Insurance Institute for Highway Safety gave the 2015 Impala a Good rating for moderate-overlap front and side impacts. It did not test for small-overlap frontal impacts, roof strength or seat and head-restraint performance.

General Motors covered the 2015 Impala with a 3-year/36,000-mile bumper-to-bumper warranty, a 5-year/100,000-mile powertrain warranty with roadside assistance and a 6-year/100,000-mile corrosion-perforation warranty.

Chevrolet certified pre-owned (CPO) cars cannot have more than 75,000 miles on the odometer and must be 5 years old or less. Every CPO Impala undergoes a 172-point inspection. Those that pass receive a 12-month/12,000-mile bumper-to-bumper warranty, plus whatever remains on the original transferable 5-year/100,000-mile powertrain coverage.

Other Cars to Consider

2015 Ford Taurus -- Ford's biggest car is available with a 240-hp 2.0-liter turbo 4-cylinder that achieves 22 mpg city/32 mpg hwy, plus a standard 288-hp 3.5-liter V6 and the 365-hp 3.5-liter twin-turbo SHO V6. The Taurus boasts the biggest trunk in the segment at 20.1 cu ft., but the interior is not overly spacious. The 2015 model adds a standard backup camera and SYNC infotainment. Taurus is available with front- or all-wheel drive.

2015 Volkswagen Passat -- The interior of the U.S.-built Passat is plain-looking but offers a roomy cabin and a large trunk. Engine choices include a 140-hp 2.0-liter 4-cylinder turbodiesel, a 170-hp 1.8-liter turbo 4-cylinder gas engine and a 280-hp 3.6-liter premium-fuel V6.

Autotrader's Advice

After several decades of being the default choice for corporate and rental-car fleets, the 2015 Impala is finally the flagship its position as the largest regular-production Chevrolet sedan would suggest. The roomy, stylish Impala is best experienced in the well-equipped LT or range-topping LTZ trim with the brisk-performing 305-hp 3.6-liter V6. Look for a CPO example, if available, and check with the dealer to make sure that the 2015 Impala you're considering has had all safety-recall items resolved.
