2015 Buick Regal Overview

Is the 2015 Buick Regal a Good Used Car?

Yes, the 2015 Regal is a good used car. Though its powertrains aren't overly energetic, it handles well and rides smoothly, and the eAssist mild-hybrid model gets decent gas mileage (though the base engine's fuel economy is subpar). Inside, the Regal looks and feels more elegant than many rivals, and it has a decent number of features. Passenger space is good upfront, but rear headroom and trunk space are a disappointment.

How Much Does the 2015 Buick Regal Cost to Own?

Expenses for fuel, insurance, maintenance, and repairs for the 2015 Buick Regal are estimated to be around $26,500 over five years, or $5,300 per year. That’s one of the highest estimates in the midsize car class.

Is It Better to Buy a Used or New Buick Regal?

The 2015 Regal's average list price of $17,600 is about $7,500 lower than the starting price for a 2019 Buick Regal. Aside from price, the two models have plenty of differences, as Buick redesigned the Regal for the 2018 model year. The 2019 Regal comes in liftback and wagon body styles, and it has much more room for passengers and cargo than the 2015. The 2019 model is no longer available with the eAssist powertrain, but it does offer a V6 that's stronger than any 2015 Regal offering.

When it comes to features, the 2019 is well ahead of the previous generation. It comes standard with Android Auto, Apple CarPlay, and Teen Driver, which lets you do things like set audio and speed limits for secondary drivers. It also offers amenities like wireless device charging, lane keep assist, automatic emergency braking, and rear parking sensors.

If those updates aren’t important to you, consider shopping for an older vehicle. Doing so could save you thousands of dollars.

Read about the new Regal »

The price of a used 2015 Buick Regal ranges from $14,500 to $22,000. There are a few new midsize cars that start around the high end of that price range, including the 2019 Mazda6, Chevrolet Malibu, and Hyundai Sonata. These cars have larger trunks and offer features you can't get in the 2015 Regal.

There are also many new small cars with comparable price tags. Small cars may not have quite as much passenger space, but they get good fuel economy, and many come with more active safety features than the 2015 Buick Regal. Several models are also available as hatchbacks, so they have much more cargo space than a used 2015 Regal. Be sure to check out alternatives like the 2019 Honda Civic and 2019 Kia Forte before you make your decision.

Which Model Year of the Buick Regal Is Best?

Buick reintroduced the Regal for the 2011 model year after a short hiatus. It received a significant refresh for the 2014 model year, giving it updated interior and exterior styling, a revised powertrain lineup, and available all-wheel drive. The 2015 model gained a standard Wi-Fi hot spot, while the 2016 model received Apple CarPlay but lost the available eAssist powertrain. If the infotainment upgrades aren't important to you, opt for a 2014 model to save some cash.

Which Used Buick Regal Model Is Right for Me?

The Buick Regal comes in four trims: base, Premium I, Premium II, and GS. The base trim has enough features to satisfy most shoppers. If you want more driver assistant features than the standard rearview camera, you’ll have to step up to a Premium II trim, which includes the Driver Confidence Package I. This package comes with safety technologies such as blind spot monitoring, lane departure warning, and forward collision warning with automatic braking.

What Does Buick's Certified Pre-Owned Warranty Cover?

Buick offers a certified pre-owned program for vehicles six years old or less and with fewer than 75,000 miles. Eligibility is determined by the vehicle’s initial sale date. Qualifying vehicles receive a one-year/12,000-mile bumper-to-bumper limited warranty after the four-year/50,000-mile new-car warranty expires. This warranty includes free maintenance for two years or 24,000 miles, and the original new-car powertrain warranty is extended to six years or 100,000 miles. Buick CPO models must pass a 172-point inspection. Additional benefits like towing and roadside assistance may be available, so read Buick’s warranty page carefully.

Buick has one of the better CPO programs among affordable carmakers. According to our analysis, only Kia and Mini have better programs.

2015 Buick Regal Versus the Competition

Which Is Better: 2015 Buick Regal or 2015 Chevrolet Malibu?

The 2015 Chevrolet Malibu has a high safety score and earns a perfect reliability rating. The Malibu and Regal both have elegant cabins and similar features lists. The Malibu has a larger trunk, however. It also feels a bit more energetic from behind the wheel, and it's more fuel-efficient.

Which Is Better: 2015 Buick Regal or 2015 Toyota Camry?

The 2015 Toyota Camry is one of our highest-rated midsize cars. It has a quiet cabin with plenty of room, and it gets great gas mileage – on par with the mild-hybrid Regal. The Camry also has more trunk space and an easier-to-use infotainment system than the Regal. Finally, the Camry is one of the few midsize cars to earn a higher reliability rating than the Regal.

2015 Regal Performance

How Does the 2015 Buick Regal Drive?

The 2015 Buick Regal comes with a 259-horsepower turbocharged four-cylinder engine. A mild-hybrid eAssist powertrain is available, which includes a four-cylinder engine and a small electric motor that make a combined 182 horsepower. All Regal models come standard with a six-speed automatic transmission. A six-speed manual is available in front-wheel-drive GS models.

Neither powertrain feels overly impressive, but the turbo-four engine delivers better acceleration than the more sluggish mild hybrid eAssist. The Regal rides smoothly over most road surfaces and handles well, especially in the GS trim. All-wheel drive is available for added road grip.

Does the 2015 Buick Regal Get Good Gas Mileage?

With FWD and the base engine, the Regal gets an EPA-estimated 21 mpg in the city and 29 mpg on the highway. With a manual transmission, those numbers drop to 20/31 mpg city/highway, and they dip to 19/27 mpg with AWD. These ratings are lower than you'll get from several class rivals.

Expect better fuel economy from eAssist models: 24/35 mpg city/highway. Those ratings are more in line with competitors.

How Many People Does the 2015 Regal Seat?

The Regal seats five and comes standard with leather upholstery, heated front seats, and a power-adjustable driver seat. Available features include a power-adjustable passenger seat and a heated steering wheel. GS models come with front sport seats with added side support.

The Regal has a first-rate interior. It's stylish and built with premium materials. Front-seat occupants enjoy comfortable seating and plenty of support, even on long drives.

How Many Car Seats Fit in the 2015 Buick Regal?

Buick Regal Cargo Space

The Regal eAssist’s battery takes up some trunk space, reducing cargo capacity to 11.1 cubic feet in those models.

2015 Regal Length and Weight

The 2015 Regal is a little under 16 feet long. Its curb weight ranges from 3,600 to 3,981 pounds.
