Regardless of its engine, the Regal Sportback’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Genesis only offers an automatic engine start/stop system on the G70 2.0T Automatic.

The Regal Sportback has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The G70 doesn’t offer a cap-less fueling system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Buick Regal Sportback higher (5 to 6 out of 10) than the Genesis G70 (3). This means the Regal Sportback produces up to 23.4 pounds less smog-producing pollutants than the G70 every 15,000 miles.

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The Regal Sportback has a standard brake assist system to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The G70 doesn’t offer a brake assist feature.

The Regal Sportback stops much shorter than the G70:

The Regal Sportback has 4.2 cubic feet more passenger volume than the G70 (98 vs. 93.8).

The Regal Sportback has .6 inches more front shoulder room, .5 inches more rear headroom, 2.1 inches more rear legroom and .8 inches more rear shoulder room than the G70.

Unlike the driver-only memory system in the G70 3.3T/Elite/2.0T Manual/Prestige/Sport, the Regal Sportback offers an optional driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Regal Sportback’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The G70 does not have an oil pressure gauge.

The Regal Sportback GS has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the G70.
