Safety

To maximize occupant safety, the front seat shoulder belts of the BMW 4 Series Coupe have pretensioners to eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Toyota Supra doesn’t offer pretensioners.

The 4 Series Coupe offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Supra doesn’t offer all-wheel drive.

The 4 Series Coupe offers an optional Side and Top View Cameras to allow the driver to see objects all around the vehicle on a screen. The Supra only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the 4 Series Coupe and the Supra have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.

Warranty

The 4 Series Coupe comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Supra’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

The 4 Series Coupe’s corrosion warranty is 7 years longer than the Supra’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the 4 Series Coupe for 1 year and 11000 miles longer than Toyota pays for maintenance for the Supra (3/36,000 vs. 2/25000).

Reliability

J.D. Power and Associates rated the 4 Series Coupe second among compact premium cars in their 2019 Initial Quality Study. The Supra isn’t in the top three in its category.

Fuel Economy and Range

The 4 Series Coupe has 2.1 gallons more fuel capacity than the Supra (15.8 vs. 13.7 gallons), for longer range between fill-ups.

Transmission and Drivetrain

The 4 Series Coupe offers a manual transmission for better acceleration, control and fuel economy. The Supra doesn’t offer a manual transmission.

All wheel drive, available in the 4 Series Coupe, provides the best traction for acceleration in wet, dry, and icy conditions. In corners, all wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The Toyota Supra is not available with all wheel drive.

Brakes and Stopping

For better stopping power the 440i Coupe M Sport’s front brake rotors are larger than those on the Supra:

Tires and Wheels

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the 4 Series Coupe can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Supra doesn’t offer run-flat tires.

Suspension and Handling

For a smoother ride and more stable handling, the 4 Series Coupe’s wheelbase is 13.4 inches longer than on the Supra (110.6 inches vs. 97.2 inches).

Passenger Space

The 4 Series Coupe has standard seating for 4 passengers; the Supra can only carry 2.

The 4 Series Coupe has 39 cubic feet more passenger volume than the Supra (90 vs. 51).

The 4 Series Coupe has 1.5 inches more front headroom and .9 inches more front shoulder room than the Supra.

Cargo Capacity

The 4 Series Coupe has a much larger trunk than the Supra (15.7 vs. 10.2 cubic feet).

To make loading groceries and cargo easier when your hands are full, the 4 Series Coupe’s available trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The Supra doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Ergonomics

Heated windshield washer nozzles are standard on the 4 Series Coupe to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Supra doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The 4 Series Coupe offers available headlight washers to keep headlight output high. The Supra doesn’t offer headlight washers.

To help drivers see further while navigating curves, the 4 Series Coupe offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Supra doesn’t offer cornering lights.

The 4 Series Coupe’s sun-visors swivel front-to-side to block glare from the side windows. The Supra’s visors are fixed into the windshield header.

A power rear sunshade is optional in the 4 Series Coupe to help block heat and glare for the rear passengers. The Supra doesn’t offer a rear sunshade.

On extremely cold winter days, the 4 Series Coupe’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Supra doesn’t offer a heated steering wheel.

The 4 Series Coupe’s standard GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Supra’s available navigation system doesn’t offer real-time traffic updates.

The 4 Series Coupe’s optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Supra doesn’t offer an automated parking system.

Model Availability

The BMW 4 Series comes in coupe, convertible and four door hatchback bodystyles; the Toyota Supra isn’t available as a convertible or four door.
