Regenerative brakes improve the 4 Series Coupe’s fuel efficiency by converting inertia back into energy instead of wasting it. The 370Z doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the 4 Series Coupe’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The 370Z doesn’t offer an automatic engine start/stop system.

Environmental Friendliness

The U.S. Environmental Protection Agency (EPA) certifies the BMW 4 Series Coupe as a “Super Ultra Low Emissions Vehicle” (SULEV). The Nissan 370Z is only certified to “Ultra Low Emissions Vehicle” (ULEV) standards.

Transmission and Drivetrain

The BMW 4 Series Coupe comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the 370Z.

An eight-speed automatic is standard on the BMW 4 Series Coupe, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the 370Z.

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 Nissan 370Z is not available with all wheel drive.

A standard “hill holder” feature keeps the BMW 4 Series Coupe with manual transmission from rolling backwards on a steep slope. The 370Z doesn’t offer a hill holder feature.

Brakes and Stopping

For better stopping power the 440i Coupe M Sport’s front brake rotors are larger than those on the 370Z:

Tires and Wheels

The 4 Series Coupe’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the 370Z’s standard 50 series front tires.

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 370Z doesn’t offer run-flat tires.

Suspension and Handling

The 4 Series Coupe has standard front and rear gas-charged shocks for better control over choppy roads. The 370Z’s suspension doesn’t offer gas-charged shocks.

The 4 Series Coupe offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The 370Z’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the 4 Series Coupe’s wheelbase is 10.2 inches longer than on the 370Z (110.6 inches vs. 100.4 inches).

The 4 Series Coupe’s front to rear weight distribution is more even (50.2% to 49.8%) than the 370Z’s (54.3% to 45.7%). This gives the 4 Series Coupe more stable handling and braking.

The 440i Coupe executes Motor Trend’s “Figure Eight” maneuver quicker than the 370Z (25.5 seconds @ .75 average G’s vs. 25.9 seconds @ .7 average G’s).

Passenger Space

The 4 Series Coupe has standard seating for 4 passengers; the 370Z can only carry 2.

The 4 Series Coupe has 38.4 cubic feet more passenger volume than the 370Z (90 vs. 51.6).

The 4 Series Coupe has 1.6 inches more front headroom and .9 inches more front shoulder room than the 370Z.

Cargo Capacity

The 4 Series Coupe has a much larger trunk than the 370Z (15.7 vs. 6.9 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 370Z doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Servicing Ease

The 4 Series Coupe uses gas struts to support the hood for easier service access. The 370Z uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The 4 Series Coupe has a maintenance free battery for long life without checking the battery’s water level. The 370Z doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.


To help each driver find a more comfortable driving position, the 4 Series Coupe has a telescoping steering wheel. Much better than just a tilt steering wheel or adjustable seat, this allows a short driver to sit further from the steering wheel while maintaining contact with the pedals. The 370Z doesn’t offer a telescoping steering wheel.

When two different drivers share the 4 Series Coupe, the memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, outside mirror angle, climate settings and radio stations. The 370Z doesn’t offer a memory system.

The 4 Series Coupe offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The 370Z doesn’t offer a heads-up display.

The 4 Series Coupe’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The 370Z’s manually variable intermittent wipers have to be constantly adjusted.

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 370Z 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 370Z doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors available for the 4 Series Coupe detect other vehicles which could be blinded and automatically switch to low beams. The 370Z doesn’t offer automatic dimming high beams.

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 370Z doesn’t offer cornering lights.

A power rear sunshade is optional in the 4 Series Coupe to help block heat and glare for the rear passengers. The 370Z doesn’t offer a rear sunshade.

The 4 Series Coupe’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Nissan only offers heated mirrors on the 370Z Sport/Sport Touring/NISMO.

When the 4 Series Coupe is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The 370Z’s mirror doesn’t automatically adjust for backing.

The 4 Series Coupe has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The 370Z has an automatic rear view mirror, but its side mirrors don’t dim.

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 370Z doesn’t offer a heated steering wheel.

The 4 Series Coupe’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The 370Z doesn’t offer dual zone air conditioning.

To keep a safe, consistent following distance, the 4 Series Coupe Automatic offers an optional Active Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The 370Z doesn’t offer an adaptive cruise control.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW 4 Series offers an optional wireless phone charging system (Qi) in the center console. The 370Z doesn’t offer wireless personal charging.

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 370Z doesn’t offer an automated parking system.

Model Availability

The BMW 4 Series comes in coupe, convertible and four door hatchback bodystyles; the Nissan 370Z isn’t available as a convertible or four door.

Economic Advantages

Insurance will cost less for the 4 Series Coupe owner. The Car Book by Jack Gillis rates the 4 Series Coupe with a number “1” insurance rate while the 370Z is rated higher at a number “3” rate.

The 4 Series Coupe will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the 4 Series Coupe will retain 45.76% to 49.08% of its original price after five years, while the 370Z only retains 19.47% to 45.22%.

According to The Car Book by Jack Gillis, the 4 Series Coupe is less expensive to operate than the 370Z because typical repairs cost much less on the 4 Series Coupe than the 370Z, including $231 less for a fuel pump and $175 less for a power steering pump.


The 4 Series Coupe was chosen as one of Car and Driver’s “Top Ten” in 2014. The 370Z has never been a Car and Driver “Top Ten” pick.

The 4 Series Coupe was chosen as one of Automobile Magazine’s “All Stars” in 2014. The 370Z has never been an “All Star.”

The BMW 4 Series outsold the Nissan 370Z by over 9 to one during 2018.
