The 2 Series Gran Coupe has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Civic Si doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The 2 Series Gran Coupe offers optional Active Park Distance Control that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The Civic Si doesn’t offer backup collision prevention brakes.

The 2 Series Gran Coupe offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Civic Si doesn’t offer all-wheel drive.

The 2 Series Gran Coupe has standard BMW Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Civic Si doesn’t offer a GPS response system, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the 2 Series Gran Coupe and the Civic Si have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.

The BMW 2 Series Gran Coupe weighs 441 to 653 pounds more than the Honda Civic Si. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.

Warranty

The 2 Series Gran Coupe comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Civic Si’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The 2 Series Gran Coupe’s corrosion warranty is 7 years longer than the Civic Si’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the 2 Series Gran Coupe for 1 year and 12000 miles longer than Honda pays for maintenance for the Civic Si (3/36,000 vs. 2/24,000).

Reliability

J.D. Power and Associates rated the 2 Series Gran Coupe third among small premium cars in their 2023 Initial Quality Study. The Civic Si isn’t in the top three in its category.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Honda vehicles. J.D. Power ranks BMW above average in long-term dependability. With 5 more problems per 100 vehicles in the first three years of ownership, Honda is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that BMW vehicles are more reliable than Honda vehicles. Consumer Reports ranks BMW third in overall reliability. Honda is ranked fifth.

Engine

The 228i Gran Coupe’s standard 2.0 turbo 4-cylinder produces 28 more horsepower (228 vs. 200) and 66 lbs.-ft. more torque (258 vs. 192) than the Civic Si’s 1.5 turbo 4-cylinder. The M235i xDrive Gran Coupe’s standard 2.0 turbo 4-cylinder produces 102 more horsepower (302 vs. 200) and 140 lbs.-ft. more torque (332 vs. 192) than the Civic Si’s 1.5 turbo 4-cylinder.

Fuel Economy and Range

Regenerative brakes improve the 2 Series Gran Coupe’s fuel efficiency by converting inertia back into energy instead of wasting it. The Civic Si doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the 2 Series Gran 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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Civic Si doesn’t offer an automatic engine start/stop system.

Transmission

The 2 Series Gran Coupe has a standard automatic transmission, for driver comfort, especially in the city. The Civic Si doesn’t offer an automatic transmission.

To facilitate fast shifting and allow the driver to focus on the road, the 2 Series Gran Coupe offers an optional up-shift light to indicate when the engine is approaching redline. The Civic Si doesn’t offer an up-shift light.

The 2 Series Gran Coupe’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Civic Si doesn’t offer launch control.

Brakes and Stopping

For better stopping power the 2 Series Gran Coupe’s brake rotors are larger than those on the Civic Si:

	2 Series Gran Coupe	M235i xDrive Gran Coupe	Civic Si
Front Rotors	13 inches	14.2 inches	12.3 inches
Rear Rotors	11.8 inches	13 inches	11.1 inches

The 2 Series Gran Coupe’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Civic Si are solid, not vented.

The 2 Series Gran Coupe stops shorter than the Civic Si:

	2 Series Gran Coupe	Civic Si
70 to 0 MPH	156 feet	160 feet	Car and Driver
60 to 0 MPH	108 feet	110 feet	Motor Trend
60 to 0 MPH (Wet)	143 feet	147 feet	Consumer Reports

Tires and Wheels

The 2 Series Gran Coupe’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Civic Si’s 40 series tires.

For better ride, handling and brake cooling the 2 Series Gran Coupe offers optional 19-inch wheels. The Civic Si’s largest wheels are only 18-inches.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the 2 Series Gran Coupe can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Civic Si doesn’t offer run-flat tires.

The 2 Series Gran Coupe has a standard space-saver spare (not available on M235i) so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Civic Si; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

The 2 Series Gran Coupe has standard front and rear gas-charged shocks for better control over choppy roads. The Civic Si’s suspension doesn’t offer gas-charged shocks.

The 2 Series Gran 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 Civic Si’s suspension doesn’t offer adjustable shock absorbers.

The M235i xDrive Gran Coupe executes Motor Trend’s “Figure Eight” maneuver quicker than the Civic Si (25.8 seconds @ .71 average G’s vs. 26.3 seconds @ .67 average G’s).

For better maneuverability, the 2 Series Gran Coupe’s turning circle is .7 feet tighter than the Civic Si’s (37.4 feet vs. 38.1 feet).

Chassis

The 2 Series Gran Coupe is 5.5 inches shorter than the Civic Si, making the 2 Series Gran Coupe easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The 2 Series Gran Coupe has a larger trunk than the Civic Si (15.1 vs. 14.4 cubic feet).

To allow full utilization of available cargo room, the 2 Series Gran Coupe’s trunk lid uses concealed beam hinges that don’t intrude into the trunk. Its intrusive beam hinge reduces the Civic Si’s useful trunk space.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the 2 Series Gran offers cargo security. The Civic Si’s non-lockable remote release defeats cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the 2 Series Gran Coupe. The Civic Si doesn’t offer locking storage for small valuables.

To make loading groceries and cargo easier when your hands are full, the 2 Series Gran Coupe’s available trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The Civic Si 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 2 Series Gran Coupe uses gas struts to support the hood for easier service access. The Civic Si 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.

J.D. Power and Associates surveys of service recipients show that BMW service is better than Honda. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 31% lower rating, Honda is ranked 25th.

Ergonomics

The 2 Series Gran Coupe offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Civic Si doesn’t offer a remote starting system.

When two different drivers share the 2 Series Gran Coupe, the memory system makes it convenient for both. Each keyless remote activates different, customized memories for the driver’s seat position, outside mirror angle, climate settings and radio stations. The Civic Si doesn’t offer a memory system.

The 2 Series Gran Coupe offers an optional heads-up display that projects speed, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Civic Si doesn’t offer a heads-up display.

The power windows standard on both the 2 Series Gran Coupe and the Civic Si have locks to prevent small children from operating them. When the lock on the 2 Series Gran Coupe is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Civic Si prevents the driver from operating the other windows just as it does the other passengers.

The 2 Series Gran Coupe’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Civic Si’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the 2 Series Gran Coupe the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Civic Si can only close the windows from inside the vehicle, with the ignition on.

The 2 Series Gran Coupe’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Civic Si’s passenger power window switches are unlit, making them difficult to find at night and operate safely.

The 2 Series Gran 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 Civic Si’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

To help drivers see further while navigating curves, the 2 Series Gran Coupe offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Civic Si doesn’t offer cornering lights.

When the 2 Series Gran 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 Civic Si’s mirror doesn’t automatically adjust for backing.

The 2 Series Gran Coupe’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Civic Si doesn’t offer the luxury of automatic dimming mirrors.

The 2 Series Gran Coupe offers optional heated front seats, which keep the driver and front passenger extremely comfortable in the winter. Heated seats aren’t available in the Civic Si.

On extremely cold winter days, the 2 Series Gran Coupe’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Civic Si doesn’t offer a heated steering wheel.

The 2 Series Gran 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 Civic Si doesn’t offer dual zone air conditioning.

Both the 2 Series Gran Coupe and the Civic Si offer rear vents. For greater rear passenger comfort, the 2 Series Gran Coupe has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Civic Si doesn’t offer rear air conditioning vents, only heat vents.

To direct the driver from any location to a given street address, a GPS navigation system is standard on the 2 Series Gran Coupe. The 2 Series Gran Coupe’s navigation system also has a real-time traffic update feature that offers alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Civic Si doesn’t offer a navigation system.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW 2 Series Gran offers an optional wireless phone charging system (Qi) in the center console. The Civic Si doesn’t offer wireless personal charging.
