2008 Infiniti G37

Safety Comparison

The 1 Series offers optional BMW Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to get driving directions, 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 G37 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies.

Both the 1 Series and the G37 have standard driver and passenger frontal airbags, front side-impact airbags, head airbags, front seatbelt pretensioners, four wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

The 1 Series’ corrosion warranty is 5 years longer than the G37’s (12 vs. 7 years).

BMW pays for scheduled maintenance on the 1 Series for 4 years and 50,000 miles. BMW will pay for oil changes, tire rotation, lubrication and any other scheduled maintenance. Infiniti doesn’t pay scheduled maintenance for the G37.

There are over 2 times as many BMW dealers as there are Infiniti dealers, which makes it much easier to get service under the 1 Series’ warranty.

Engine Comparison

The 135i’s standard 3.0 turbo 6 cyl. produces 30 lbs.-ft. more torque (300 vs. 270) than the G37’s 3.7 DOHC V6.

As tested in Road & Track the 135i is faster than the Infiniti G37 (manual transmissions tested):

Tires and Wheels Comparison

The 135i’s 215/40R18 front and 245/35R18 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) which provides a stiffer sidewall than the G37’s optional 45 series front and 40 series rear tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the 1 Series can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The G37 doesn’t offer run-flat tires.

Suspension and Handling Comparison

The 1 Series’ front to rear weight distribution is more even (50.3% to 49.7%) than the G37’s (54% to 46%). This gives the 1 Series more stable handling and braking.

For better maneuverability, the 1 Series’ turning circle is 1 foot tighter than the G37’s (35.1 feet vs. 36.1 feet).

Chassis Comparison

The BMW 1 Series may be more efficient, handle and accelerate better because it weighs up to about 350 pounds less than the Infiniti G37.

The 1 Series is 11.4 inches shorter than the G37, making the 1 Series easier to handle, maneuver and park in tight spaces.

Passenger Space Comparison

The 1 Series Coupe has .6 inches more front hip room, 2.3 inches more front shoulder room, 2.6 inches more rear headroom, 5.2 inches more rear hip room and 2.3 inches more rear shoulder room than the G37.

Cargo Capacity Comparison

The 1 Series Coupe has a much larger trunk than the G37 (10 vs. 7.4 cubic feet).

The 1 Series’ standard folding rear seats are split to accommodate bulky cargo. The G37’s standard single piece folding rear seat is not as flexible; long cargo and a passenger can’t share the rear seat.

Ergonomics Comparison

The 1 Series has a lever hand brake in the console, easy to use while keeping both feet free and not impeding entry and exit. The G37’s foot pedal parking brake is not handy to use as a hill holding device with a manual transmission.

The 1 Series’ 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 G37’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

Heated windshield washer nozzles are standard on the 1 Series to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The G37 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 1 Series offers available headlight washers to keep headlight output high. The G37 doesn’t offer headlight washers.

The 1 Series has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. The G37 has an automatic headlight on/off feature standard only on the Journey/Sport.

The 1 Series offers optional 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 G37 has an automatic rear view mirror, but its side mirrors don’t dim.
