Safety Comparison

The ELR’s optional front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The 4 Series Coupe doesn’t offer pre-crash pretensioners.

For enhanced safety, the Cadillac ELR’s rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The BMW 4 Series Coupe doesn’t offer height adjustable seat belts.

To help make backing safer, the ELR’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The 4 Series Coupe doesn’t offer a cross-path warning system.

Both the ELR and the 4 Series Coupe have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

Cadillac’s powertrain warranty covers the ELR 2 years and 20,000 miles longer than BMW covers the 4 Series Coupe. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the 4 Series Coupe ends after only 4 years or 50,000 miles.

There are over 4 times as many Cadillac dealers as there are BMW dealers, which makes it much easier should you ever need service under the ELR’s warranty.

Reliability Comparison

The Cadillac ELR’s engine uses a cast iron block for durability, while the 4 Series Coupe’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

The 4 Series Coupe’s redline is at 7000 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The ELR has a 4800 RPM redline.

J.D. Power and Associates’ 2013 Initial Quality Study of new car owners surveyed provide the statistics that show that Cadillac vehicles are better in initial quality than BMW vehicles. J.D. Power ranks Cadillac 13th in initial quality, above the industry average. With 6 more problems per 100 vehicles, BMW is ranked 18th, below the industry average.

J.D. Power and Associates’ 2013 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Cadillac vehicles are more reliable than BMW vehicles. J.D. Power ranks Cadillac 14th in reliability. With 5 more problems per 100 vehicles, BMW is ranked 16th.

Engine Comparison

The ELR’s 1.4 DOHC 4 cyl. hybrid produces 142 lbs.-ft. more torque (400 vs. 258) than the 428i Coupe’s standard 2.0 turbo 4 cyl. The ELR’s 1.4 DOHC 4 cyl. hybrid produces 100 lbs.-ft. more torque (400 vs. 300) than the 435i Coupe’s standard 3.0 turbo 6 cyl.

Fuel Economy and Range Comparison

On the EPA test cycle the ELR gets better fuel mileage on its electric motor alone than the 428i Auto RWD Auto (85 city/80 hwy MPGe vs. 23 city/33 hwy).

On the EPA test cycle the ELR gets better fuel mileage running its gasoline engine than the 428i Auto RWD Auto (31 city/35 hwy vs. 23 city/33 hwy).

The ELR can drive on battery power alone for up to 37 miles. The 4 Series Coupe must run its internal combustion engine to move.

Tires and Wheels Comparison

For better traction, the ELR has larger tires than the 4 Series Coupe (245/40R20 vs. 225/50R17). The ELR’s tires are larger than the largest tires available on the 4 Series Coupe (245/40R20 vs. 225/40R19).

The ELR’s tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the 4 Series Coupe’s standard 50 series tires.

For better ride, handling and brake cooling the ELR has standard 20-inch wheels. Smaller 17-inch wheels are standard on the 4 Series Coupe. The 4 Series Coupe’s largest wheels are only 19-inches.

Suspension and Handling Comparison

For better handling and stability, the track (width between the wheels) on the ELR is 1.3 inches wider in the front than on the 4 Series Coupe.

Chassis Comparison

The front grille of the ELR uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The 4 Series Coupe doesn’t offer active grille shutters.

The ELR uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The 4 Series Coupe doesn’t offer active noise cancellation.

Ergonomics Comparison

The ELR has a standard 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 4 Series Coupe doesn’t offer a remote starting system.

The ELR’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The 4 Series Coupe doesn’t offer an easy entry system.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the ELR has standard extendable sun visors. The 4 Series Coupe doesn’t offer extendable visors.
