The G70 Prestige/Sport has a standard 360-degree Multi-view Monitor to allow the driver to see objects all around the vehicle on a screen. The AMG CLA 45 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.

To help make backing safer, the G70’s 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 AMG CLA 45 doesn’t offer a cross-path warning system.

Both the G70 and the AMG CLA 45 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, driver alert monitors and available all wheel drive.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the G70 its highest rating: “Top Pick Plus” for 2019, a rating granted to only 55 vehicles tested by the IIHS. The AMG CLA 45 has not been tested, yet.

To make loading and unloading groceries and cargo easier, especially for short adults, the G70 3.3T Prestige/3.3T Sport has a standard power trunk, which opens and closes automatically by pressing a button or just by waiting momentarily behind the back bumper, completely leaving your hands free. The AMG CLA 45 doesn’t offer a power trunk.

The G70 uses gas struts to support the hood for easier service access. The AMG CLA 45 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 engine in the G70 is mounted longitudinally (North-South), instead of sideways, as in the AMG CLA 45. This makes it easier to service and maintain, because the accessory belts are in front.

The G70 Prestige/Sport has a standard heads-up display that projects speed 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 AMG CLA 45 doesn’t offer a heads-up display.

The G70’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 AMG CLA 45’s cruise control switches are unlit, making them difficult to find at night and operate safely.

While driving with high beams on, sensitive light sensors standard on the G70 detect other vehicles which could be blinded and automatically switch to low beams. The AMG CLA 45 doesn’t offer automatic dimming high beams.

To help drivers see further while navigating curves, the G70 3.3T Elite/Prestige/Sport has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The AMG CLA 45 doesn’t offer cornering lights.

Both the G70 and the AMG CLA 45 offer available heated front seats. The G70 Prestige/Sport also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the AMG CLA 45.

Standard air-conditioned seats in the G70 3.3T/2.0T Manual/Prestige/Sport keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The AMG CLA 45 doesn’t offer air-conditioned seats.

On extremely cold winter days, the G70 3.3T Elite/Prestige/Sport’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The AMG CLA 45 doesn’t offer a heated steering wheel.
