The Q5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The GLB doesn’t offer pre-crash pretensioners.

The Q5 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The GLB 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Q5. But it costs extra on the GLB.

To help make backing safer, the Q5’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 GLB doesn’t offer a cross-path warning system.

Both the Q5 and the GLB have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems and around view monitors.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the Q5 the rating of “Top Pick” for 2017, a rating granted to only 202 vehicles tested by the IIHS. The GLB has not been tested, yet.

The Audi Q5’s engines use a cast iron block for durability, while the GLB’s engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than Mercedes vehicles. J.D. Power ranks Audi 8th in reliability, above the industry average. With 10 more problems per 100 vehicles, Mercedes is ranked 13th.

From surveys of all its subscribers, Consumer Reports’ December 2019 Auto Issue reports that Audi vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Audi 7 places higher in reliability than Mercedes.

On the EPA test cycle the Q5 55 TFSI e gets better fuel mileage than the GLB 4MATIC SMG (64 city/66 hwy vs. 23 city/31 hwy).

The Q5 55 TFSI e can drive on battery power alone for up to 26 miles. The GLB must run its internal combustion engine to move.

Regenerative brakes improve the Q5’s fuel efficiency by converting inertia back into energy instead of wasting it. The GLB doesn’t offer a regenerative braking system.

To lower fuel costs and make buying fuel easier, the Audi Q5 uses regular unleaded gasoline (premium recommended for maximum performance). The GLB requires premium, which can cost 20 to 55 cents more per gallon.

The Q5’s standard fuel tank has 2.6 gallons more fuel capacity than the GLB (18.5 vs. 15.9 gallons).

The Q5’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 GLB doesn’t offer launch control.

For better traction, the Q5’s optional tires are larger than the largest tires available on the GLB (255/45R20 vs. 235/55R18).

The Q5’s optional tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the GLB’s optional 50 series tires.
