Compare the2027 Nissan Sentra VS 2027 Mercedes CLA Hybrid

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Sentra are reminded to check the back seat if they opened the rear door before starting out. The CLA Hybrid doesn’t offer a back seat reminder.

The Nissan Sentra has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The CLA Hybrid doesn’t offer a front passenger side knee airbag.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Nissan Sentra achieved a “Acceptable” rating - the second highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Mercedes CLA Hybrid has not been tested.

Both the Sentra and the CLA Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, 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, driver alert monitors and available around view monitors.

The Nissan Sentra has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2026 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, a “Good” score in the revised pedestrian crash prevention test, and an “Acceptable” score in the revised vehicle-to-vehicle crash prevention test. The CLA Hybrid has not yet been evaluated by the IIHS for 2026.

Nissan’s powertrain warranty covers the Sentra 1 year and 10,000 miles longer than Mercedes covers the CLA Hybrid. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the CLA Hybrid ends after only 4 years or 50,000 miles.

There are almost 3 times as many Nissan dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Sentra’s warranty.

J.D. Power and Associates rated the Sentra first among compact cars in their 2025 Initial Quality Study. The CLA Hybrid isn’t in the top three in its category.

J.D. Power and Associates’ 2025 Initial Quality Study of new car owners surveyed provide the statistics that show that Nissan vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks Nissan second in initial quality, above the industry average. With 41 more problems per 100 vehicles, Mercedes is ranked 21st, below the industry average.

J.D. Power and Associates’ 2025 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Nissan vehicles are more reliable than Mercedes With 28 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Nissan higher than Mercedes.

From surveys of all its subscribers, Consumer Reports’ March 2026 Auto Issue reports that Nissan vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Nissan 13 places higher in reliability than Mercedes.

Both the Sentra and CLA Hybrid have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stoplights and heavy traffic. The Sentra has a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily.

To lower fuel costs and make buying fuel easier, the Nissan Sentra uses regular unleaded gasoline. The CLA Hybrid requires premium, which can cost on average about 84.9 cents more per gallon.

The Sentra has a gallon more fuel capacity than the CLA Hybrid (12.4 vs. 11.4 gallons), for longer range between fill-ups.

The Sentra has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The CLA Hybrid doesn’t offer a cap-less fueling system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Nissan Sentra higher (7 out of 10) than the Mercedes CLA Hybrid (6). This means the Sentra produces up to 1.1 pounds less smog-producing pollutants than the CLA Hybrid every 15,000 miles.

The Sentra has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The CLA Hybrid doesn’t offer a CVT.

The Sentra has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The CLA Hybrid doesn’t offer vehicle monitored tire inflation.

For better maneuverability, the Sentra’s turning circle is 2 feet tighter than the CLA Hybrid’s (34.8 feet vs. 36.8 feet).

The Nissan Sentra may be more efficient, handle and accelerate better because it weighs about 400 to 500 pounds less than the Mercedes CLA Hybrid.

The Sentra is 4.6 inches shorter than the CLA Hybrid, making the Sentra easier to handle, maneuver and park in tight spaces.

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

Because it has more passenger and cargo room, the EPA rates the Sentra a Mid-size car, while the CLA Hybrid is rated a Compact.

The Sentra has 5.1 cubic feet more passenger volume than the CLA Hybrid (96.1 vs. 91).

The Sentra has 2.4 inches more front legroom, 1.2 inches more rear legroom and 1.1 inches more rear shoulder room than the CLA Hybrid.
