The CLA offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The IS Series only offers a rear monitor and front and rear parking sensors that beep. That doesn’t help with obstacles to the sides.

The CLA’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The IS Series doesn’t offer a driver alert monitor.

Both the CLA and the IS Series have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive, lane departure warning systems, blind spot warning systems and rear cross-path warning.

There are over 59 percent more Mercedes dealers than there are Lexus dealers, which makes it much easier should you ever need service under the CLA’s warranty.

A hardened steel chain, with no maintenance needs, drives the camshafts in the CLA’s engine. A rubber cam drive belt that needs periodic replacement drives the IS Series’ camshafts. If the IS Series’ belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

In heavy traffic or at stoplights the CLA’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The IS Series doesn’t offer an automatic engine start/stop system.

The CLA offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The IS Series doesn’t offer an SMG or a conventional manual transmission.

For better ride, handling and brake cooling the CLA has standard 18-inch wheels. Smaller 17-inch wheels are standard on the IS Series. The CLA’s optional 19-inch wheels are larger than the 18-inch wheels optional on the IS Series.

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

The CLA’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The IS Series doesn’t offer drift compensation steering.

For better handling and stability, the track (width between the wheels) on the CLA is 3.1 inches wider in the front and 2.1 inches wider in the rear than on the IS Series.

The Mercedes CLA may be more efficient, handle and accelerate better because it weighs about 200 to 400 pounds less than the Lexus IS Series.

The CLA offers an optional 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 IS Series doesn’t offer a heads-up display.

The CLA’s power parking brake sets with one touch and releases with one touch or automatically. The IS Series has a lever-type parking brake that has to be strenuously raised to engage properly. It has to be lifted up more and a button depressed to release it.

The CLA’s 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 IS Series’ standard manually variable intermittent wipers have to be constantly adjusted.

The CLA’s optional Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The IS Series doesn’t offer an automated parking system.
