Compare the2024 Volkswagen Jetta GLIVS 2023 Lexus IS

To help make backing out of a parking space safer, the Jetta GLI has standard Rear Traffic Alert with automatic braking, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Rear Cross-Traffic Braking costs extra on the IS.

Both the Jetta GLI and the IS have standard driver and passenger frontal airbags, front side-impact 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, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Volkswagen Jetta GLI is safer than the Lexus IS:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Volkswagen Jetta GLI is safer than the Lexus IS:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The Jetta GLI’s corrosion warranty is 1 year longer than the IS’ (7 vs. 6 years).

Volkswagen pays for scheduled maintenance on the Jetta GLI for 1 year and 10,000 miles longer than Lexus pays for maintenance for the IS (2/20,000 vs. 1/10,000).

There are almost 3 times as many Volkswagen dealers as there are Lexus dealers, which makes it much easier should you ever need service under the Jetta GLI’s warranty.

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

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

On the EPA test cycle the Jetta GLI gets better mileage than the IS:

In heavy traffic or at stoplights the Jetta GLI Automatic’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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The IS doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Volkswagen Jetta GLI uses regular unleaded gasoline (premium recommended for maximum performance). The IS requires premium, which can cost on average about 82.8 cents more per gallon.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Volkswagen Jetta GLI higher (7 out of 10) than the Lexus IS (5). This means the Jetta GLI produces up to 8 pounds less smog-producing pollutants than the IS every 15,000 miles.

The Jetta GLI offers a manual transmission for better acceleration, control and sportiness. The IS doesn’t offer a manual transmission.

The Jetta GLI offers an optional 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 doesn’t offer an SMG.

For better stopping power the Jetta GLI’s standard brake rotors are larger than those on the IS:

The Jetta GLI handles at .95 G’s, while the IS 500 Performance pulls only .89 G’s of cornering force in a Car and Driver skidpad test.

The Volkswagen Jetta GLI may be more efficient, handle and accelerate better because it weighs about 450 to 550 pounds less than the Lexus IS.

The Jetta GLI has 3.7 cubic feet more passenger volume than the IS (93.9 vs. 90.2).

The Jetta GLI has .3 inches more front headroom, .3 inches more rear headroom, 5.2 inches more rear legroom and .6 inches more rear shoulder room than the IS.

The Jetta GLI has a much larger trunk than the IS (14.1 vs. 10.8 cubic feet).

The power windows standard on both the Jetta GLI and the IS have locks to prevent small children from operating them. When the lock on the Jetta GLI is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The IS prevents the driver from operating the other windows just as it does the other passengers.

The Jetta GLI’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 IS’ cruise control switches are unlit, making them difficult to find at night and operate safely.

The Jetta GLI’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’ standard manually variable intermittent wipers have to be constantly adjusted.

To shield the driver’s vision over a larger portion of the windshield and side window, the Jetta GLI has a standard extendable sun visor. The IS doesn’t offer extendable visors.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Volkswagen Jetta GLI has a standard wireless phone charging system (Qi) in the center console. The IS doesn’t offer wireless personal charging.

The Volkswagen Jetta outsold the Lexus IS by 79% during 2022.
