A detailed look at how two of Australia's most popular Sedans compare on price, running costs, safety, and everyday livability.
Specifications and pricing correct at time of publishing. Prices are RRP before on-road costs unless stated otherwise. Always confirm with the manufacturer or dealer before purchasing.
Price Breakdown
The Kia EV4 starts from $59,190 before on-road costs, while the Mercedes-Benz C-Class opens at $76,900. That makes the Kia EV4 the more affordable entry point by $17,710.
Once you factor in stamp duty, registration, CTP insurance, and dealer delivery, expect to add roughly 8-12% on top of the RRP depending on your state. That puts estimated driveaway prices in the ballpark of $65,109 and $84,590 respectively.
The Kia EV4 qualifies for FBT exemption as an electric vehicle, which can dramatically reduce the effective cost for novated lease buyers. The Mercedes-Benz C-Class, as a petrol model, does not qualify.
Safety Rundown
Both the Kia EV4 and Mercedes-Benz C-Class hold a 5-star ANCAP safety rating. Adult occupant protection scored 84% for the Kia EV4 and 91% for the Mercedes-Benz C-Class.
Where the two diverge is in active safety technology. The Mercedes-Benz C-Class packs more ADAS features with 6 out of 10 key systems fitted, compared to 4 in the Kia EV4.
Both include the essentials: autonomous emergency braking, lane keep assist, adaptive cruise control, a reversing camera.
Feature Showdown
The Kia EV4 features a 12.3-inch touchscreen paired with a 12.3-inch digital dash, while the Mercedes-Benz C-Class gets a 11.9-inch display and 12.3-inch instruments. Apple CarPlay and Android Auto are standard across both.
The Kia EV4 stands out with heated front seats, power tailgate and V2L that you will not find on the Mercedes-Benz C-Class. The Mercedes-Benz C-Class counters with head-up display, panoramic roof and ambient lighting. Which feature set matters more depends on your daily routine and priorities.
Drivetrain
The Kia EV4 uses a Electric Motor producing 150kW and 283Nm of torque, sent through a automatic to a FWD layout. It covers the 0-100km/h sprint in 7.7 seconds.
The Mercedes-Benz C-Class responds with a Petrol making 150kW and 300Nm, paired to a automatic driving the rear wheels. It gets to 100km/h in 7.8 seconds.
Power output is identical on paper, so the difference comes down to tuning, weight distribution, and suspension. In the real-world sprint, the Kia EV4 is 0.1s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
Space & Comfort
The Kia EV4 measures 4,730mm long on a 2,820mm wheelbase, 21mm shorter than the Mercedes-Benz C-Class at 4,751mm (2,865mm wheelbase). The longer wheelbase on the Mercedes-Benz C-Class generally means more rear legroom.
