That's a whopping $65,143 on average. Meanwhile, a Kia Rio only loses $21 in the first year of ownership.

It's no secret that new cars take a big hit on value once they leave the dealership lot. Some take bigger hits than others. Then there's the Mercedes-Benz EQS. The luxury EV loses a whopping 48.7 percent of its average new price after just one year of ownership, according to a study published by iSeeCars. That equates to $65,143—essentially the same as writing off an entire E-Class.

It's not the only electric vehicle on iSeeCar's list of fastest-depreciating cars, either. Five of the top ten vehicles in the study are EVs, starting with the Nissan Leaf in second place. It only loses $15,786 on average, but with a considerably lower starting price, we're still talking about a 45 percent drop. Jaguar holds the distinction of having the highest-depreciating combustion vehicle with the F-Pace in third, losing $28,555, or 35.4 percent of its value. Alfa Romeo isn't far behind with the Giulia at 33.4 percent, dropping $16,297 on average. The Kia EV6 nabs fifth 33.3 percent, losing $18,081 on average.




What about vehicles that aren't taking such a financial beating? The study shows lots of love for hybrid vehicles, but it's the plucky Kia Rio that turned our heads. It seems folks in the US still want an inexpensive combustion-powered subcompact, because it only lost $21 on average after one year of use. It's a drop of just 0.1 percent, meaning a lightly used Rio still fetches a nearly-full sticker price. The fact that it was dropped from Kia's lineup for 2024 could be a factor, too.
