There are a lot of downsides to buying a brand new car - especially sports cars. Apart from the unknown maintenance troubles that can arise and the obvious high cost compared to used cars, another important factor is the depreciation. New cars are among the most heavily depreciating consumer goods - and the more expensive they are, the harder they get hit.

Nobody likes to see the value of their vehicle disappearing into thin air. However, predicting how much value will be lost exactly is not easy - especially when the car is not even released yet. Luckily for you, we've compiled a list of future cars that, we believe, will depreciate like crazy.

10 2021 Mercedes-Benz S-Class (W223)

Even though Mercedes' flagship sedan still amazes us with its level of tech and refinement, its current generation has been around for more than a few years and is due for a refresh. The 2021 S-Class, known to the enthusiasts as the W223, will not change dramatically in terms of styling, yet under the skin, it will be a completely new car.

Built on an entirely new platform, it's expected to offer mild hybridization, advanced self-driving, and a bunch of other exciting features. What's not so exciting, however, is the prospect of just how much value it will lose. Considering that older S-Class models can be easily picked up for under $20,000, we wouldn't expect anything else to happen to the upcoming one.

9 2021 Alfa Romeo GTV

Since its rebirth, Alfa Romeo seems to have ticked all the lineup boxes that are required from a modern luxury car manufacturer. There is a hatchback, a sports sedan, an SUV - what's missing is, obviously, a stylish coupe.

It's not sure yet whether the historic GTV nameplate will actually return. But if it will, it will probably sit at the top of Alfa's lineup with a rumored 600hp+ hybrid version. It will also most probably commandeer an appropriately high price. And given Alfa's questionable reliability record, we wouldn't be surprised to see this price dwindling just after a couple of years.

8 2022 Mercedes-Benz SL-Class

The current generation of the SL has been around forever, and Mercedes knows what. Over the years, the SL has attracted a reputation that is far from favorable - dated tech, questionable styling, and extremely unreasonable pricing are only a few reasons for that.

This is why the recipe for the upcoming SL is getting rehauled. Expect rear seats, a canvas roof instead of a hardtop, and a much sportier overall character. However, one ingredient that we don't expect to change is the high pricing - way past the $100,000 mark, most likely. And as we've seen with the previous generation SLs, the value doesn't stay in that range for long.

7 2021 Maserati MC20

It seems that Maserati is putting all their money on the upcoming MC20 sports car - both literally and figuratively. They've even developed a whole new engine just for this model! We're not surprised, as the stakes are high - the MC20 is expected to turn the entire struggling Maserati brand around, no easy feat.

Naturally, there is no precise information about the pricing yet, but the estimates range between $150,000 and $200,000 base price. Not very modest for a newcomer model that will most probably be met with serious scrutiny. And Maserati being Maserati, something is telling us that depreciation will not treat the MC20 kindly.

6 2021 Jaguar XJ

Jaguar and losing value go together just like tea and crumpets. And the last generation of the flagship XJ sedan was among the worst offenders - the long-wheelbase version of it lost a whopping 68.9% of its value after 5 years!

And understandably so - while it was a beautiful, exciting car that really stood out in the sea of S-Classes and 7 Series, it just wasn't as good. Jaguar has big plans for the upcoming XJ - namely, it will make it into a fully electric sedan with more than 300 miles of range! And while depreciation hits Jags hard, it hits EVs even harder. Get ready to see some nice deals on used XJs five years down the road.

5 2021 BMW M4

In the neverending battle between BMW M and Mercedes AMG, there is one field where Affalterbach is the clear winner - keeping value. For reasons known or unknown, BMW M cars always seem to depreciate at a faster rate than their rivals.

Judge for yourself: the 2015 vintage of the M4, its first year in the US, can be found nowadays for as little as $30,000. Compare it to the almost-$70,000 MSRP and - oops. We have no reason to believe that the depreciation rates of the upcoming M4 will be any different. As a matter of fact, with that hideous grille, they might be even worse.

4 2021 Audi E-Tron GT

Scheduled to arrive in 2021, the e-tron GT will join Audi's growing lineup of EVs to nicely complement the current e-tron SUV. With its sights clearly aimed at the Tesla Model S, it will share much of its engineering with the Porsche Taycan. One thing it will not share with the Porsche, however, is the ability to actually retain value.

Don't get us wrong - it will most probably be a fantastic car that will sit right between the Taycan and the Model S in terms of pricing and refinement. And while Audis aren't known for catastrophically depreciating, it will be impossible for the e-tron GT to defy the market rules, being an opulent, overengineered luxury sedan and all.

3 2022 Ford Fusion Active

Sometimes, the decisions made by the Ford leadership leave us scratching our heads. They've decided to completely cancel all of their sedans in favor of SUVs - and that includes the Fusion. But then they realized that Americans love the Fusion nameplate too much to just let it go. Enter the Fusion Active, a lifted wagon version of the original sedan that is as similar to it as it is different.

We're not sure what Ford's expectations for the Fusion Active are - in case they missed it, wagons don't sell well in the US, even if they bear a familiar name. Our honest expectations are that approximately 17.5 people in total will buy the Fusion Active, and its value on the used car market will be close to zero.

2 2022 Volvo XC100

Volvo doesn't sell cars, it sells a lifestyle - and you either live it or you don't. Volvos have never been incredibly popular as they've always lacked the oomph that, say, BMW or Jaguar has. But Volvo wishes to change that by releasing a halo car that will showcase their design capabilities and commitment to electric propulsion.

Rumors are, the new flagship will be called the XC100. And while it will most probably have much in common with the current XC90 SUV, it will also have a completely different positioning - and price. But since it will be a Volvo, the depreciation rate will probably stay the same.

1 2022 GMC Hummer EV

GM's decision to revive the infamous Hummer as an EV pickup was met with...polarizing opinions, to say the least. There were some who hated it - to them, Hummer will forever be associated with obnoxiousness and classic American wastefulness. Others took to the idea more enthusiastically - it seems like Hummer is the perfect example of a car that could come back, but strictly as an EV.

So far, GMC is promising us up to 1,000 hp from three electric motors and the 0-60 time as low as 3 seconds. There are no details about the pricing yet, but we expect that the Jaguar scenario will happen to the Hummer as well, as far as depreciation is concerned.
