In 2025, automakers are getting sneakier and smarter about where they put their money. That often means sharing engines across brands and body styles that seem completely unrelated. While the enthusiast crowd might sniff out platform-sharing from a mile away, there are some genuinely surprising engine twins hiding in plain sight. Here are a few 2025 cars you probably didn’t know are running the exact same engine under the hood.

Mazda CX-50 and Toyota Corolla Cross Hybrid

Both tout the 2.0L Toyota Hybrid Engine

The outdoorsy, upmarket-feeling Mazda CX-50 Hybrid shares its engine with the far more modest Toyota Corolla Cross Hybrid. Both use Toyota’s M20A-FXS 2.0-liter Atkinson-cycle inline-four with an eCVT and two electric motors. This powertrain makes 196 horsepower in both vehicles. Mazda essentially borrows Toyota’s TNGA hybrid system as part of a broader partnership. It’s especially ironic since Mazda once emphasized its own SkyActiv technology. Now they’re rolling with Toyota’s system, and it works.

Nissan Z and Infiniti Q50 Red Sport 400

They get a 3.0L Twin-Turbo V6

The 2025 Nissan Z may be pitched as a reborn Japanese muscle car, but it runs the same VR30DDTT engine found in Infiniti’s luxury lineup. That includes the Q50 Red Sport 400 and Q60 coupe. 

These cars use the same turbos, same block, and same 400 horsepower. The tuning feels slightly different, but the core hardware is identical. Nissan admitted the budget for a bespoke engine didn’t make sense when the VR30 was already sitting on the shelf.

Jeep Grand Cherokee 4xe and Chrysler Pacifica Plug-In Hybrid

Both have the same 3.0L Twin-Turbo V6

The Jeep Grand Cherokee 4xe uses the same gas engine and hybrid system as the Chrysler Pacifica Plug-In Hybrid. 

Both pack Stellantis’s 2.0-liter GME-T4 turbocharged four-cylinder paired with a plug-in hybrid setup that delivers over 25 miles of electric-only range. One has trail-rated bragging rights. The other is a minivan known for snacks and school runs. But underneath, they share the same heart.

Ford Maverick Hybrid and Lincoln Corsair Grand Touring

They share the 2.5L Atkinson Hybrid

The base Ford Maverick Hybrid uses a 2.5-liter Atkinson-cycle engine that also powers the Lincoln Corsair Grand Touring plug-in hybrid. 

The Maverick comes as a front-wheel drive, non-plug-in workhorse. The Corsair adds all-wheel drive and more power through its plug-in system. Despite the difference in mission and market, the base engine is identical. It’s the same unit running in both a budget pickup and a compact luxury SUV.

BMW X1 xDrive28i and Toyota Supra 2.0 

Both use a 2.0L BMW B48 Turbo-Four engine

You might expect Toyota to borrow BMW bits for the Supra. What’s more surprising is that the same B48 2.0-liter turbo-four offered in the 2025 Toyota Supra 2.0 also powers BMW’s X1 xDrive28i.

This compact crossover is more about comfort and convenience than performance. But it shares its engine with Toyota’s sports coupe. Both versions make 255 horsepower. The torque curves and tuning differ slightly, but it’s the same engine code and same Bavarian bones.

By the way, Supra buyers can also elect a turbocharged 3.0-liter inline-six…but that’s still BMW’s B58 engine.

Automakers love saving development costs by sharing powertrains

These examples show that even enthusiast or premium models often borrow from more humble siblings or cousins. The next time someone tells you their new car is totally different, check under the hood. It might be more familiar than they think.
