New Toyota Supra and BMW Z4 stock is gone across the United States, with no remaining inventory for buyers who left it until the end of the run. Production of the two mechanically related sports cars ended in March at Magna Steyr's plant in Graz, Austria, the contract manufacturer that built both.
The pair shared a platform, engines and much of their engineering, but were positioned very differently: the Supra was a coupe only, while the Z4 was a soft-top roadster. Depending on the market, both rear-wheel-drive two-seaters came with four- or six-cylinder engines and a choice of six-speed manual or eight-speed automatic gearboxes.
Slow sales preceded the shutdown
Neither car was a volume seller. Toyota delivered 2,953 Supras in the US in 2025 and BMW moved 2,113 Z4s over the same period. Both companies had already decided to discontinue the models, and that weak demand suggests the decision was not taken reluctantly.
The upside for buyers is that the two-door, combustion-engined sports car field is thinning fast. Porsche has changed its plans and will not bring back the 718 Boxster and Cayman with petrol engines, which leaves the Nissan Z and the Mazda MX5 among the remaining affordable options, with a new MX5 generation due in the coming years.
Toyota keeps the Supra name alive
Toyota has made clear it remains committed to the Supra nameplate, so the current generation is not the end of the road. The company has not announced a timeline or technical details for a successor, and it has not said when the next Supra will arrive or what will power it.
Its public statements suggest another generation is on the table, and it could depart from the BMW-derived approach: the next Supra may use a Toyota-developed powertrain rather than BMW engineering. A new model would slot naturally into Toyota's expanding GR performance sub-brand, alongside the GR Yaris, GR Corolla and GR86.
Toyota has also been signalling a return for the mid-engined MR2, and it recently confirmed the Celica is coming back in WRC. If those projects reach production in road-legal form, Toyota would have one of the more appealing sports car line-ups on sale.
No replacement Z4 in sight
BMW has said nothing about developing a Z4 replacement and has stayed tight-lipped about another roadster, with no indication a new Z model is in the pipeline. An i4 Convertible is in the works, but its four seats, larger footprint and all-electric powertrain mean it will not be a direct substitute.
For now the 4 Series Convertible is the closest open-top alternative BMW offers, a considerably different proposition that is expected to stay on sale until the end of the decade with M Performance and full M versions using inline-six engines. The 2 Series and M2 are closer in size to the Z4 but come strictly as coupes.
The result is a lopsided picture: Toyota has publicly kept the door open for its sports car, while BMW has left the roadster's future unspoken. For anyone shopping in this segment now, the practical choice is remaining stock elsewhere or waiting on a Supra that has been promised but not yet specified.
