Gordon Murray’s second supercar, , will be street-legal in the U.S., but making it legally drivable on public roads didn’t come cheap. confirmed that it cost his company $33 million to undergo the testing and development required to meet all emissions and crash standards in the U.S., as reports.

Of course, getting a car through rigorous standards both abroad and in the U.S. is costly. Spending millions of dollars on a single model is not unheard of in order to meet , but carmakers know it’s all part of the process for production models. models, however, are hardly alike to mass-produced vehicles.

Similar to the , the T.33 will be limited to just 100 models, making the emission and crash standard certification much more expensive on a per-model basis. It’s a good thing, then, that selling was easier than making them: Gordon Murray confirmed all models have sold out.

In order to meet all FMVSS, Gordon Murray had to be selective about what the T.33 borrowed from its sibling, , which is not street-legal in the U.S. and can only be brought into the country under a show-or-display provision.

The design of T.33 had to be toned down, taking a milder approach than that of the T.50, which is powered by a naturally aspirated 4.0-liter V12 making 650 horsepower that revs to 12,100 rpm. The T.50 weighs just 2,150 pounds and its cabin has a central driving position for the pilot only.

That was a no-go according to U.S. safety standards, so the T.33 will have a standard two-seat arrangement. Performance is below that of the T.50, but the less extreme is still a supercar: it’ll be powered by the same 4.0-liter Cosworth V12, but will only make 592 hp and 333 lb-ft of torque. The engine will also be slightly less revvy, reaching only 11,100 rpm.

But the T.33 is still a lightweight machine at about 2,400 pounds, so the power penalty to meet U.S. safety regs won’t sting as much. Now that the T.33 has cleared all standards — from crash safety, to drive-by noise, to emissions — it’s likely that when the T.33 finally makes it to U.S. buyers in 2024, the supercar costing $1.9 million can be driven down to the corner store for a Red Bull.

That makes the T.33 look like a downright bargain compared to the T.50, which costs $2.5 million and, yet, won’t be drivable on U.S. roads.
