The heart of any car is the engine. The combustion system pumps power to everything from the alternator to the wheels themselves. But it's easily forgotten in the grand scheme, especially when it's a vehicle like the Aston Martin Valkyrie.

The automaker recently released some in-depth information about the upcoming super car's engine block. Naturally aspirated, the 6.5-liter V-12 engine can produce over 1,000 horsepower, 546 lb-feet of torque, and 7,000 rpm. Originally called the AM-RB 001, the project was developed alongside Cosworth Engineering.

There's more about the engine than the traditional specs, however. The vehicle is surprisingly efficient. It produces 153.8 hp per liter, which is incredible considering its natural aspiration. It also weighs around 454 pounds, which is below average for any V-12 engine. This is accomplished by having solid aluminum internals with a titanium billet. Aston Martin marks the crankshaft as 50 percent lighter than the 177. Thanks to these endeavors, the Valkyrie is one of the few vehicles that has a power to weight ratio of 1 to 1, if you compare horsepower to kilograms.

The Valkyrie will have a hybrid battery system, but Aston Martin has kept any information about this system a secret at this time. We know that the battery will be supplied by Rimac, at least. They have a reputation for quality. So whatever Aston Martin has planned, it won't be weak.

The Valkyrie will be as rare as it is expensive. With only 150 standard units and 25 track only AMR Pro variants planned for production, each one will cost at least $3.2 million. The wait won't be long, at least. the vehicle is planned for arrival in 2019.
