This monster of an engine sits quite far back in the bay and is a marvel of compactness. Despite having more displacement, we're told that the LF-A's 4.8-liter engine is actually smaller in size than the 3.5-liter V-6 that powers the IS.
The large intakes that are sculpted into the B and C pillars don't feed air to the engine, which is located at the front of the vehicle. Instead, it appears that they're directing airflow over transmission and oil coolers.
Is it worth $400k? Well, with an ultralight carbon fiber body, a supercar engine, and a suspension taken straight off of a LeMans racer, we think that it's close. But with only 500 of these babies being made, only a select few can be sure.
