The Lexus LFA is powered by a 72-degree bank angle V10 engine equipped with Dual VVT-i carrying the "1LR-GUE" designation with a maximum output of delivered at 8,700 rpm. Its maximum torque output of arrives at 6,800 rpm, 90 percent of which is available from 3,700 rpm. The engine redlines at 9,000 rpm, but with a fuel cutoff set at 9,500 rpm, and is constructed using forged aluminum pistons, forged titanium connecting rods, and solid titanium valves. The V-angle of the LFA's V-10 engine is set to 72-degrees to fully balance the firing force from the pistons. This 72-degree angle allows for even firing from the pistons without the use of a split-journal crankshaft, thus improving engine efficiency as well as lowering the overall weight. Dry sump lubrication prevents engine oil starvation through high-speed corners and lowers the engine's center of mass. Air is fed directly from beneath the hood through a visible slit passing into a dual-stage variable intake manifold and then into ten individual throttle bodies before finally exiting from a dual-stage titanium muffler.
