How does the Lexus LFA rev so fast?

How the Lexus LFA Revs So Fast
The Lexus LFA is able to rev so fast due to several key engineering and design features:
1. Engine Design and Materials: The LFA’s V10 engine is designed with lightweight but strong materials, such as titanium alloy valves and cylinder-shaped, low-inertia valve springs to prevent valve float at high revs. The engine also features lightweight forged pistons designed to cope with high compression ratios.
2. Air and Fuel Management: The LFA’s engine has precise air and fuel management, exceeding existing emission regulations. Its symmetrical dual intake system is tuned to switch from a primary inlet port at low to medium speeds to dual ports at higher revs, boosting breathing efficiency.
3. Digital Rev Counter: The design of the LFA’s engine allowed it to rev so fast that Lexus had to use a special TFT LCD to present the rev changes instead of a physical needle. The physical needle on the rev counter cannot keep up with the rapid rev changes, so a digital gauge was installed.
4. Internal Components: The engine received forged aluminum pistons, forged titanium connecting rods, solid titanium valves, and a three-way titanium exhaust, reducing the weight of the engine’s internals and allowing it to spin up to high revs with lightning efficiency.
These engineering and design features collectively contribute to the Lexus LFA’s ability to rev so quickly, making it a standout feature of this high-performance supercar.

How does the LFA exhaust work?

Up to 3,000rpm, the exhaust valve stays closed, routing the flow through multiple chambers, creating an unobtrusive note. Above 3,000rpm the valve opens, allowing the exhaust to bypass these chambers and flow into a single resonance chamber, before exiting through the stacked trio of tailpipes.

With a 0-60 MPH time of 3.96 seconds, the Lexus RC F Track Edition is the undisputed king of acceleration, reaching a top speed of 176 mph. A tremendous 472 horsepower and 395 lb-ft of torque are produced by the V8 engine.

Why no one bought Lexus LFA?

The Lexus LFA was a two-door sports car that was as immensely stylish as it was powerful. It had a lot of potentials but it was simply too expensive. Toyota famously lost money on each and every one of the 500 LFAs it made despite selling them for an eye-watering $375,000 each.
