Lexus LFA A10
Weaknesses, engine ratings and buying advice
Engine Overview
The Lexus LFA A10 is available with 2 engine variants — from 560 to 571 hp.
4.8L V10 in a 72° bank angle — chosen for the sound, not the engineering convenience. Yamaha Motor hand-built each engine, one per day, each with a nameplate of the builder. Titanium connecting rods, titanium valves (including exhaust — unique at the time), DLC-coated rocker arms. Result: 0 to 9,000 RPM in 0.6 seconds — the tachometer had to be digital because no needle could keep up (Polyphony Digital helped design it). Yamaha Corporation tuned the intake manifold like an instrument, Sango shaped the titanium exhaust using vocal formant analysis of the human voice. Dry sump with 14.8 quarts, oil changes are a two-stage affair. Weighs less than Toyota's 3.5L V6. Hiromu Naruse, the chief test driver who pushed the LFA to perfection, died in June 2010 testing a Nürburgring prototype — just as series production began.
- !! ASG Actuator Wear — Rough Shifting from 80,000 km
The automated single-clutch gearbox (Aisin ASG) develops actuator wear. Shifting becomes unpredictable with warning light. Lexus deliberately chose no DCT — the ASG was meant to feel like a manual.
Symptoms: Rough gear changes, delayed clutch engagement, transmission warning light, unpredictable shifts in city driving - ! Dry Sump Oil Change — Complex and Expensive from 15,000 km
Two-stage oil change with 14.8 quarts Mobil 1 5W-50. Carbon fiber undertray must be partially removed. Only LFA-certified Lexus dealers can perform service.
Symptoms: No symptoms — regular service item. Interval adherence critical on high-revving naturally aspirated engine. - ! Oil Pump Internal Seal — Complex Access
Internal oil pump seal may develop a leak. Access requires engine removal or transmission tube disassembly. Documented case at LFA Centre of Excellence Cologne.
Symptoms: Oil loss at lower engine area, oil pressure warning possible, spots under car after standing
