Lexus LFA A10
Weaknesses, engine ratings and buying advice
The Lexus LFA is not an ordinary car but a piece of engineering with genuine legend status. Between 2010 and 2012, only 500 examples of this supercar were built, each one assembled by hand. At its heart sits the 4.8-litre 1LR-GUE V10 producing 412 to 420 kW, co-developed with Yamaha and laid out with a 72-degree bank angle — chosen for its sound rather than pure engineering convenience. Every engine was assembled by hand, one per day, and fitted with a nameplate bearing the builder's signature. The carbon monocoque, the dry-sump lubrication and the famously fast-sweeping rev needle made the LFA an uncompromising exception even when new.
Anyone considering an LFA is moving in the collector market. Values have climbed steadily for years, and the cars change hands rarely and at correspondingly high prices. That also means an LFA is not an everyday car but a collector's piece that wants to be treated and serviced as such. This is exactly where the challenges lie. The dry-sump oil change is involved and expensive. The actuator of the automated manual gearbox (ASG) wears out and then causes rough shifts. The internal oil pump seal can only be reached with considerable disassembly, and inspecting the valvetrain on an engine that revs to 9,000 rpm belongs in experienced hands.
The surrounding hardware demands attention and budget too. A repair to the carbon monocoque quickly runs into five figures. The original Bridgestone RE070R tyres are no longer produced, which complicates tyre choice. The carbon-ceramic brakes tend to squeal and are extremely costly to replace. The adaptive dampers wear and are expensive to renew, the tyre pressure sensors age, and the multiple cooling circuits with their hoses and pumps need regular checking. Just as important: the battery discharges during long periods of standstill, so a trickle charger is practically mandatory. Note also the Takata recall for the passenger airbag inflator.
The honest verdict: the LFA is not a car you judge on reliability or common sense — it is a hand-built work of art with an incomparable V10 voice and guaranteed collector value. Whoever acquires one buys a piece of history, but must budget for specialised maintenance and rare parts. As an investment and a driving experience it is almost without rival; as a practical everyday tool it is thoroughly unsuited — and that is exactly how it was meant to be.
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
