According to website AutoGuide, an unnamed senior executive within Toyota has revealed details of the car, describing it as "twice the car", with a "significantly higher" level of performance.
Along with a reported production run of no more than 100 units, buyers' bank accounts can likely look forward to a red-hot hiding.
The LFA launched in Australia with a price tag of $750,000 - Japan's most expensive offering to date - and all 500 cars were snapped up well before production began in 2010.
This all suggests that a car twice-as-good and five times more exclusive could potentially sell for more than $1.5 million; within (a billionaire's) spitting distance of Veyron money.
Just how far beyond the LFA the new model's styling would go can only be imagined, although the LF-LC concept shown in January could offer a hint.
If the LF-LC’s ‘Advanced Lexus Hybrid Drive System’ were combined with a variant of the LFA’s 412kW V10 engine, it would make a logical halo car for the entire Toyota group and its continued commitment to hybrid electric technology.
A petrol-electric drivetrain would also set the car up as an ideal rival for Porsche’s upcoming 918 supercar.
When (or even if) we'll see the new supercar is another story; from concept through to production, the LFA was nearly 10 years in the making.
