Lamborghini teases mystery model

Lamborghini has puzzled car fans by announcing it will this week unveil something that's claimed to be 'ahead of its time'.

Posting a teaser on its social media channels over the weekend, the famous Italian car-maker confirmed the date and time of the unveiling but, crucially, didn't say what it would reveal.

This has led the rumour mill to speculate that Lamborghini is about to launch a roadster version of the vehicle that previewed the replacement for the Aventador, the Sian FKP 37 unveiled last year.

The reason some are linking a drop-top Sian to the mystery reveal is that last year Lamborghini's head of design, Mitja Borkert, dubbed the coupe concept a "futuristic icon", mirroring the language used by the car-maker for the latest unveil.

Back in September 2019, the Sian was touted as an advanced four-wheel signpost to the next-generation Aventador, powered by a naturally-aspirated V12 engine hybridised with the aid of supercapacitors rather than batteries.

Highlighting the many benefits of the technology, in this case the supercapacitors boosted the 577kW 6.5-litre V12's power output by 25kW, allowed for a pure-electric range of up to 10km and only increased weight by 32kg – a fraction of the weight of conventional lithium-ion battery cells.

Combined, Lamborghini said this enabled the Sian to hit 100km/h in a blistering 2.8 seconds before topping out at 350km/h.

The same system was also attributed with overcoming the shortcomings of the Aventador's single-clutch automated manual transmission, with the car-maker claiming that its torque-filling properties provide for a more seamless transmission.

Back in 2019, Lamborghini said it would make just 63 examples of the Sian FKP 37, each priced at $3.6 million ($A5.2m). It's thought the roadster will be sold in similar numbers and its price tag will exceed that of the coupe.

Stay tuned as all will be revealed later on Wednesday night in Europe (Thursday, July 9, 2:00am AEST).
