Lamborghini Unleashes The 217mph Sian Roadster That Inspired Tecnomar The 4,000hp Speedboat

Billionaires, Instagram rich kids and anyone else with a spare £6million in the bank can now have a matching Lamborghini for the road and water.

While many businesses have been hammered by the coronavirus lockdown, the adored Italian supercar maker has been busy, launching not only a superyacht but a new hypercar that inspired the boat's design.

This latest model in the flamboyant vehicle maker's arsenal is the Sian Roadster - a V12 hybrid powertrain with 808bhp, a top speed of 217mph and, like its new speedboat, no roof.


While there will be 63 'Tecnomar for Lamborghini 63' superyachts produced, the Sian Roadster is rarer.

Just 19 are being produced, all of them with an open cockpit, and will cost in the region of $3.7million (£3million), which is the rumoured price of the hard-top coupe version revealed last year (of which 63 will be made, like the boat).

But there's no need for you to go raiding your savings account just yet, as all 19 of them have been pre-ordered and paid for by a select few of Lamborghini's well-heeled aficionados who have already been given a sneak preview of the extreme vehicle.


At the heart of the Sian Roadster is Lamborghini’s ferocious 6.5-litre V12 - the motor used in the existing Aventador range.

However, for this limited-edition creation, there's the addition of titanium intake valves and a new exhaust that boosts power to 774bhp - a healthy increase on the 740bhp produced by the standard Aventador S.

And for an additional kick of potency, the Sian Roadster gets a supplementary electric motor embedded in the gearbox to wind the total output to 808bhp. That's good for a sprint to 62mph in 2.9 seconds and a hair-messing 217mph top speed.

Rather than incorporating a heavy lithium-ion battery, the Sian instead uses a supercapacitor, which weighs just 34kg when combined with the tiny e-motor.

The benefit is that the electricity storage can be charged and discharged at the same rate, meaning a driver can resupply energy to the system when pressing the brakes and unleash it with the next stab of the throttle pedal.

Performance figures are on par with the Sian coupe, with Lamborghini stating that the deletion of a roof hasn't hampered the dagger-shaped vehicle's aerodynamic efficiency.

At speed, the front splitter, bonnet vent and side intakes swallow the air and distribute it out via the active rear spoiler to increase downforce. 


The cooling vanes at the rear of the car are there to moderate the temperature of the exhaust system when the owner is getting heavy footed with the accelerator.

When heat levels rise, the vanes rotate to provide extra cooling for the exhaust.

'The Sian Roadster encapsulates the spirit of Lamborghini,' explained company boss Stefano Domenicali.

'It is the expression of breathtaking design and extraordinary performance, but most importantly embodies important future technologies.

'The Sian’s innovative hybrid powertrain heralds the direction for Lamborghini super sports cars, and the open-top Sián Roadster affirms a desire for the ultimate lifestyle Lamborghini as we move towards a tomorrow demanding new solutions.'

Much of the styling - which harks back to legendary models like the Muira and Countach - has been retained from the hard-top version, and are the design features lifted for the speedboat that the Italian brand joint-revealed alongside the Italian Sea Group last week.

While the new Sian Roadster gets one V12 engine, the superyacht gets two - though 24-litres in capacity - with a combined power output of 3,945bhp (4,000hp).

They also weigh a massive 2380kg without fluids, which is not only heavier than the Sian but also bulkier than the Lamborghini Urus SUV.

Top speed for the performance boat is claimed to be over 60 knots, which translates to around 70mph, and the first of just 63 examples built will be delivered next year.

Each one is expected to be priced in excess of $3.4million (£2.7million), which makes the boat cheaper than the car it's based on, if reports of the Sian Roadster's asking price are accurate.

If you wanted to drive your matching hypercar to your hyperyacht docked in the local harbour, the combined cost of having both vehicles is in the region of £6million.
