Lamborghini Sian's supercapacitor hybrid system explained by company's CTO

"We are a game-changer and a provocateur," Lamborghini's CTO, Maurizio Reggiani told Engadget. The automaker has a long history of making waves with traffic-stopping designs and more recently, innovative tech. At last week's Frankfurt Motor Show, the Italian company unveiled its Sian hybrid supercar. But it ditched the traditional battery pack in favor of a supercapacitor to power an electric motor, which is exactly what you would expect from the Italian company. Typically a hybrid uses a lithium-ion battery pack to store energy. Then when needed, it transfers an electrical current to a motor (or motors) to either help the gas-powered engine or take over propulsion entirely. It's a recipe that has successfully improved gas mileage and sold over six million examples of the Toyota Prius, not to mention countless other hybrids. "It's too easy to follow," Reggiani said. "If you want to move for the first time in electrification you must guarantee that the implementation will not destroy the DNA of a car and brand." With that in mind, the automaker went with a supercapacitor instead of a battery. According to Reggiani, the supercapacitor offers up three times the power of a battery pack from the same weight and packaging. Plus, it stores and discharges energy much quicker. The spent power can be fully regenerated very quickly during normal braking. Reggiani explained that this could be particularly useful while cornering. Going into a corner, the driver applies the brakes and replenishes any spent energy. Then, as the driver accelerates out of the corner, all the available power is there for acceleration. Then as the driver brakes for the next curve, the process starts all over again. Plus, the supercapacitor doesn't have to cool down like traditional battery, it's just ready to go at all times -- which is exactly what Lamborghini owners want. The output of the 48-volt motor installed into the gearbox is 34 horsepower which brings the total power output of the V12 Sian to 819 horsepower. While 34 horsepower doesn't seem like much, it means the vehicle can do zero to 62 miles per hour in under 2.8 seconds. That's Tesla Model S Performance and Porsche Taycan levels of fast. But there are other benefits. The electric motor reduces the torque hits of the gears shifting. You know those momentary losses -- then explosions of power -- you feel in the car as it speeds up, that's the vehicle going through its gears.

Lamborghini to price Urus similar to Huracan

If and when the Urus project is finally approved for production, it will take Lamborghini into not one but several new territories. For one, it will be the company's first SUV since the demise of the LM002 in 1993. It'll also be the company's first front-engined model since the demise of the Jalpa and Espada in the late '70s, and its first model to offer hybrid and turbocharged powertrains in, well... ever. Just don't expect it to be its cheapest model.
According to Motoring.com.au, in speaking with Lamborghini sales and marketing execs, the Urus "will be priced similarly to the Huracán," which is currently the Raging Bull marque's entry-level model. That doesn't mean, necessarily, that the Urus (pictured above in Beijing alongside the previous Gallardo) couldn't undercut the Huracán's price slightly - especially since it will likely offer more than one engine option - but don't expect it to come cheap.
The Huracán starts in the US for $237,250. If, as reported, the Urus commands a similar price, that would make it the most expensive SUV on the market. That is, at least, before other high-end rivals from the likes of Bentley and Maserati get into the game.

Lamborghini Huracan could become an 850-hp PHEV next year

So far, Lamborghini is celebrating 2022 with record sales and odes to the internal combustion engine thanks to a raft of special editions. The Italian automaker's plunge into electrification starts next year with the next-generation Huracan and its plug-in hybrid powertrain. Lamborghini's head of research and development said, "The engine will be bespoke for Lamborghini. On the final details we can’t yet communicate this, but I would say more than six and less than 12 cylinders for the combustion engine." The easy (well, easier...) option would be to tweak one of the Volkswagen Group's twin-turbo V8s to work with a pair or trio of electric motors. Auto Express says its sources suggest two bits of intel on that engine, the first being that it could be an in-house design "not sourced from VW Group," the second that combined output might exceed 850 horsepower. Such a theoretical coupe would be 169 horses more potent than the Huracan STO and easily satisfy Mohr's assertion that the new generation "from the performance point of view ... will again be a big step." Lamborghini is spending $1.8 billion on its path to an electric future. It's possible the firm could take part of that money to develop a V8 for itself, instantly setting itself apart from the other high-dollar brands in the VW Group. Naturally, we'd love to see that, or even a hybrid V10; what a monster that could be, although heavy, and engineers have been clear about waging a war against weight. The Wolfsburg parent is known to be a huge fan of scale, though, and a V8 or V10 that only serves two vehicles — the Aventador will continue with a V12 even as a plug-in hybrid — seems like a stretch to get approval. Parsing this also depends on how the automaker could define "in-house design." We've seen massively revised engines built around an existing block considered "all-new." The Huracan could debut as soon as next year, one year ahead of the automaker's commitment to electrifying the whole three-car lineup. Autocar says that looking ahead from there, we'll finally get eyes on the battery-electric Lamborghini in 2028. Last year, the predicted window was sometime between 2025 and 2027, and an interview with Lamborghini chief Stephan Winkelmann has clarified a few bits.
