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 Accademia at Mazda Raceway Laguna Seca

I found it to be a rare, genuinely rewarding educational experience.
Lamborghini is putting more effort into its North American motorsports efforts and promotion, so we recently attended its first-ever Intensivo driving school at Mazda Raceway Laguna Seca, spending a day behind the wheel of both its Huracán and Aventador supercars. Offered under the Squadra Corse banner, Experienza is designed to provide a taste of Lamborghini's cars on a circuit, Intensivo is designed to maximize track-time learning, and Accademia and Advancada - only in Europe for now - are focused on the driver and driver technique. Beyond those, Squadra Corse can also provide Super Trofeo instruction to get you fit for the Blancpain one-make series and GT3 racing, too.

Lamborghini NA V12 swan song a track-only 830-hp Aventador SVR?

According to a poster on a McLaren Life forum and picked up by The Supercar Blog, Lamborghini is preparing a small-batch, track-only model to begin deliveries around 2021. At the end of last month, user Champagne612 wrote that he (or she) was "Going to spec next week and test drive the SVR V12 track version of AV." In the words of Champagne612, this Aventador SVR is the last hurrah for Lamborghini's naturally aspirated 6.5-liter V12, a flourish before hybridization becomes necessary on the brand's iconic powerplant. Supposedly, only 40 SVRs will be made, each one producing 830 atmospheric horsepower. That would give the SVR 60 more horses than the road-legal SVJ. Lamborghini's only made two other SVR models. In 1968, there was the one-of-one Miura Jota SVR, a customer-request Lamborghini brewed with a mix of outsourced parts. More relevant to this latest car, in 1996 Lamborghini built 31 examples of the Diablo SV-R — based on the Diablo SV — to form a one-make race series. It's not clear if the coming SVR will be just a customer track-day car, a la the new Porsche 911 GT2 RS-based 935, or if Lamborghini has larger plans, a la the Ferrari FXX-K program. The Sant' Agata brand has leaned even more into the customer racing vibe of late, with a Urus one-make series planned, and the customer-request, road-legal Aventador-based SC18 Alston unveiled last year (pictured). Based on that, there's chatter that an Aventador SVR could be a feint at the so-called hypercar class opening next year in the World Endurance Championship. The connection seems more than tenuous, but it's not impossible. Lamborghini CEO Stefano Domenicali said at the Goodwood Festival of Speed that the carmaker was perusing the hypercar regulations taking effect in 2020 until about 2025, and told Autocar that the SC18 Alston "shows that we have internal capabilities for such a [Le Mans] project." Those rules require a minimum weight of 1,100 kilograms, maximum combined output of 750 hp — an optional hybrid system can contribute no more than 270 hp — and a minimum of 20 production versions built over two years. Save for the fact that committed entries from Aston Martin and Toyota are much more slippery than any Lamborghini, the rules on paper put an Aventador-based model firmly in the mix, and unresolved regulations limiting downforce and mandating a minimum drag figure could inch an Italian competitor closer to the mark.
