What We Know So Far


Hidden underneath the 2021 Lamborghini Sián’s dramatic hexagonal bodywork and bevy of air intakes is a hybridized V-12 powertrain that harnesses 807 horsepower. That’s right, this hypercar is a hybrid. Basically a heavily modified version of the aging Aventador, this exotic comes in coupe and roadster form, and Lambo has capped its production at a scant 82 copies. (Spoiler alert: They’re all sold out.) We suspect each carries a seven-figure price tag, but that money buys a truly special-looking, high-performance machine even before customization. Not only is the 2021 Sián an electrifying Lamborghini, but it also moves like a metaphorical bolt of lightning, too.

What’s New for 2021?

The 2021 Sián is a new limited-production Lamborghini that looks to bridge the gap between the outgoing Aventador and its upcoming replacement.

Pricing and Which One to Buy

    Lamborghini hasn’t disclosed how much the 2021 Sián coupe or roadster costs, but we’re guessing it’s above a million dollars before options. Buyers can customize these pricey rides with various trim options and paint colors, and they can choose to have their initials incorporated into the 3-D-printed air vents. Lambo will build only 63 coupes and 19 roadsters, all of which are already sold out.

    Engine, Transmission, and Performance

    Powered by an electrically assisted 6.5-liter V-12 mounted in the middle of the car, the all-wheel-drive 2021 Sián produces a combined 807 horsepower. That makes it the most powerful production Lamborghini ever. On its own, the naturally aspirated V-12 supplies a hefty 774 horses. Supplementing the engine is a 48-volt electric motor that adds 34 horses and is integrated into the car’s seven-speed automated manual transmission. It’s one of the most sophisticated hybrids on the planet, utilizing a supercapacitor stored in the bulkhead instead of a more traditional battery pack. Not only does this setup deliver superquick regenerative braking and acceleration, but it also reduces the harshness between shifts. Plus, the Sián can be maneuvered at low speeds on electricity alone, which should provide a nice reprieve from the V-12’s sputtering nature in parking scenarios. Lamborghini claims the coupe and roadster will blast to 62 mph in 2.8 and 2.9 seconds, respectively, and top out at 218 mph.

    Fuel Economy and Real-World MPG

    Neither the EPA nor Lamborghini have released fuel-economy estimates for the 2021 Sián. However, we anticipate the hybrid powertrain will make the Sián more efficient than the environmentally offensive Aventador. Per the EPA, the latter sees up to 9 mpg in the city and 15 mpg on the highway. In the unlikely chance that we get to test the Sián on our 75-mph highway fuel-economy route, which is part of our extensive testing regimen, we’ll let you know how it measures up in the real world.

    Interior, Comfort, and Cargo

    Inside, the Sián lives up to its exotic nature, as every surface is covered in high-end materials. Of course, Lamborghini allows customers to personalize the interior to their taste. The driver faces a fully digital gauge cluster and a buttonless steering wheel with enormous paddle shifters. The center console has physical controls for the climate system, the selectable drive modes, and other auxiliary functions. While the Sián does have a glovebox, it lacks cupholders and small-item storage.

    Infotainment and Connectivity

    The Sián boasts a vertically oriented infotainment touchscreen, and we suspect it has Apple CarPlay capability and Amazon Alexa integration. A more powerful audio system than the standard stereo is likely available for extra cost.

    Safety and Driver-Assistance Features

    The Sián does without the driver-assistance technology that less extraordinary cars offer. And due to its exotic nature and limited production, this Lambo won’t be crash-tested by either the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS).

    Warranty and Maintenance Coverage

    Compared with most mainstream automakers, Lamborghini doesn’t provide stellar warranty coverage. But its basic protection policy is on par with that of its crosstown rival, Ferrari, and can be enhanced by optional maintenance packages.

    • Limited warranty covers three years or unlimited miles
    • Powertrain warranty covers three years or unlimited miles
    • No complimentary scheduled maintenance
