Joining the lineup for the 2020 model year is the DBS Superleggera convertible variant, which is beginning to reach retailers. Like the coupe, power comes from a 5.2-liter twin-turbo V-12 that packs 715 hp and 664 pound-feet of torque. It's offered only with a ZF eight-speed transmission.

After the DB11 lineup was bulked up last year, the two-door, which is offered as a coupe, convertible or AMR performance variant, carries on for the foreseeable future.

The redesigned Vantage went on sale last year.

Deliveries of the Speedtail, McLaren's three-seat hypercar with a starting price around $2.3 million, are to begin in January.

Production of the road-legal Senna, which was limited to 500 units, has ended. Production of the track-only GTR variant is ongoing.

With the spider version launched, the next variant will likely be a high-performance version under the Longtail nomenclature.

The new model is the automaker's answer to other brands' ultraluxury and exotic supercars meant for the road and long distances.

Production of the 600LT coupe has wrapped up, while production of the 600LT Spider will continue through the spring of 2020.

A freshening of the four-door sedan is expected to arrive in late 2020. The Panamera 4S trim will receive a 2.9-liter, twin-turbo V-6 mild-hybrid powertrain, which debuts in the 2020 Audi S6 and S7 sedans this year. A Panamera redesign could arrive by early 2024.

The redesigned 2020 Porsche 911 receives upgrades in horsepower, a new interior layout inspired by 1970s models and added convenience features. The turbocharged flat-six engine on the 911 Carrera S and 911 Carrera 4S produces 443 hp, an increase of 23 hp from the outgoing model.

A new variant of the Cayman arrives in U.S. dealerships in the second quarter of 2020. Like the Spyder, the 718 Cayman GT4 is powered by a 4.0-liter naturally aspirated flat-six delivering 414 hp.

Porsche's best-selling U.S. model will go all-electric.

Porsche will launch a sportier coupe variant of its midsize crossover in the fall to compete with the Mercedes-Benz GLE Coupe and BMW X6.

Porsche's first battery-electric sports car is true to the brand's performance characteristics, with its top variant capable of 0 to 60 mph in 2.6 seconds and covering a quarter-mile in 10.8 seconds.

The Sian FKP 37, one of the highlights of the Frankfurt show, is a limited-run hybrid supercar.

Lamborghini's hot-selling SUV remains unchanged for the 2020 model year. Variants are likely in the near future, according to press reports. A plug-in hybrid with a V-8 could arrive around 2021. A high-performance variant is likely.

Deliveries of the Aventador SVJ and Aventador SVJ Roadster are underway, and the track-focused variants will continue unchanged into next year.

For the 2020 model year, all Huracans, both coupes and convertibles, are under the Evo moniker. The Huracan Evo is powered by a 5.2-liter V-10 engine with 640 hp and 443 pound-feet of torque. Inside is a new 8.4-inch touch screen infotainment system. U.S. deliveries are underway.

Given Lamborghini's longer life cycles, a replacement for the Huracan is not likely before 2024. When it arrives, it will be a plug-in hybrid.
