Porsche is making its 911 faster and adding more technology to keep its most lucrative model relevant as the industry shifts toward full-electric sports cars.
The latest 911, which debuts this week at the Los Angeles auto show, gets a new range of more powerful flat-six turbocharged engines available with a newly-developed eight-speed PDK double clutch transmission.
The engines' efficiency has been increased by an improved injection process, and a new layout for the turbochargers and charge air cooling system, Porsche said in a news release.
The 444-hp base Carrera S rear-wheel-drive model has 30-hp more than the current model. It accelerates from 0 to 100 kph (62 mph) in 3.7 seconds. Top speed is 308 kph (191 mph). The 911 Carrera 4S with all-wheel drive needs 3.6 seconds to do the sprint. Both cars are 0.4 seconds faster than the previous models, Porsche said.
Driver assistance systems include a "Wet" mode to make driving on damp roads safer. Customers can also order the car for the first time with a thermal imaging camera for better night vision.
The 911 has permanent connectivity that now also uses swarm intelligence, Porsche said.
