The first subscription tier starts at $2,000 a month and allows users to summon a 718 Boxster, Cayman S, Macan S or Cayenne on demand. For $3,000 a month, drivers get access to 22 different Porsche models. Registration, insurance and maintenance costs are covered, though subscribers still have to pick up the tab for fuel. They can swap for as many different models as desired during the month.
 
 Porsche is looking for a way to reach younger consumers whose shopping and transportation habits have been shaped by Silicon Valley giants like Uber Technologies Inc. and Airbnb Inc. It’s following in the footsteps of General Motors Co.’s Cadillac, which launched its Book subscription service in January, and Care by Volvo, which combines lease, insurance and maintenance into one monthly payment.
