Amazon Prime customers in various US cities can now receive parcels direct to the boot of their GM or Volvo models.

Volvo Cars adds in-car delivery by Amazon Key

The service means drivers can track and receive in-car deliveries within an estimated 4-hour delivery window for supported vehicles parked in a publicly accessible area.

The service works using an encrypted authentication process. No special codes or keys are given to the driver. The driver will then place the package inside your vehicle and request to relock it. Drivers then get a final notification confirming the delivery is complete.

The Amazon Key In-Car Delivery service supports most 2015 model year or newer Chevrolet, Buick, GMC, Cadillac and Volvo vehicles with an active connected car service plan such as OnStar or Volvo On Call. Further partner announcements are expected in the future.

The service uses the Amazon Key app and is available on tens of millions of items sold on Amazon.com and works with same-day, two-day and standard shipping.

Volvo has previously launched similar services in Sweden and Switzerland but said the new collaboration represents a major scaling up of its connected car services.

“Simplifying the customer experience is central to Volvo’s digital vision. Receiving a package securely and reliably in your car, without you having to be there, is something we think many people will appreciate. This mix of car and commerce is starting the next wave of innovation, and we intend to be at the forefront,” said Atif Rafiq, chief digital officer at Volvo Cars.

Audi has also previously run an in-boot delivery trial with Amazon Prime and DHL, carried out in Munich.
