About the 2021 GMC Sierra AT4

Car with driver: the 2021 GMC Sierra AT4. Here is the car in plain words, and how renting one from CarmaCars works. Chauffeur bookings are by the hour, two hours minimum; send a request and we reply with the vehicle we can offer and the price.

The Sierra and Knobs

Next door to Knobs are Johnson Crossroads, Elmhurst and Union.

Specs, explained

The 3.0L 6-cylinder turbo is what moves it, with four-wheel drive. It runs on diesel, sold at most highway stations. Four-wheel drive helps on rough ground and deep snow; on dry roads it behaves like any other vehicle.

The combined figure, 9.9 L/100 km, means roughly 30 litres for 300 km. For 1,000 km, budget about $153.50 at our price setting.

Space, size and seats

It is built for loads that would never fit in a trunk.

Good uses for the Sierra

It suits a family trip where everyone and everything fits in one car. It suits a stretch between cars, by the week or the month.

Renting it

Meanwhile, 6 similar cars are listed below. Ask for this exact car in your request, and we tell you what we can offer. We have none on the site right now. Send a request for this exact car and we look for one for your dates. Your offer shows any delivery fee before you pay.

What we check

Ontario G2 or G licences are accepted, for drivers 18 and older. No maximum age, and a daily fee only for drivers under 26. Your original licence, not a photo, comes with you to the handover.

If you have no auto policy and no card benefit, the CarmaCars Protection Plan is the third option, priced in your offer. The deposit comes about 1 hour before you get the car, not at booking. We check every driver; it takes a few minutes and protects everyone.

From your dates to the handover

Send the request with your dates first; no money changes hands at that stage. An offer follows, with the car we confirm and the full price for your dates. Say yes to the offer and pay; that is when the booking is made.

The rates you see on a car's page are the rates in your offer. From 7 days, the weekly rate applies; up to 365 days, a trip never costs more than the monthly rate. Book ahead if you can; 2 hours is the shortest notice we take.
