EV startup Rivian has kept quiet since the company purchased a disused Mitsubishi factory in Illinois a couple of years ago. The silence will be broken later this month, however, as the company has announced it will be revealing the R1T electric pickup at the LA Auto Show as a rival to the upcoming Tesla pickup.

Ahead of its LA debut, Rivian has released a teaser video giving us a brief glimpse at the R1T's distinctive design. At the front, the unique front fascia features a slender light bar connecting two vertically stacked LED headlights, and there's also a full-width light bar at the rear. Additional details are difficult to make out, but previous reports have suggested it will be around the same size as the Honda Ridgeline. From the teaser, it definitely bears a strong resemblance to the Ridgeline at the back.

Rivian hasn't shared any technical details, but the entry-level R1T is expected to have an 80 kWh battery pack, a range of around 200 miles, and a 0-62 mph time of less than five seconds. It will reportedly have a base price of $50,000.

There could also be a high-performance model costing around $90,000 with a larger battery pack that enables the truck to travel 450 miles on a single charge. The range-topping R1T is slated to have 800 hp, which will allow it to reach 62 mph from a standstill in just 2.8 seconds. Rivian will reveal the R1T at 7.30pm PST on November 26. The next day, the startup will also reveal a three-row electric SUV called the R1S after 11.50 am PST.

Both models will go on sale in 2020, which is when Tesla pickup deliveries are also slated to begin, and will offer "impressive on- and off-road performance figures and class-leading specifications including range, power, torque and off-road articulation."

Rivian added that both models will "demonstrate that electric vehicle technology is now able to deliver durable, long-range on- and off-road capability to consumers."
