Amazon has confirmed it now plans to launch the first two test satellites for the company's Kuiper broadband network on a United Launch Alliance Atlas V rocket as soon as next month, shifting the payloads off of the inaugural flight of ULA's new Vulcan rocket.

The shift has been rumored for several weeks after ULA delayed the first flight of its Vulcan rocket from the summer until the fourth quarter of the year. The delay will allow time for ULA to beef up the structure of the Vulcan upper stage's liquid hydrogen tank, which sprung a leak that resulted in a destructive fireball on a test stand in March.

The first Vulcan rocket was slated to launch the first two prototype satellites for Amazon's Kuiper constellation, a network of more than 3,200 broadband satellites that the retail and tech giant plans to deploy over the next few years. The Kuiper network is similar to SpaceX's Starlink "mega-constellation," which already has more than 4,000 satellites in orbit.

A few weeks ago, we reviewed Lexus' new battery-electric vehicle and came away underwhelmed. Today, it's the turn of its Toyota cousin, the closely related (and unfortunately named) bZ4x. The electric Toyota had a troubled launch last year when the cars had to be recalled due to wheels that might fall off. That's all solved now thanks to new bolts, washers, and wheels, so we finally spent a week with the bZ4x. Given this EV's initial reception, I was prepared to be disappointed, but by the end of the week, I was pleasantly surprised. The Toyota isn't particularly flashy, but it is more efficient than I was expecting.

Let's start with the name, because it's a little weird. But there's a reason behind the alphanumeric jumble. Toyota's plan to reach carbon neutrality is called Beyond Zero, so the EVs it's building to get there adopt the bZ moniker, thus bZ4x. You may want to call it Bizzyforks as at least one friend of mine does—no one will stop you if you do.

Like the Lexus and the Subaru Solterra, the bZ4x uses Toyota's e-TNGA platform; I mistakenly wrote in that Lexus review that it was an existing platform—it's actually not. It's roughly the same size as the Lexus, too—the wheelbase is an identical 112.2 inches (2,850 mm), but it's a bit shorter (184.6 inches/4,689 mm), a bit narrower (73.2 inches/1,859 mm) and slightly taller (65 inches/1,651 mm).
