Engine braking and rocket thrust fill Engineering Explained's upload break
Jason Fenske's back catalog brought roughly 3.5 million views during a week without a new release.
Why this story? The channel's weekly summary: what went up this week, what is drawing views now, and where the channel stands among similar channels.
I Fact-Checked Every Stunt in the Tesla Roadster Reveal
Lift off the throttle in a gasoline car and the engine becomes part of the braking system. Engineering Explained's "Why Downshifting To Slow Down Is Actually Genius – Engine Braking!" follows that resistance back to the pistons, which must pull air past a nearly closed throttle valve. A lower gear makes the engine repeat that work more often, helping slow the wheels.
That summer explainer remains among the channel's most active videos, though Jason Fenske's Tesla Roadster fact-check is drawing a much larger daily audience. With no new upload this week, the contrast is particularly enjoyable: everyday driving technique alongside a car supposedly capable of flying over other cars.
In "I Fact-Checked Every Stunt in the Tesla Roadster Reveal," Fenske finds that suction-assisted upside-down driving and a short nitrogen-thruster flight are mathematically plausible. He is less persuaded by the claimed acceleration of the fanless base car. The distinction matters: a stunt working on paper isn't the same as a production car arriving as promised.
The channel added about 10,000 subscribers over the week, although daily views are now a little below their usual level. Among nearby motoring channels, Forrest's Auto Reviews had a particularly substantial viewing week; DailyDrivenExotics and Jay Leno's Garage are both drawing above their usual daily audiences.
Fenske's own electric-car shopping story also remains active. His highlighter-orange Mustang Mach-E GT offers a more attainable sort of spectacle than the Roadster: a used-car purchase chosen partly because someone else had already absorbed the steep depreciation.

What chiefly restricts incoming air during the gasoline-engine braking explanation?
Lifting off the accelerator nearly closes the throttle valve, leaving the pistons pulling against restricted airflow.
