Why Hydraulic and Electric Power Steering Feel Different Chris Perkins © McLaren As ever, there s a simple scientific explanation.
The debate between the merits of hydraulic and electric power steering is set to continue for years to come. Using electric assist in a sports car isn t a bad thing if it s tuned well, but there s no doubt that hydraulic assist feels different. Naturally, there s a very simple scientific explanation for this.
Engineering Explained s Jason Fenske discussed the difference with a McLaren engineer. McLaren is fairly unusual among automakers for its commitment to hydraulic power steering, and that s because it finds that modern electric-assist systems, a lot of the vibrations that a road transmits to the tires and get filtered out on their way up to the steering wheel.

Ford has announced more production cuts, including to the long-awaited Bronco, due to chip shortages. The company says it will extend downtime starting May 17 at its Michigan Assembly plant, but insists the first Broncos will still reach dealerships and eager buyers this summer.
Manthey Racing has worked its magic on the 991.2 Porsche 911 GT3 RS and recently took the car to the Nurburgring to see what it was capable of. Mods include KW adjustable coilovers and a custom rear wing for extra downforce on the ’Ring’s fastest, scariest turns (which, looking at this vid, is all of them).
Mercedes has expanded its recently announced EQA lineup to include the EQA 300 4MATIC and EQA 350 4MATIC. Offering buyers a step-up from the single-motor EQA 250, the new models are equipped with dual-motor all-wheel drive systems, develop 225 and 288 hp, and offer up to 268 miles of WLTP driving range.
Engineering Explained: No, Model S Plaid Can t Hit 60 MPH In Under 2 Seconds
May 05, 2021 at 10:22pm ET ++ And he s got a whiteboard full of figures to prove it!
The popular YouTube channel Engineering Explained has a problem with Tesla s claim that the Model S Plaid and Plaid Plus can accelerate from 0 to 60 miles per hour in under 2 seconds.
And that means Tesla has a problem because the host of the channel, Jason Fenske, doesn t make claims he cannot back up with science, facts, a whiteboard and a bunch of multi-colored dry erase markers.
The issue at the heart of the problem is the fact that Tesla uses rollout to achieve the claimed sub-2-second 0 to 60 times for the New Model S Plaid and Plaid+. In other words, it s not 0 to 60 mph, it s more like 6 to 60 mph since the Plaid and Plaid Plus will likely have accelerated to 6 mph by the time they have traveled the one-foot rollout and Tesla s stopwatch starts.
Despite the occasional bouts of controversy, there’s no denying that Tesla has created some of the most impressive vehicles of this era. So impressive in fact, that they continue to be an industry benchmark for legacy carmakers looking to play catch-up in the EV sphere.
And if there’s one key takeaway that anyone who’s been in a Tesla at full pelt will attest to, it’s the acceleration. We’ve seen their four-door sedans and SUVs destroy lightweight, carbon fiber draped supercars with an unfathomable acceleration. Now, they’ve taken that one step further.
Tesla recently introduced the updated Model S that comes with some subtle exterior upgrades, bold changes to the interior, a redesigned battery pack for extended range and two tri-motor versions, the Plaid and Plaid+, with a combined output of 1,020 HP and 1,100+ HP respectively.
