Tier 1 suppliers call GM the worst OEM to work with

Among automakers with a big US presence, General Motors is the worst to work for, according to a new survey from Tier 1 automotive suppliers, conducted by Planning Perspectives, Inc.
The Detroit-based manufacturer, which has been under fire following the ignition switch recall and its accompanying scandal, finished behind six other automakers with big US manufacturing operations. Suppliers had issues with trust and communications, as well as intellectual property protection. GM was also the least likely to allow suppliers to raise their prices in the face of unexpected increases in material cost, all of which contributed to 55 percent of suppliers saying their relationship with GM was "poor to very poor."
GM's cross-town competitors didn't fare much better. Chrysler finished in fifth place, ahead of GM and behind Dearborn-based Ford, which was passed for third place this year by Nissan. Toyota took the top marks, while Honda captured second place.

The 2022 Subaru BRZ and Toyota GR 86 aftermarket upgrader's guide

When you own an enthusiast car, there are few events more nerve-wracking than the introduction of its successor. Should you upgrade? Is it worthwhile? What will it cost you to part out your mods and trade up? Well, there's good news for owners of the outgoing Scion FR-S, Toyota 86 and Subaru BRZ who are considering an upgrade: You might not have to start with a clean slate.  If you’re an owner (or even a casual fan) of the Subaru BRZ/Toyota 86 family of sports coupes, youÂ’re probably already aware that the 2022 models are more like aggressive overhauls than true, ground-up redesigns. Neither company really wants to put a spotlight on the fact that their coupes are a little less "all-new" and a little more "back and better than ever," but in our opinion, this is something Subaru and Toyota should embrace.  Why? In a word: continuity. Look no further than the NA (1989-1997) and NB (1999-2005) Mazda Miata. While they are regarded as distinct generations (the NA defined by its pop-up headlights and simpler lines; the NB by its fixed lamps and swoopier styling) and were offered with different equipment packages, the fundamental underlying chassis remained relatively unchanged. This meant that, in many cases at least, buyers could trade up to a new model but bring along some of their factory and aftermarket accessories because theyÂ’d still fit. The BRZ and GR 86 are meant to be fairly bare-bones vehicles, the idea being that they appeal to those who want limited frills at a low cost and those who prefer to view cars as canvases rather than finished masterpieces. A long-running platform makes an excellent candidate for the latter type of car buyer. So, what does that mean for the 2022 BRZ and GR 86? Well, let's break it down by whatÂ’s truly new, whatÂ’s kind-of-new, and whatÂ’s essentially carry-over, with some guidance from Subaru and Toyota engineers.  2022 Subaru BRZ blue action profile View 22 Photos Spankin' new LetÂ’s start with the obvious: the styling. Even if you can find older aftermarket appearance kits that will fit the new BRZ and GR 86 on paper, they probably wonÂ’t bolt up nicely to the new cars due to their sleek new exterior designs. Wings and spoilers might still bolt up, but donÂ’t count on it, and theyÂ’ll probably look disjointed at best anyway.

Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.
