#Turbo

General Motors wants better performance from its boosted engines, so it headed to the patent office with a design for a new two-stage turbocharger — one that eliminates the drawbacks of the existing setup.

According to a document published by GM Inside News, the General filed the patent on May 19. The design (mated to a four-cylinder engine) isolates the low-pressure and high-pressure turbines, calling on one or the other (but not both) at different engine speeds and loads.

The complaint most often tossed at Formula 1 is that despite being the (alleged) pinnacle of motorsports, its relevancy to road cars has disappeared.

That same feeling is what brought us to the current formula of tiny 1.6-liter turbocharged six-cylinder engines, all coupled to a complex hybrid system. Since that move, the racing series has focused more on engine development that in almost any era before, and with that comes a breakthrough in the way we look at thermal efficiency.

Two weeks ago, we told you of a potent four-cylinder engine under development by Fiat Chrysler Automobiles. Now there’s physical proof of the so-called “Hurricane” mill.

Spy photos obtained by TTAC show a cloaked Jeep Wrangler test mule with the hood up and a pile of evidence underneath. The positioning of the oil fill cap points to an inline engine, and air intake ducting routed over the cam cover points to a turbocharger — in this case, a high-mounted one.

Now, will the Hurricane make the nearly 300 horsepower as has been claimed? That’s a wait-and-see thing.

The UNIversal-MOtor-Gerät, better known as the Unimog, is a portal-axle-equipped toy for the super-wealthy — or that’s what most people think, thanks to it often pictured as a luxury camper van in the depths of the wild. But all over the world, Unimogs spend their lives doing the kind of work they were designed to do in construction, railroad, utilities, fire departments, agriculture, and non-combat military. Overland expeditions, ironically, were the one function for which they were not originally conceived.The truth is that anyone can buy a used Unimog for a reasonable amount of money. In fact, my friend and 24 Hours of Lemons teammate Mike owns two. That’s right; my teammate owns not one, but two Unimogs! That blew my mind, because, seriously, how often do you even see a Unimog anywhere, never mind know a man who owns two?

The Ford Edge has always grabbed my attention due to its styling.

From a distance, the look — especially that of the second-generation Edge — is certainly pleasing to the eye. The front grille, fog light assembly, stylish wheels and a nice silhouette give the midsize crossover an Edge — pardon the pun. And the 2016 model can be configured in a number of ways to suit consumers’ needs, with a choice of powertrains and a nice choice of optional equipment.

But, as they say, the devil is in the details, and that’s where the Edge starts to lose its sharpness. The main issue is one we’ve seen here before: quality of the fit of the exterior panels of the Edge. However, I have another major gripe about the Blue Oval’s lifestyle-mobile, and it sits under its misaligned hood.

The Lexus RX isn’t a sales success; it’s a sales phenomenon. It’s a magical cash generating unicorn that can seemingly do no wrong. The RX outsells every other luxury vehicle in America. Despite sales being down 6.5 percent in 2015, the RX crossover nearly outsold the entire Lincoln brand. When the numbers were tallied, Lincoln brand as a whole beat the single Lexus model by just 617 units.

Why do I bring up the Lexus RX so early in a review ostensibly about a Lincoln crossover? Two reasons. We might as well talk about the elephant in the room and I genuinely don’t understand why the RX outsells the MKX by nearly 5:1. As I discovered during a week with the latest incarnation of Lincoln’s MKX, the Lincoln is quite simply a better Lexus than the RX.

The K-platform-based Dodge Daytona was built for the 1984 through 1993 model years and sold pretty well; we’ve seen a few of them in this series. The Daytona’s Chrysler-badged sibling, the Laser (not to be confused — though many do — with the Mitsubishi Eclipse-based Plymouth Laser), was sold only for the 1984-1986 model years and is a bit harder to find.

When the previous generation of Astra made it to American shores — dressed in leather, wood and Buick Verano badges — it wasn’t a foreign invasion. Instead, the Astra-cum-Verano was a good soldier coming home; the Astra J always felt like a Buick.

The brand-new Astra, now wearing the K designator, is lighter, more agile and stuffed with lots of new-fangled tech. Europeans love it, as shown by its European Car of the Year award. But will Americans love the next Verano, which is bound to be based on this European compact?

I wonder how many of the Best and Brightest have been watching, waiting for this column to descend once again upon a subject automobile that has had a truly mystical device bestowed upon it by its creator. I’m talking about the equipment that blew the expression right off your neighbor’s face when showing off your new purchase in the driveway. A true novelty lost to time. Something that probably should be capitalized on currently by automakers in an updated form in this age of “let’s fill this humorless pod full of unusable gadgetry so it doesn’t look like a rolling flip-phone.”

I’m talking, of course, about a little thing called voice warning.

You see kids, something magical happens when that speaker chimes in to apprise you of things you probably already knew about. And while we’re on the subject of cars so equipped, why not focus on something with … soul?

After the near-miraculous success of the K platform dug Chrysler out of the pit of its near-bankruptcy and controversial government bailout (no, not that bailout, the earlier one), Lee Iacocca led the company to produce a bewildering number of vehicles based on the K. Chrysler had some sporty machinery based on the Simca-derived Omnirizon (not to mention some hot rebadged Mitsubishis), but the Dodge Daytona and its Chrysler Laser sibling were the bread-and-butter factory hot rods of the 1980s and a bit beyond.

Here’s an ’85 I spotted at a now-defunct Los Angeles-area yard a while back.

Sajeev:

I have a question that I don’t believe you have answered before in your talking about design features, and that is the weird obsession car makers have with exhaust outlets.

Mitsubishi has a plan to gain market share in the U.S. that’s right out of the ’80s.

Dealers were told during last weekend’s National Automobile Dealers Association conference that Mitsubishi will introduce turbocharged engines to model line, according to Automotive News.

The forced-induction renaissance will begin with a 1.5-liter mill powering the automaker’s planned midsize crossover, expected in 2018, which will slot between an enlarged Outlander and the Outlander Sport.

Hi Sajeev,

I’ve toyed with the idea of turbocharging a 2.sl0w just for giggles and TORQUE, but the quest has to make some sense economically, or else the finance minister will not approve. Then it hit me: just how LOW in price have those older dirty diesels gone, anyway? You know, the ones with that lovely 236 pounds-feet of torque.

In other words, can I just get the torque without the spending abyss and busting my knuckles? Small data-set wise, four-cylinder manual Jettas with 64,000 miles average a diesel premium of only $675. At that consideration point, say 2010-ish Jetta, there is no economy for the project and I could jump right into the lovely torque.

So my question to you, on behalf of Torque Lovers Everywhere: is it time to pounce on diesel?

The BMW 3 Series has been the benchmark to which all manner of vehicles are measured. The comparisons go beyond the likes of the Audi A4, Mercedes-Benz C-Class and Volvo S60, and include BMW M3 vs Chevy Camaro and BMW 328d vs Toyota Prius. It seems that every car company in America makes at least one “3-Series fighter.” But there’s a problem with your largest volume product being put on this kind of pedestal: die-hard fans hate change.

Enthusiasts claim that BMW ruined the 3 Series when they redesigned it in 2012. The “F30” sedan got bigger, fatter, softer, and more gadget-filled than ever before. BMW fanbois cried in their gemüsesuppe, Road & Track called it an “also ran” and … BMW laughed all the way to the bank.

For 2016 the 3-Series gets a facelift, new engines and a redesigned suspension. What isn’t changed, however, is BMW’s new direction. And that’s a good thing in my book.

In case you didn’t know it, Kia’s on a roll. Sales have more than doubled since 2009, propelling Kia from a Mazda-sized player in the American market to one that outsold established brands like Subaru, GMC, Chrysler and Volkswagen.

Kia’s transformation may seem like a night-and-day makeover, but closer inspection reveals that it’s really the result of consistent incremental improvements to its products, frequent designs and refreshes, and astute pricing.

You can think of the Sportage as the final piece of Kia’s evolving puzzle. Sales may be on a roll for the Korean automaker, but the Sportage has never sold in large numbers. It finished 14th in a segment of 17 models last year. (The Sportage beat the Volkswagen Tiguan, Mitsubishi Outlander, and Chevrolet Captiva Sport). It could be that the Kia Sorento did a better job of nipping at the heels of mid-trim Toyota RAV4 and Honda CR-V models. For 2017, Kia gives us a new Sportage targeted more at Mazda and Ford than Toyota.
