Jaguar straight 6 engine

As a parent of two young children, I watch a lot of movies at home. Most of the blockbuster movies I’ve watched this year are remakes. This month alone, I watched Ghostbusters, Star Trek Beyond, and Star Wars: The Force Awakens. All three are part of franchises that died a decade (or more) ago and have been reborn successfully in 2016.

In the same way, inline-six engines have returned to Mercedes-Benz after nearly a 20 year hiatus in North America.

Why are straight six engines making a comeback?

2017 Fiat 124 Spider

Sajeev,

I asked Bark for advice a few months ago and this question is somewhat related: I’m now planning to get a Miata or maybe the Fiat 124. I live at 5,000 feet above sea level and from what I’ve read, it sounds like the average naturally aspirated engine loses 3 percent of its power for every 1,000 ft increase in elevation, which translates to a 15 percent power loss at 5,000 ft. However, it appears that turbo engines do not suffer as much, as they lose about 1.5 percent power per 1,000 ft on average due to the less dense air. (i.e. more dense with forced induction – SM)

If that is the case, than I expect it would be better for me to get a turbo engine — provided I’m okay with the Fiat. (Read More…)

While in recent months TTAC has reported on the declining popularity of the four door, there are still a plethora of fast sedans in the marketplace.

In fact, the performance extracted from them was unfathomable even a generation ago. How did we end up at a 500-horsepower Audi, a 640-horsepower Cadillac and 707-horse Dodge? What were once numbers reserved for otherworldly exotics now are found in a pedestrian nameplate.

But this is no new trend, for while the current power war we’re experiencing has generated outlandish performance numbers for a mere average Joe, the recipe of sticking the most punch possible into a sedan for the masses goes back a long way.

It was impossible to escape the word “Turbo” in the 1980s.

There were Turbo Aviators and Turbo Hoover vacuums. Turbo was a character on American Gladiators. There was even Turbo chewing gum, which came with a cool mini car poster wrapper. Turbo was a helluva drug in the 1980s, and Chrysler took note.

BMW offered one turbocharged gasoline model. Porsche offered three. But Chrysler? Over a 10 year span, the Pentastar turbocharged its entire car lineup, bringing us some 20 turbocharged models powered by no less than six different variations of the 2.2- and 2.5-liter inline-fours.

It was 1998 and my friend Tom had just picked up a 1991 Eagle Talon TSI AWD.

“Ok, go ahead and floor it, but don’t rev it past 5,000 rpm,” Tom said.

I mashed the throttle and … nothing happened.

We were moving, but it was at the pace of a Toyota Corolla and nowhere near the rate of acceleration promised by the 2.0-liter turbo’s claimed 195 horsepower.

Disappointed, I left my foot on the throttle for a few seconds. Suddenly, I heard the whistle of the spooling turbo and a sudden shove of boost kicked in.

Four-cylinder turbo engines from the ‘90s were all similar to this. While they generated relatively big power at the top end, they also suffered from massive turbo lag and had fuel economy similar to a much larger V8.

Nissan’s new Variable Compression Turbo engine promises big power, minimal turbo lag, and decent fuel economy using some new trickery.

Is this the holy grail of turbocharged motors?

Who built the first 250-horsepower Quattro? The first turbocharged German wagon? The first long-wheelbase Audi with all-wheel drive? The first all-wheel-drive convertible? The first off-road-inspired Audi? The first aluminum space-frame car? The first mid-engine car with Volkswagen’s Audi Group underpinnings?

Not Audi.

They all came from the mind of one incredible engineer named Walter Treser.

It’s not that Treser was without connection to the company, though, as he was intimately involved with developing the legendary Quattro and other models, then later headed up Audi’s rally program. Sure, Ferdinand Piëch gets all the credit for being the visionary that made all-wheel drive possible, but Treser is the engineer that actually turned that vision into reality.

But he didn’t rest on his laurels for long.

Hi Sajeev,

I have a confession to make. I may have lied on my last TrueDelta survey. I reported ‘No Repairs,’ but, while technically true, I have been struggling with a problem for a few months now. My 2011 Ford Taurus SHO has been my long distance cruiser for 99,000 miles now, often times pulling an eight-foot trailer full of bikes and gear to track days all over the Southeast. I installed an Airraid cold air intake, Corsa Cat-Back exhaust, and Stage 3 tune from Livernois Motorsports at 17,000 miles, and the car has run fantastic until about 4,000 miles ago.

Porsche 924 Turbo (931)

There are few better ways to get instant recognition as a connoisseur of cars than to drive a classic. People will applaud your discerning taste, your unique choice in an age of appliance automobiles. Good for you!

You’ve decided to get something German because you like your 1970s classic to run. And you’d like a sports car, which pretty much makes Porsche your default choice. Few models now generate the collective automotive “OOoooo!” of the air-cooled 911. It’s so cool, it’s backwards!

But then you find out what classic 911s cost. If you’ve been living under a rock recently, prices for classic and rare 911s are through the roof. One of the last great air-cooled models just sold at RM Sotheby’s London Auction for £1,848,000. I’ll save you some quick math: that’s $2,460,242 USD at time of writing.

As you wipe the coffee from your screen, allow me to suggest it doesn’t have to be this way. You, too, can have an obscure, classic Porsche for only around 1/1000th the price of an air-cooled 911.

Recognize this Kia?

TTAC’s Matthew Guy drove and reviewed this particular 2017 Sportage SX Turbo in early July. Readers need not an ability to read between the lines to locate Guy’s disappointment in the turbocharged 2.0 liter’s responsiveness, or the nearly complete and total lack thereof.

“Kia’s intent is to offer V6 power with four-banger economy. Unfortunately, I found little of either in this Coke-bottle-sized engine,” he wrote at the time.

The Sportage SX, rated at 237 horsepower and 260 lbs-ft of torque, shuffles its power through all four wheels in a 3,997-pound package. In a 2016 Kia Sorento weighing 4,303 pounds, I said the same powerplant’s mid-range “is as punchy as the Sorento’s available 3.3-liter V6,” and “passing power is plentiful as you ride a 260-lb-ft wave across a plateau of torque.”

Yet in the smaller and lighter Sportage, Matthew says, “Outside Sport Mode, it didn’t even feel like 137 hp, let alone 100 more.” In TTAC’s hyperactive Slack chat at the end of July, he continued, “It drove like cold molasses going backward uphill.”

But Guy was the first auto writer to get seat time in this specific 2017 Kia Sportage SX Turbo. Unbeknownst to him, and to the Kia Sportage’s instrument cluster, the Kia was wounded before getting to the battlefield. (Read More…)

After scoring a stellar deal on our ’15 Ford Fiesta 1.0 EcoBoost, thanks to the advice of those who know more about the car buying process than I do, my girlfriend and I have put just over 3,000 miles on our diminutive hatchback.

In those 3,000 miles, the Fiesta has patiently allowed Jenn to hone her manual-transmission skills, been to the dealer once (more on that in a bit), carted us and our furry dependents around the province, and not once been close to an autocross course — though not due to my lack of trying.
