Sajeev,
Brett here. Got a weird one, or maybe it is not that weird since it involves a Chrysler product and electrical gremlins. My father drives a 2006 Jeep Commander, 5.7-liter HEMI, basically loaded. Overall, he likes the Jeep. It has about 104k miles on it. Anyways, it is his forth Jeep and he is having some weird electrical problems.

Imagine that, a Chrysler product with electrical problems… (Read More…)

2015 GMC Sierra Crew Cab SLT 4×4
6.2-liter OHV V-8, direct injection, cylinder deactivation, CVVT (420 horsepower @ 5,600 rpm; 460 lbs-ft @ 4,100 rpm)

Hydra-Matic 8L90 8-speed automatic

15 city/21 highway/17 combined (EPA Rating, MPG)

16.5 mpg, mostly city driving while yelling “AMERICA!” at full trot. (Observed, MPG)

Tested Options: 6.2L Ecotec3 V-8, navigation, polished exhaust tips, sunroof, spray-in bedliner.

As Tested (U.S.):
$52,300 w/ $1,195 destination charge (sheet)
As Tested (Canada):
$59,615 w/ $1,795 destination charge and A/C tax (sheet)

A farm, lots of mud thanks to rain from the previous day, and a dose of sunshine to dry out the ground just enough so my feet wouldn’t lose their boots in the slop. This is the perfect location — along with the perfect conditions — to test one of the latest from the pickup crop, the 2015 GMC Sierra.

Or is it?

Under the hood of the SLT-trimmed Sierra sits a V-8 less suited to farm duty and better equipped for automotive trolling.

Before we get into the meat and potatoes of the Sierra, I have a small announcement to make. TTAC now has an off-road area for testing trucks and SUVs. Sort of. It probably won’t be fully available for us for a little while, but shenanigans will be had before the end of the summer. Here’s hoping the automakers send us some metal so we can put it to the test at this newfound playland.

As for this Sierra, well, it isn’t a farm truck. Hell, it’s barely a work truck. The Sierra is available in four different trim levels — base, SLE, SLT and the top-trim Denali. Our SLT-trimmed tester arrived with its bench seat still intact, which is great for mid-summer-romance canoodling and one of the reasons girls dig guys with trucks, maybe.

Interior configuration aside, the real news for this Sierra is under the hood. The 6.2-liter Ecotec3 V-8, with its 420 horsepower and 460 pounds-feet of torque, is a nod to old-school solutions to making power and a pragmatic approach to efficiency. The pushrod V-8 might sound antiquated next to the new turbo and diesel units from Ford and Dodge, but that doesn’t make it any less valid.

2015 Lexus RC F Exterior

The last Lexus coupé-only model to grace luxury Japanese dealer lots was the 1991-2000 Lexus SC 300/SC 400. Since then Lexus has tried to satisfy luxury coupé and convertible shoppers simultaneously with the hardtop SC and IS convertibles since 2001.

That is until the folks in Japan decided to change their strategy to compete more directly with BMW, Mercedes and Audi in every segment. The result is the development of the RC.

Perhaps because Lexus decided against a 2-coupé strategy, as utilized by BMW and Mercedes, the RC is mix mash between the compact IS and the mid-sized GS — with a little bit of Lexus IS C tossed in for good measure.

In theory, the new coupé was also to serve as the basis for an all-new convertible. Unfortunately, the dealer network revolted and demanded another change in course, redirecting efforts into a 3-row crossover. As a result, the all-new RC is sold alongside the aging Lexus IS C convertible, a situation that’s unlikely to change for the foreseeable future. Fortunately for enthusiasts, Lexus developed their M4-fighter at the same time as the more pedestrian RC 350, otherwise the very-blue 467-horsepower RC F you see above may have met the same fate as the moribund convertible.

V8S2015-BRAND-Gen-2-Infographic-Banner-1200x6281

Guidelines for the new Australian V8 Supercar series outline specifications for its new cars, including an option to use smaller engines for the manufacturers who compete.

According to the racing series, the new platform “allows more flexibility in terms of body style and engine configuration, provided they comply with the regulations. The V8 engine, which has been mandated for more than 20 years, is also expected to continue as the dominant power plant of the sport.”

The guidelines allow for 4-, 6- or 8-cylinder engines, as long as they meet power specifications. The plans also call for a minimum noise limit of 85 to 95 dB. Take that, Bernie.

2015 Dodge Charger V6 AWD Rallye (9 of 13)

We just had a fight.

Scratch that. We were still having a fight. This was just the tense calm between volleys of verbal mortar fire. I won’t even tell you what we were fighting about. The subject was so stupid it would make my girlfriend and I both look like utter idiots — like those times when you shout at a character in a TV show to grow up and “just say you’re sorry already!”

Instead of doing what any rational human would do, I figured my only chance of peace was to escape the waves of relationship-drama ordnance. I grabbed the keys to this week’s Charger along with my vaporizer and fled the front line to regroup and regain my sanity.

2015 Chevy Silverado 2WD LT Crew Cab

Just a couple of months ago, GM quietly announced their factory 5 year/100k mile powertrain warranty was going to henceforth be downgraded to a 60k mile powertrain warranty because their cars are all fine now and customers don’t care about long-term warranties.

About 48 hours after this was announced, my wife found herself limping along the side of a major road in our 2010 Malibu with 90k miles on the odometer, engine revving, but little transmission of power taking place between the engine and the wheels.

Cadillac ATS-V

The ATS-V+ rumored by Motor Trend is definitely not happening according to Cadillac spokesperson David Caldwell. The proposed new model would encroach too much into CTS-V territory for comfort.

Here’s what happened overnight.

The 2016 Chevrolet Camaro was introduced May 16, 2015, at a special event in Detroit. The all-new muscle car is approximately 200 pounds lighter than the current model and offers more powerful V-6 and V-8 engines.

“From every angle, you’ll never mistake this for anything but a Camaro,” said Tom Peters, design director for the sixth-generation Chevrolet Camaro. That’s probably because it hasn’t changed that much, at least visually. Yet, under the skin, the new Camaro drops some 200 lbs thanks to its new Alpha platform bones and gains a new base engine – a 2.0L turbocharged Ecotec four-pot.

Could you/somebody please explain what a “flat plane crankshaft” is in the new Mustang GT350, and older Porsches and Ferraris?

I have seen numerous references to it online and in print but nobody, including Wikipedia explains it in non-calculus terms.

Hi Sajeev,

I saw your call for reader questions for the Piston Slap series, and as a diligent and loyal TTAC supporter/Kool-Aid drinker, I will do my best to do my duty (did I just recite the Boy Scout motto?).

You’ve been kind enough to respond to my previous question regarding the failing health of my wife’s Subaru Outback. By the way, in the spirit of CarTalk’s Stump the Chumps question follow-up feature, we ended up dumping the ailing Outback via Craigslist at a discounted price with a full-disclosure of all the mechanical issues (Love. It’s what makes a Subaru a Subaru…or something like that…). We got a 2nd gen Acura MDX and we actually love it. Take note Subaru.

Anyway, to my question: my daily driver is a 2007 4Runner with the lovely Lexus-derived 4.7 V8. The V8 part is important because in the 4×4 variant, as mine is equipped, the power is delivered to the road through a full-time 4-wheel drive setup, rather than the part-time 2H-N-4H-4L system found in the 4.0 V6 4Runner. We’ll come back to that in a moment.

Hey Sajeev, I got one for you.

Several engines nowadays are set up to operate on half their cylinders under light-load conditions. Would the design considerations for piston rings vary from those normally used for such cylinders that are only used part-time? The question arises in the context of a 2009 V6 Accord that is currently in the Honda dealer’s shop to have the piston rings replaced at the manufacturer’s expense to cure a continual oil consumption and spark plug fouling problem.
