The 2019 Silverado's 3.0-Liter Duramax Is Chevy's First I-6 Turbodiesel

The 2019 Silverado’s 3.0-Liter Duramax Is Chevy’s First I-6 Turbodiesel

Also the first I-6 since Chevy killed the Trailblazer in 2009.

Chevrolet is breaking the status quo with its all-new 3.0-liter inline six-cylinder Duramax turbodiesel. Announce in conjunction with the new 2019 Silverado 1500, this light-duty turbodiesel marks a few big milestones for the automaker. It breaks convention by avoiding the familiar V-6 design used by both Ford and Ram’s 3.0-liter V-6 turbodiesels.

First, the 3.0-liter I-6 Duramax is the first straight-six diesel engine Chevy has ever made, and second, it’s the first inline-six produced since the Chevy Trailblazer and its 4.2-liter Atlas I-6 ended production during the 2009 model year.

Chevrolet Cruze Diesel Sedan Becomes Most Efficient Non-Hybrid In America

Chevrolet Cruze Diesel Sedan Becomes Most Efficient Non-Hybrid In America

Finally a Cruze that’s supposed to burn oil!

The Chevy Cruze entered its second generation for the 2016 model year and came correct with a redesigned exterior that gives it a sportier look while maintaining the look of an everyday family sedan. Supported by an all-new architecture known as the D2 FWD, the new Cruze shed up to 250 pounds and gained an inch in the wheelbase department. The car itself is more aerodynamic, offers better fuel efficiency, and comes with extra space inside over the last-gen model. But, more important, was the new engine that displaces 1.4-liters and delivers 153 horsepower and 177 pound-feet of torque. That was the only engine on the list for U.S. customers… until now. Chevy has finally announced the diesel-powered Chevy Cruze, and it packs a fair 137 horsepower and 240 pound-feet of torque with a 1.6-liter four-banger in tow.

Power output isn’t the reason we’re here today, though. The reason we’re here today is that diesel engine can deliver an EPA-estimated 52 mpg on the highway when paired with a six-speed manual transmission. But, it’s not all peaches and cream here, as in-city driving is rated at just 30 mpg, giving this Cruze diesel with the manual an EPA combined rating of 37 mpg. There’s also Chevy’s new nine-speed automatic that manages to pull 47 mpg on the highway and 31 mpg in the city, also leading to a combined rating of 37 mpg combined.

As far as comparisons go, it won’t beat out your everyday hybrid in combined rating or city rating, but that figure of 52 mpg on the highway is better than that of the Toyota Prius C at 43 mpg on the highway, and the Volkswagen Jetta Hybrid, which achieves 48 mpg on the highway. The Prius Eco beats it out by just one mpg on the highway. Needless to say, this is a pretty big deal for Chevy customers who spend more time on the highway than anywhere else.

GM Officially Debuts Next-Gen 6.6-liter Duramax Turbodiesel

GM Officially Debuts Next-Gen 6.6-liter Duramax Turbodiesel

Only its displacement remains unchanged

The wait is over and the anticipation is now satisfied – GM has officially debuted its heavily revised 6.6-liter Duramax V-8 turbodiesel. Actually, “heavily revised” might be an understatement. GM says only the stoke and bore remain unchanged over the outgoing LML Duramax, letting the new engine retain the familiar 6.6-liter displacement. Nearly every other component is updated or completely new for the 2017 model year.

The benefit? An increase of 48 horsepower and 145 pound-feet of torque, along with cooler operating temperatures leading to increased durability during sustained high-load events, strong cylinder heads, a stronger main block, increased oil flow capacity, a new electronically actuated and controlled turbocharging system, and an acoustically tuned oil pan and valve covers that dramatically reduce engine noise.

“Nearly everything about the Duramax is new, designed to produce more torque at lower rpm and more confidence when trailering or hauling,” said Gary Arvan, chief engineer for the new Duramax. “You’ll also notice the refinement improvements the moment you start the engine, and appreciate them as you cruise quietly down the highway — with or without a trailer.”

The advancements allow the turbodiesel to generate 90 percent of its peak torque at only 1,550 rpm and maintain it through 2,850 rpm. It’s at 1,600 rpm that all 910 pound-feet is realized. Within that power band at 2,800 rpm, the engine reaches peak its horsepower of 445. This sustained torque curve gives the Duramax a wider power band for hauling and towing. The new torque spec represents a 19-percent increase from the previous engine. Despite the added power, the Duramax is 38 percent quieter at idle.

2016 Chevrolet Colorado Duramax Diesel

2016 Chevrolet Colorado Duramax Diesel

The time has finally come for General Motors to release the long-promised 2.8-liter four-cylinder Duramax turbodiesel in its Colorado and Canyon midsized pickup trucks. The engine has been on the books for production for the 2016 model year ever since GM debuted the trucks back in 2014.

Until now, the two trucks have utilized the base 2.5-liter four-cylinder and previously range-topping 3.6-liter V-6 gasoline engines as the only options. With the introduction of the “baby” Duramax, customers demanding higher towing, payload, and fuel efficiency numbers can opt for the new engine.

Chevrolet has set the diesel upgrade price at $3,730 more than the 3.6-liter V-6. The price includes some add-ons as well, making the cost seem more reasonable. A new six-speed automatic comes standard while 4WD models use a new transfer case. All Duramax Colorados get a diesel-exclusive exhaust brake and integrated trailer brake controller, along with all the emissions equipment that allow the engine to pass EPA standards.

Those trailering aids help boost the Colorado’s max towing capacity by 700 pounds to 7,700 pounds on 2WD models. Those equipped with 4WD can tow a maximum of 7,600 pounds. In keeping with the theme, a frame-mounted two-inch receiver hitch comes standard with the Duramax.

Chevrolet says the new Duramax won’t sacrifice comfort for capability. The transmission includes a new style of torque converter called a Centrifugal Pendulum Vibration Absorber. Long story short, the CPVA keeps excessive vibrations out of the driveline and therefore out of the cabin.

The EPA fuel economy estimates have not been released yet, but expect the Duramax Colorado to achieve better than 30 mpg on the highway. Sales should begin by late summer 2015.

2014 Chevrolet Colorado ZR2 Concept

2014 Chevrolet Colorado ZR2 Concept

It’s no secret the truck world is excited to have GM’s new midsize truck twins, the Colorado and Canyon, rolling off the assembly line. Their smaller size means they’re easier to drive while their powerful gasoline powertrains keep all the truck-style capabilities truck buyers demand. Chevrolet also knows truck buyers sometimes venture off the beaten path, so good off-road abilities are a welcomed feature. But even the mighty Z71 package can’t match this bad boy; Chevy’s latest concept, the Colorado ZR2.

The truck comes complete with tons of trail-ready hardware, an extra-wide stance with beefy tires, a built-in winch, electronic locking differentials front and rear, and best of all, GM’s new, 2.8-liter, Duramax, four-cylinder turbo-diesel. The baby Duramax is an engine GM promised right off the bat with the new Colorado and Canyon trucks, though it wouldn’t become available until the 2016 model year. Well the time has come for the engine to make its big debut and we can’t think of a better way than in this purpose-built concept truck.

While few concept vehicles actually made it to production, this one might actually have a shot. Chevy offered the ZR2 off-road package between 1994 and 2003 on the S-10 pickup, the predecessor to the Colorado. Now in its second model year, 2016 would be a perfect chance to add such a package to the Colorado’s trim packages, especially considering the Z71 is no longer the stand-alone off-road package it used to be.

Updated 01/23/2015: We’ve added a series of new images from the car’s official debut at the 2015 Detroit Auto Show. Check the new images in the "Pictures" tab.

2015 Chevrolet Silverado HD

2015 Chevrolet Silverado HD

With the roaring applause still ringing from the recent debuts of the new Silverado 1500, Tahoe and Suburban, Chevy has also revealed a pretty heavy revamp for the 2015 HD trucks.

It seems the welcome reception to all the other new bow-tie trucks means that the 2014 model year will be very short: GM pushed up the HD release so that all the factories can start gearing up for the hugely-improved 2015 model year.

The Silverado HD’s updates are actually much deeper than a facelift, with the largest changes coming from the way the truck body is mounted to the chassis. Chevrolet is using a new type of welding process that is claimed to bring large increases in all rigidity measurements, cabin quietness and ride comfort.

The new nose looks pretty great, actually. Chevy’s truck styling really seems to be very sharp these days. Projector beam lamps update the nose nicely, and a very dramatic chrome grille has far more shaping and structure to its surfaces.

Improvements to cooling and aerodynamics are hoped to increase highway fuel economy, where these big trucks really start to chug whatever fuel they are using at anything over 65 mph.

Drag is a real issue for these machines, and any HD owner will tell you that an 80 mph cruise with a trailer can switch the usual miles per gallon into gallons per mile.

Other changes include a totally-redesigned cabin, seats, infotainment and the whole vehicle’s electronic architecture. Under the hood, the engines are carryover but have a new engine management that integrates all the towing and stability safety features into its work flow.

What this boils down to for buyers is better economy, higher payload and towing stats, and a cruise control that now claims to be able to maintain a set speed even with a heavy trailer out back. Previous cruise controls for many cars will pop off and fail to keep a speed if doing so might make the engine stall.

So it is truck-a-palooza at Chevrolet this winter. Are buyers swayed by the new looks and vastly superior cabin?

2014 Chevrolet Silverado HD

2014 Chevrolet Silverado HD

Comfort, safety, durability and power are the key reasons for upgrading to these heavier pickups from the lighter-duty Silverado that is all new for 2014. Even while the new model has projector beam headlights and some extra cabin tech, the 2500HD and 3500HD Silverado’s continue with only detail tweaks for 2014.

These updates include a new standard final drive ratio that boosts tow ratings by 4,500 pounds across the board, and a bi-fuel option that can run on normal gasoline or clean and affordable natural gas at the flip of a switch.

Chevy packs quite a bit more strength into these $30,000 to $50,000 2500 HD and 2500 HD trucks than their fierce cross-town rivals from Ford’s F-Series Super Duty and the Ram Heavy Duty choices.

These trucks have the rock-solid capabilities that would have required heavy and specialized machinery even a few decades ago.

Two quite unique buyer groups exist for these Texas-sized pickup trucks: people using the HD trucks to earn a living, and people who are so rich that they need to be able to transport all their toys to the cabin - at the same time. 10,000-plus tow maximum’s and fifth-wheel trailer hitches available, the Chevrolet Silverado HD trucks are only of the only ways to move a family of five, a large boat, jet ski’s and ATVs all in one trip.

These days, the Silverado HD series will happily get filthy doing the dirty work from dawn to dusk, but it must also deliver far more friendly service during the off hours. This is the real challenge for all pickup trucks, and the Chevrolet Silverado 2500HD and 3500HD models are the last bastion of (at times) crude manners and a DuraMax exhaust drum wider than a telephone pole.

All this while hauling its drivers and their families in comfort and safety that still seems unimaginable at times for these big work trucks. Is the aging 2014 Silverado HD still up to the task in the face of a revised 2014 Ram Heavy Duty with an air suspension in back? How about versus the ever-popular Ford F-Series Super Duty and its huge cabin space?

2014 Chevrolet Cruze Clean Turbo Diesel

2014 Chevrolet Cruze Clean Turbo Diesel

Clean diesel models are just starting to make their ways into the North American market, and to everyone’s surprise, they do quite well. For example, in the first quarter of 2012, sales numbers were up 35 percent when compared to the same period of 2011 and things continue to improve.

From all diesel units sold in the USA last year, a total of 44 percent where the Jetta TDI, a pretty astounding result, considering this is about half of a market that offers about 25 clean diesel models, which experts say will double by 2017.

The first step into this direction was made at the 2013 Chicago Auto Show where Chevy unveiled the new Cruze Clean Turbo Diesel - not a big surprise considering Cruze is Chevrolet’s hottest-selling sedan.

The model will be put on sale at a starting price at $25,695, which is about $2,500 more than the Jetta TDI priced at $23,055.

UPDATE 6/12/2013: This review has been updated with the official drivetrain specifications. Surprisingly, they are significantly better than GM originally estimated.

International Engine of the Year Awards are in and BMW Cleaned House

International Engine of the Year Awards are in and BMW Cleaned House

TV buffs get the Emmys, movie buffs get the Oscars, and music lovers get the Grammys; so, where does that leave us gearheads? Well, the International Engine of the Year Awards, of course, and the 2012 results are hot off the press!

Ford took home the top prize of International Engine of the Year, with its 999 cc engine found in the European Focus. This engine, despite its petite size, cranks out 125 PS (123 horsepower) and manages to squeeze out 56.5 mpg. The 1.0-liter engine didn’t win a close battle either, it took home top honors by a full 113 points. Points are accumulated based on fuel economy, smoothness, performance, noise and drivability and each engine can only receive 15 of each voter’s total 25 points to give. Needless to say, that was quite a landslide victory.

That’s not the biggest news though, as BMW brought home top honors in four different categories. Bimmer took home the 1.4- to 1.8-liter prize with its 181-horsepower, 1.6-liter engine found in the MINI Cooper S. In the 1.8- to 2.0-liter class, BMW took first prize with its 241-horsepower, 2.0-liter twin-turbocharged four-pot. In the 2.5-liter to 3.0-liter class, BMW wrapped up top honors with its bi-turbo 3.0-liter six-cylinder engine and its 335 horsepower. Last, but certainly not least, BMW took home 1st place in the 3.0- to 4.0-liter class with its 414-horsepower, 4.0-liter V-8 engine.

Despite all of the accolades, the highest mark that BMW achieved in the Engine of the Year award was 5th place, with its 2.0-liter twin-turbo four-banger.

2012 Chevy Aveo Diesel gets extreme MPG, but what about the U.S.?

We all understand that the European market was the first to really get nailed with high gas prices. They were paying over $5 per gallon while the U.S. market still was just cresting the $2 per gallon mark. This forced the European market to start accepting smaller and less desirable vehicles in hopes of getting better economy, while folks in the States continued to drive Hummers and other large SUVs.

Now that gas is hitting $4 per gallon, the U.S. buyers are starting to become more receptive to smaller cars with upwards of 40 mpg capabilities and hybrids cresting the 50 mpg mark. However, we are still left out in one market, the ultra economic clean diesels. The latest one is the 2012 Chevrolet Aveo, which is known as the Sonic in the U.S.

In the U.S., the highest mpg available on the Sonic is 40 mpg and that is the optional 1.4-liter turbocharged engine, which we have our doubts if any normal driver can actually hit 40 mpg in this car. In the U.K., the Aveo has several four-cylinder engine options, including a 1.2-liter gasoline, 1.3-liter diesel, 1.3-liter Eco Diesel, and a 1.4-liter. The highway fuel economy on these engines is 68.9 mpg, 83.1 mpg, 85.6 mpg, and 62.7 mpg, respectively.

None of these engines would make the Sonic a speed demon, like the relatively quick Sonic LTZ and its 1.4-liter turbo engine, but will Chevy ever bring these engine options to the U.S. market? We understand that diesel fuel is not as readily available as regular gasoline, but they certainly give the U.S. buyer an option other than hybrid or electric, which have technologies that could end up requiring rather pricy repairs in the future.

We’re not singling out Chevy here, as Ford has its ECOnetic system getting 65+ mpg in a Ford Fiesta. Our best Fiesta gets an arguable 40 mpg on the highway. Seemingly every car company has a super-Eco diesel engine in its European lineup, but we have yet to see one in the U.S. We think the time has come for one to show up.
