6.6-Liter Durmax Diesel Torque Monster

Like the horsepower wars that "The Big Three" are involved in with their cars, the war to build a heavy-duty truck that can push the limits and take the crown for the biggest and best torque ratings are very much alive as well. 

For 2017, GM decides it's time to refresh and toughen up their 6.6-liter Durmax diesel engines for their Chevrolet Silverado and GMC Sierra HD trucks. The extra boost in power will provide the already stout HD trucks with 455-hp, up from last year's 397-hp. And the new torque ratings for the Durmax will be boosted up to 910-lb.-ft. of torque, a bump from the 765-lb.-ft. of torque from the previous year.

90% of this new found torque can be available at a very low 1,550-rpm, helping you take off from a dead stop very effortlessly even when towing an extraordinary amount of weight.  

  • The refreshed Durmax gets its power from a mound of new and beefed up engine components:
  • Turbocharger 
  • Cylinder Heads
  • Pistons
  • Connecting Rods
  • Crankshaft
  • Venturi Jet Drain Oil Separator

The Venturi Jet Drain Oil Separator uses boost from the turbocharger to suck more oil back into the sump, ensuring the oil doesn’t get in places it’s not supposed to go. GM also strengthens up their notorious Allison six-speed transmission to help deal with the new torque numbers, making the Durmax HD trucks more powerful and durable than ever. 

Along with all of the beefed up new components, the Durmax will also be able to run on B20 fuel, which is a mix of 20% Biodiesel and 80% conventional diesel fuel. 

So how does the 2017 Durmax setup match-up with the other competitors? The Ford Super Duty 6.7-liter Powerstroke diesel puts out 440-hp, but the Ford still takes the torque crown for 2017 with 925-lb.-ft. of torque. The Ram HD sports an inline six-cylinder diesel that puts out 385-hp with a very stout 900-lb.-ft. of torque, not bad for a six-cylinder. 

Since it doesn't seem like the competitiveness for big torque numbers is going to go away anytime soon, one would have to suspect that the possibility of seeing these HD trucks coming in at 1,000-lb.-ft. of torque+ very soon, is very real.

2014 Chevrolet Cruze Diesel Sales Are Down


It's been almost a year now since the 2014 Chevrolet Cruze Diesel went on sale, the first diesel passenger car that General Motors put on the market since 1986. 

General Motors had high hopes for the Cruze with the European turbodiesel engine, which was designed to compete with the well-established Volkswagen Jetta TDI. The Jetta and the Cruze are the only two competitive diesel compacts that are on the market today. 

So far General Motors has sold roughly 300,000 Chevy Cruzes for 2014, but only 5,974 (2.0 percent) were diesel models. Since GM was hoping on about 10 percent sales, the number is not a good number considering the Jetta TDI has sold 46,409 in the same period of time. But it should also be noted that one of the problems that the Cruze Diesel suffers from is the lack of marketing support it receives opposed to the already well-established Jetta Diesel.

Power Ratings
One thing the Cruze does have going for it is it has more power than the Jetta. The it is fitted with a 151-horsepower 2.0-liter turbocharged diesel engine, which produces a substantial 264 lb-ft of torque. The only available transmission is a beefed-up six-speed automatic; unlike the diesel VW Jetta, there's no manual gearbox offered.

The current Jetta TDI has a 140-hp 2.0-liter turbodiesel that produces 236 lb-ft of torque. It should be noted, however, that Volkswagen is about to fit a new line of more powerful diesel engines across its entire small- and medium-size car range.

Fuel Economy 
The Cruze Diesel is rated at 33 mpg combined (27 mpg city, 46 mpg highway). That's higher than the Cruze Eco automatic, at 31 mpg combined (26 mpg city, 39 mpg highway) but lower than the automatic version of the VW Jetta TDI at 34 mpg (30 mpg city, 42 mpg highway).

To boost its fuel economy, the diesel Cruze also adopts some elements of the high-efficiency Cruze Eco gasoline model, including automated grille shutters that block airflow through the engine compartment at higher speeds to reduce aerodynamic drag.

What People Are Saying
The Cruze Diesel has received mixed reviews. It gets praised for its quietness, smoothness on the highway and a lack of noise, vibration, and harshness, but it's also been dinged for slow response and uneven power in stop-and-go city and suburban driving.

The 2014 Chevy Cruze Diesel isn't cheap. It's priced at $26,695 including delivery--or about $600 more than a Volkswagen Jetta TDI fitted with an automatic.

Compared to the comparably equipped gasoline version of the Cruze with 2LT trim level, there's a $2,400 additional cost to get the diesel.

Buick Looking Into The Future

 Image result for buick enclave

Buick has made some great accomplishments in the past few years, that includes the refreshed 2014 Regal. Which starts out at $31,560, and packs the standard 259-hp, 2.0-liter four-cylinder engine—an upgrade over the previous and optional original engines—paired with a six-speed automatic transmission.

Some luxuries you can opted for are a remote start, dual-zone climate system, heated front seats, a sunroof and 18-inch wheels.

But Buick is thinking of another way outside of their usual luxury options and stylish looks draw in customers. The 2013 Encore was an awesome crossover for Buick, but it did lack one feature, that is power. 138 hp just was not enough for a bigger vehicle like the Encore, but its overseas cousin, the Opel Mokka, which was recently introduced with a 1.6-liter four-cylinder engine (with both gas and diesel variants) could find its way into Buicks line-up.

The Buick Verano, a close relative of the Chevy Cruz, could also be a good candidate for a diesel motor coming up in 2014. Either way, a more powerful diesel motor with good gas mileage could be just the attribute that Buick needs to separate itself from companies like Cadillac, Volkswagen, Audi and Mercedes-Benz, etc. -- and bring in new customers.
