There were two very interesting announcements – one very possibly game changing – from Chevrolet this week. Prefacing that the 2019 Chevrolet Silverado full-size pickup truck will offer eight levels and six powertrain combinations, they announced the debut of an all-new 2.7L I-4 Turbocharged engine and the introduction of Dynamic Fuel Management technology on certain 2019 Silverado trim level / powertrain combinations.
2.7L I-4 Turbo
First there were V8’s, then came the V6’s followed by V6 turbos and now a four-cylinder turbo engine is arriving in a competitive full-size pickup truck. Who would have thought just a very few years ago that we would see a ‘four-banger’ under the hood? Well now we are.
The all-new 2.7L in-line four-cylinder turbocharged gasoline engine just introduced by Chevrolet, is highly likely to change how we look at powertrain performance in the full-size pickup truck segment.
Chevrolet says the new engine development was a ‘clean sheet’ design effort to fundamentally change the powertrain dynamics in the lucrative and competitive full-size pickup truck segment. This is a truck engine – plain and simple – focused on delivering competitive payload/tow capability with more torque plus better fuel economy than competing products.
Compared to the current base Silverado 4.3L V6, the new engine weighs in 380 pounds lighter while delivering more horsepower and torque. The 2.7L Turbo delivers 310 horsepower (25 more than the V6) and 348 lb.-ft. of torque (43 more than the V6) with a torque band peaking in a low range of 1,500 to 4,000 rpm. For optimum performance, it will be mated to an enhanced 8-speed automatic transmission.
Not sure where this fit, but Chevrolet added that a 2.7L Turbo equipped 2019 Silverado will ‘sprint’ 0-60 mph in under 7-seconds.
The 2.7L Turbo features an aluminum block and cylinder head for reduced mass and a slew of new and innovative design elements and technology. Among them are Chevrolet’s first application of their Active Fuel Management (cylinder deactivation) system on a four-cylinder engine, an advanced design quicker-throttle response dual-volute turbocharger, continuously variable valve timing, dual overhead camshafts, variable-pressure oiling system, integrated exhaust manifold, direct fuel injection and an electric water pump.
We could spend a couple of paragraphs laying that all out for you, but the real issue will be how much and how well it actually hauls, with what fuel economy and at what price.
EPA fuel economy ratings and towing/payload capacities were not available at the time of this announcement. They, plus pricing, will come closer to launch.
When we get an opportunity to get behind the wheel of the 2019 Chevrolet Silverado equipped with the 2.7L Turbo, we will give you a further report on its performance.
The new 2.7L Turbo is scheduled to be available in Q4 2018. It will be standard on the LT and RST trim levels of the 2019 Silverado. It will not be available on other trim levels according to Chevrolet.
Dynamic Fuel Management
Though the latest big news from Chevrolet was the debut of the all-new 2.7L I-4 Turbo engine, it was also very noteworthy that an (also new) Dynamic Fuel Management system will be on updated versions of the 5.3L (8-speed automatic) and 6.2L gasoline engines for the 2019 Silverado.
Dynamic Fuel Management is the next generation of intelligent fuel management technology. The heart of the system is a sophisticated controller that continuously monitors the accelerator pedal. It runs a complex set of calculations – up to 80 times per second – to determine how many cylinders are required to deliver necessary torque. There are 17-cylinder deactivation patterns that the system can choose from to optimize fuel efficiency and power delivery at every speed.
The 5.3L V8 with DFM produces 355 horsepower and 383 lb.-ft. of torque and is matched with an 8-speed automatic transmission. The 6.2L with DFM delivers 420 horsepower with 460 lb.-ft. of torque and uses a 10-speed automatic transmission. The transmissions have been re-engineered such to maintain shift quality and efficiency during the continuous cylinder deactivation change process.
Both engines – with DFM – also feature driver-selectable stop/start technology to further enhance fuel economy in stop and go traffic.
Active Fuel Management (AFM)
Chevrolet’s proven Active Fuel Management system technology is included in the new 2.7L Turbo. It is the first application of the technology on a four-cylinder engine by Chevrolet. In the case of the 2.7L Turbo, the Active Fuel Management system shuts down two of the four cylinders under light load conditions to improve fuel economy.
Besides the 2.7L I-4 Turbo, the 4.3L V6, and 5.3L V8 (w/6-speed automatic) are equipped with AFM that – in their cases – shuts down to four-cylinders under light load conditions.
