Skyactiv-X Engine Debuts Inside 2019 Mazda 3 This Month

Mazda is bringing its new Skyactiv-X engine, hyped as a major leap forward in internal combustion engine technology, to the Los Angeles Auto Show and the end of the month. Wedged inside the new Mazda 3 sedan and hatchback, the powerplant uses “Spark Controlled Compression Ignition,” which is said to combine the efficiency of a diesel unit with the performance of a gasoline mill. The manufacturer claims fuel economy improvements of more than 30 percent over a standard gasoline engine of the same displacement.

Assuming Mazda meets that mark, it’s a petty impressive feat. The 2.0-liter four-cylinder will debut along with the 3’s new platform in L.A. at the end of the month.

Mazda: "Impending Death of the Internal Combustion Is Overrated"

If you were among America’s 1.4 million new vehicle buyers in July 2017, there’s a 99-percent chance your new vehicle requires fuel. Although the vehicles that run off the electric grid are linked to $7,500 government tax credits, they form barely more than half of one percent of the U.S. new vehicle market.

Mazda, you’ll recall, doesn’t sell any electric vehicles in the United States. Mazda doesn’t sell any vehicles with a plug. Mazda doesn’t even sell any hybrids.

So it’s not surprising that Robert Davis, former Mazda USA senior vice president of operations who’s now in charge of special assignments, candidly laid out the case for the internal combustion engine yesterday at the CAR Management Briefing seminars in Traverse City, Michigan.

“The internal combustion engine has a strong future role in transportation,” Robert Davis says.

Don't Go All Hybrid/Turbo/Electric/Fuel Cell Just Yet - Toyota V6 And V8 to Gain "Dynamic Force" Camry Engine Tech

Forget hybrids. Set aside, for this moment, plug-in hybrids as well. Ignore the EV hubbub and the pie-in-the-sky hydrogen fuel cells. While you’re at it, remove turbochargers and their accompanying displacement reductions from your memory, too.

The naturally aspirated internal combustion engine has legs. The proof is in the 2018 Toyota Camry’s 2.5-liter Dynamic Force four-cylinder. With no hybrid assist, no turbos, no cord that plugs into your garage wall, and no futuristic fuel source, the new Camry 2.5-liter produces 206 horsepower and hits 41 miles per gallon on the highway on regular 87 octane.

That’s 16-percent more power 24-percent more highway mpg than the 2017 Camry’s 2.5-liter four-cylinder. With improvements in conventional, naturally aspirated, gas-fired engines occurring in such leaps and bounds, it’s no wonder Toyota has bigger plans for the Dynamic Force blueprint.

Study Shows Nearly Nine in 10 Americans Want Better Fuel Economy, But There's a Problem

A recent study from Consumers Union — the public policy and advocacy division of Consumer Reports — shows continued interest among U.S. residents in seeing automakers improve fuel economy figures, even as gas prices remain fairly low.

While this should come as a shock to no one, nearly nine in 10 surveyed consumers agreed automakers should continue improving fuel efficiency standards on all vehicles. As well, only 30 percent believed manufacturers actually cared about lowering fuel costs for their customers.

This might be true but, then again, why would automakers do such a thing when the general populace has essentially turned its back on economical passenger cars? With little incentive to sell them, especially if the Trump administration alters 2025 emission targets, any top-tier automaker focusing exclusively on building MPG-focused automobiles would be placing itself at major financial risk.

The survey indicated fuel economy as the area perceived to possess the most room for improvement in modern vehicles. However, consumers have not used their wallets to bolster economy car sales. There appears to be a disparity between what the public claims to value and how it actually behaves. At a minimum, consumers may have misunderstood everything it would take to see fleet-wide fuel consumption decline. If they want to see higher MPGs, they’re going to have to make some sacrifices and the survey doesn’t allude to that fact.

Swedish Company's Camshaft-free Piston Engine Already Has a Customer

A Swedish company with close ties to a hard-to-spell supercar maker has thrown a wrench into the automotive world, unveiling a production-ready piston engine that doesn’t use a camshaft.

Developed by FreeValve AB, which isn’t a Nordic Lynyrd Skynyrd cover band, the new engine technology ditches a camshaft for other modes of valve actuation, gaining power and efficiency in the process. Unlike some other touted internal combustion engine advancements, this technology already has a customer.

Volkswagen Shows Off Its New Gasoline-Powered Gas Engine That Runs on Gas

Diesel? What’s that?

Volkswagen is embracing a far less controversial type of fuel with its new 1.5-liter TSI engine, unveiled yesterday at the Vienna Motor Symposium.

The ultra-efficient four-cylinder uses variable turbine geometry (VTG) in its turbocharger to generate peak torque at a low 1,300 rpm, then maintain a flat torque curve until about 4,500 rpm. This leads to fuel economy gains and a better driving experience.

Waissi Engine Update: The Differences Between Waissi and Bourke Engines

Bourke Engine (click for animation)

In a comment to my post last month about Professor Gary Waissi’s new piston engine that has no connecting rods between the pistons and the crankshaft, one of our readers asked about similarities to the Bourke Engine, invented by Russell Bourke. Based on the diagrams of the Bourke motor, that seemed like a good question, so I asked Prof. Waissi about it. I received his reply today. Waissi said that while there were similarities between his engine and Bourke’s, there were also substantial differences, resulting in the Bourke engine having more operating friction. Dr. Waissi also said that he hoped to have a two-cylinder prototype of his own design assembled and running by the end of this year. Waissi’s response after the jump.

  • Inside Looking Out Why EBFlex dominates this EV discussion? Just because he is a Ford expert?
  • Marky S. Very nice article and photos. I am a HUGE Edsel fan. I have always been fascinated with the "Charlie Brown of Cars." Allow me to make a minor correction to add here: the Pacer line was the second-from-bottom rung Edsel, not the entry-level trim. That would be the Edsel Ranger for 1958. It had the widest array of body styles. The Ranger 2-door sedan (with a "B-pillar", not a pillarless hardtop), was priced at $2,484. So, the Ranger and Pacer both used the smaller Ford body. The next two upscale Edsel's were based on the Mercury body, are were: Corsair, and, top-line Citation. Although the 1959 style is my fav. I would love a '58 Edsel Pacer 4-door hardtop sedan!
  • Lou_BC Stupid to kill the 6ft box in the crewcab. That's the most common Canyon/Colorado trim I see. That kills the utility of a small truck. The extended cab was a poor seller so that makes sense. GM should have kept the diesel. It's a decent engine that mates well with the 6 speed. Fuel economy is impressive.
  • Lou_BC High end EV's are selling well. Car companies are taking advantage of that fact. I see quite a few $100k pickups in my travels so why is that ok but $100k EV's are bad? The cynical side of me sees car companies tack on 8k premiums to EV's around the time we see governments up EV credits. Coincidence? No fooking way.
  • EBFlex "I'd add to that right now, demand is higher than supply, so basic business rules say to raise the price."Demand is very low. Supply is even lower. Saying that demand is outstripping supply without providing context is dishonest at best.
