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.

General Motors announced Monday a new trim for the 2016 Buick Encore that will use a new 1.4-liter turbocharged four, which will be the first application of a new global-engine platform. The car will go on sale this fall.

According to GM, the new mill produces 153 horsepower and 177 pound-feet of torque — an 11 percent gain in power and 20 percent gain in twist over the 1.4-liter turbocharged engine currently doing duty in the cute ute. The two engines share only similar displacements. The current mill is rated at 138 hp and 148 lb-ft of torque.

There’s also a new Encore trim called Encore Sport Touring and it has a spoiler and 18-inch wheels and body-colored door handles and back to the engine.

The late Gore Vidal was fond of saying, “Gratitude can be a complicated thing.”

He was right. Whether you are a hater, or simply a chronic critic, the act of complimenting those who follow the beat of a different drummer is usually not within the tip of the human tongue.

We want things our way… and sometimes we’re just plain wrong.

In the eternal quest to adhere to “sustainability”, Lamborghini will apparently be fitting the Aventador with a start-stop system and cylinder deactivation. Am I the only one that finds the recent trend of eco-friendly supercars ridiculous?

The Environmental Protection Agency’s fuel economy testing system is notoriously weak, relying on self-reporting for the vast majority of vehicles, and exhibiting vulnerabilities to “gaming.” But rather than attacking each others’ EPA numbers, automakers seem to have agreed that it’s best if everyone does their best to juice their own numbers and allows the imperfect system to limp on. But over at Automotive News [sub], we’re hearing what could be the first shots fired in a new war over EPA ratings, as Product Editor Rick Kranz reveals that an OEM is starting to complain about another OEM’s fuel economy ratings. He writes:

An executive of one U.S. automaker suggests there might be some sleight of hand going on and that the EPA is not catching the offenders.

The issue: There’s a noticeable difference between the mpg number posted on some cars’ window sticker and an analysis of the data submitted by automakers to the EPA.

Ruh-roh!

According to a study by the Consumer Federation of America (PDF), relatively low gas prices haven’t done much to change consumer trends towards more fuel-efficient vehicles. This revelation comes amid claims that small car demand was artificially inflated by high gas prices and increased truck production from General Motors. The survey asked respondents to rate the importance of gas prices, global warming and US dependence on Middle East oil over the next five years, with 76 percent reporting “great concern” for gas prices and energy independence.
