The automotive world is full of trends and copycatting, so it is not uncommon to see drivetrain modifications start off small and explode as the years progress. If you think back, you will find one of the slower growing trends in automotive history was fuel injection, as it dates way back to 1925, then by 1940 it was first made electronic by Alfa Romeo engineers. In 1952, it became commercially available via Bosch, but only a few automakers made use of it. By the early-1990s, all but a handful of cars had electronic fuel injection of some sort.
On the opposite end of the spectrum, in terms of rate of growth, is the elimination of V-8 engines in favor of more practical turbocharged V-6 engines. The Ford F-150 has been on the front lines of this V-8 abandonment front and it all began with the elimination of all but two V-8 engines in 2011 – the 5.0-liter V-8 and 6.2-liter V-8 were the only 8-cylinder engines available – and replacing them with a series of V-6 engines, including: a high-output non-turbo, a 302-horsepower 3.5-liter, a 302-horsepower 3.7-liter, and a 365-horsepower twin-turbocharged 3.5-liter V-6 engine.
Since this successful introduction of forced-induction V-6 engines by Ford, seemingly every company is working on a hot turbocharged V-6 to replace their V-8 engines. The most notable is General Motor’s work on a 3.0-liter turbocharged V-6 for its upcoming Escalade redesign and the new Silverado and Sierra. There are also whispers of a twin-turbo V-6 for the Camaro. Dodge has fallen behind, but has turned its focus more toward making its existing V-8 powered trucks more economical, but will eventually have to switch to turbo power to keep pace.
So the question on everyone’s mind is how do these turbo charged V-6s stack up to the aging and fuel-hungry V-8s?
