ASAFE BET

摘要

There has been one consistent criticism of the 2014 GMC Sierra and its Chevrolet twin: GM played it safe on drivetrain technology. 10 take such a conservative approach to a key component has led critics to infer that the whole truck was an exercise in doing the bare minimum, and, as such, wouldn't be competitive with the latest and greatest from Ford and Ram. Those inferences are wrong. It says something about the quickening pace of automotive technology development that direct injection is viewed as plebeian and passe. The fact is, GM's EcoTec3 engines may look similar, but are big improvements on a tried-and-true formula. The first-ever production, direct-injected, pushrod engines offer better power and fuel economy, GM says, and to prove it, GMC took us "glamp-ing"-glamorous camping.
