In depth: Acura’s 2.3L turbocharged I-4 engine
Filed under: LA Auto Show, Tech, Acura
When Acura designed the RDX, they wanted to give it a lightweight mill that was powerful enough to compete in a class rife with six-cylinder power. A V6 would provide the desired output, but it would add too much mass over the front axle, so instead, Acura decided to slap a turbo onto a four-cylinder and boost output accordingly. Honda, Acura’s parent company, has developed some of the best performing four bangers in terms of horsepower-per-liter, so the engineers had a lot of innovation at their fingertips. The package put together for the RDX is a 2.3-liter inline-four, complete with Honda’s i-VTEC variable valve timing and creating 240 hp at 6000 rpms and 260 ft-lbs of torque at 4500 rpm. Thanks to the addition of the turbocharger, it makes more torque than any other engine in Acura’s lineup — not a huge feat considering that most of Honda/Acura engines are devoid of any low-end grunt. The engine also features some economical innovations to keep the RDX’s price tag from skyrocketing, so when we found this engine on display at the Acura booth at the 2007 Los Angeles Auto Show, we thought a closer look was in order.

Those who have followed the post-Talladega Nights stream of Formula One refugees fleeing to NASCAR will be happy to learn that former F1 driver Juan Pablo Montoya has been awarded Rookie of the Year in the Nextel Cup.


I think I’m going to puke if I have to go to another auto show that promotes itself as the “greenest” of them all. These days, every auto show in the world claims to be more concerned about the environment than any of the others. And LA was no different. 
For years it seems there was an unwritten code among law enforcement officers stating that you didn’t give a shield-wearing brother a speeding ticket unless his offense was really bad. Beyond bad, even. That doesn’t appear to be the case in the UK, as the chief constable of South Yorkshire has been cold busted going 90 in a 60 mph zone. Britain’s Med Hughes stepped down after the court hearing, but he states that his decision to walk away from his post of top traffic cop had nothing to do with his lead foot. To that we give a hearty, “Right-o, chap.” Of course as the chief constable, Mr. Hughes preached stringent speed enforcement. The now-defunct top traffic cop even lobbied for hidden speed cameras, which would keep speeds down while racking up big fine money for the department. If Mr. Hughes feels slighted or embarrassed, we’d like to welcome him to our club. As members, when we get tickets we pay the fine, collect the points, and generally suck it up. We’re sure he’ll find it all to be very novel.
