They might do that again, but I think the V12 diesel is next. That is going to be some engine.

BMW really needs to step up their direct injection technology. They've had it in the 760 for a couple of years but no other engines have it, aside from the new twin turbo inline 6. I can't believe that the 5.0 V10, with all it's high tech bits, didn't get this technology. It sure could use it. Driving around town and getting 12 mpg is not fun. MB's V6 is sure going to be one sweet engine.

Now we know MB's answer to BMW's new bi turbo 3.0

Can't wait until they put it in the SLK350. Going to be a hoot to drive!

Like I said... CLS350 will get it first. (Mercedes CLS350 CGI debuts in Geneva)

Here are some engine pics from the CLS350 press kit @ WCF

What the hell funny lookin' spark plug is that!

Erm, actually no, it's not that unusual on closer inspection. It all the chrome that confuses one...

Expect to see it soon. To me, it's a response because of the 300-hp+ Lexus V6.

CGI = Stratified Charged Gasoline Injection I believe, but I couldn't find a verification online.

I think both these engines still use old fashioned fuel injection.

World Premiere Of The Mercedes CLS 350 CGI
Posted on February 24, 2006 at 8:40 AM CST


Mercedes has announced today that they will be adding a new member to the CLS family, dubbed the Mercedes-Benz CLS 350 CGI.

The CLS 350 CGI, or Stratified-Charged Gasoline Injection if you're not the acronym-inclined type, is the world's first vehicle sporting a petrol engine to feature piezoelectric direct injection and spray-guided combustion. Or in plain English, the CLS has more power than a conventional CLS 350, all while consuming less fuel. Sound too good be to true? Read on my skeptics.

First up are the specs. The Mercedes CLS 350 CGI is powered by a 215 kW/292 hp six-cylinder engine, producing a torque rating of 365 Newton metres at 3000-5100 rpm. That's an increase of 20 horsepower over the conventional-injection V6 and four percent more torque. In terms of on-road performance, the CLS 350 CGI accelerates from 0-60 in 6.7 seconds, and can reach an electronically limited top speed of 155 mph.

But as promised, despite the impressive numbers, the newest CLS also features improved fuel economy. According to the press release, owners can expect to see approximately 9.1 - 9.3 liters per 100 kilometers, which gives the four-door coupe a range of about 807 kilometers on one tank filling (80 Liters). For my American readers, that comes out to about 25 mpg, an increase in fuel economy of up to 15% over the standard CLS 350.

This all sounds great, but you're probably wondering how the new injection system works. Fear not my faithful readers, here's a small sample from taken the press release that should give you some idea of what's going on under the hood: "The main advantage of the CGI engine lies in the stratified operating mode from which it takes its name. During this mode the engine is run with high excess air and thus excellent fuel efficiency. Now, thanks to multiple injection, it is for the first time possible to extend this lean-burn operating mode to higher rpm and load ranges too. During each compression stroke, a series of injections takes place, spaced just fractions of a second apart. This has the effect of significantly improving mixture formation, combustion and fuel consumption. While stratified charge operation was previously only possible in the low part-load range, the new Mercedes direct-injection engine can still operate in this lean-burn stratified mode at speeds in excess of 120 km/h."

Got that? Of course, that's only a small sampling of what you can expect from the press release. Read on for photos of the new Mercedes CLS 350 CGI as well as the new CGI injection system, and check out the press release for the full details of how the new system works. Oh, and by the way - expect to see the CLS 350 CGI hitting European shores in the second quarter of 2006.

Enjoy.
