Autonews.com has a few new details (more confirmations than anything) on the upcoming range of 3 cylinder engines. For some background BMW will be releasing a family of 3 Cylinders in the upcoming 1 and 3 Series along with the next generation MINI. The engine will use twin-scroll turbo technology first seen by BMW on the Prince series of MINI engines currently found in all MINI models. But the 1.5L 3 Cylinder will produce as much power with substantially more efficiency as compared to the current 1.6L four cylinder MINI engines.
Marketed as TwinPower, the technology is coupled with direct gasoline injection and Valvetronic fully variable valve management for a thoroughly efficient yet powerful package. Look for the first in the series of new engines to be released with the new 1 Series this fall. From there look for it to go into the 3rd generation MINI and then the BMW 3 Series F30 (all in late 2012).
We expect power to range from 120 hp to 180 hp in the 3 cylinder range and (as we already know) up to 240 hp in 2.0L four cylinder trim.
<p>I’m excited to hear what one of these sound like, and how it performs, but I believe the 4 cylinder should never go away. Heck, it would be nice to jam 5 or 6 cylinders in there, if only to smooth things out, but I know that won’t ever happen.</p>
<p>Doesn’t matter to me how many cylinders there are. All that matters is the power delivery (not just peak power), smoothness, fuel economy, and cost of maintenance.</p>
<p>Given the number of coolant thermostat failures on MINI, why nbot go the whole hog and make them air-cooled? There is enough BMW motorcycle engine technology to do this role.</p>
<p>What are the drawbacks of reducing to 3-cylinders? Doesn’t it reduce an engine’s smoothness and add more stress to all the other components, resulting in more breakdowns, etc.?</p>
<p>Does this mean the “base” engine for all future MINI Coopers is going to be a 3-cylinder?</p>
<p>My fear is it will just become another “extra cost option” added to the configurator.</p>

<p>i like the sound of the 2.0 liter 4 cyl more than the the 180hp 3 cyl.</p>
<p>I’m excited to hear what one of these sound like, and how it performs, but I believe the 4 cylinder should never go away. Heck, it would be nice to jam 5 or 6 cylinders in there, if only to smooth things out, but I know that won’t ever happen.</p>
<p>“We expect power to range from 120 hp to 180 hp in the 3 cylinder range and (as we already know) up to 240 hp in 2.0L four cylinder trim.”</p>
<p>Does this mean there will be a 2.0L 4 cylinder trim on Minis’?</p>
<p>3 cylinder have a much sportier sound than 4 cylinder… Flat-6-like ;)</p>
<p>Doesn’t matter to me how many cylinders there are. All that matters is the power delivery (not just peak power), smoothness, fuel economy, and cost of maintenance.</p>

<p>My fear is it will just become another “extra cost option” added to the configurator.</p>
<p>Is this engine part Peugeot, or will it be pure BMW?</p>
<p>You have to keep in mind that future motors won’t be as reliable as they were in the past !</p>
<p>It cannot be worse than the actual 4 cylinder though (high pressure pump, chain belt…)</p>
<p>wouldn’t it be cool to see a really small inline 6? I say squeeze a 1.5 I-6 in the MINI engine bay!</p>
<p>More cylinders would be regression, more consumption
The future says LESS</p>
<blockquote>My fear is it will just become another “extra cost option†added to the configurator.</blockquote>
<p>Actually, I’d fear the 4 cylinder would be the extra cost option.</p>
<p>I just hope the 3 cylinders mill will not sound crappy.</p>
