Who will be the first to transplant this into a classic Mini?!



"This is the all-new, BMW 1.5-litre, three-cylinder turbocharged engine. It will find its way under the bonnet of next year’s new Mk3 MINI.

Codenamed B38 (petrol) and B37 (diesel), it will come in petrol and diesel forms and is expected to be between five and 15 per cent more economical than BMW’s current N20 four-cylinder engines.

Built on an alloy block, the engine gets Valvetronic variable valve timing, a single turbo, 11.0:1 compression ratio and a longer stroke than the N20. It has been engineered as part of BMW future modular engine strategy, which sees all engines based on the same individual 500cc cylinder.

BMW says the petrol engine will develop between 40bhp and 66bhp per cylinder, giving the various versions power outputs of between 120bhp and 200bhp. The torque outputs are expected to be between 44lbft and 66lb ft giving a range of 132lb ft and 198lb ft.

The B37 diesel engine shares up to 60 per cent of its architecture with the petrol engine and can be made on the same production line. The diesel engine output will range between 100bhp and 181bhp and 166lb ft and 221lb ft of torque.

BMW is also preparing the B48, the four-cylinder sister engine of the B38. It is expected to power models including the next-generation MINI Cooper S, to be shown in late 2013. The engine is expected to produce in excess of 220bhp."

"The 2014 F56 hatch is the first of the next generation Mk3 MINIs and a precursor to replacements for all future MINIs. While it signals a shift away from unique MINI underpinnings and technology (most of the F56′s underlining structure, engines and electronics will be shared with a new line of front wheel drive BMWs) it also could usher new technology, performance and efficiency never dreamt of in a small car. In some respects one could even look at these changes and be forgiven in thinking the next generation MINI is about to get a little more “Mini” like."

That will be an awesome fit into a classic mini

[Mini_Magic]

What?! The classic mini never had a small engine. Sacrilege!

I have a 3 cylinder 660 cc with multi throttle control in my little Honda Beat. Gives me about 50mpg.

When I read about the Forumla Ford with a 3-cylinder engine on the Nurburgring I was hoping that the engine would be small enough to drop in to a standard round nose without body modification.

Now BMW are doing a 3-cylinder too I guess there are two chances that the engine will fit. Although Fords offering is a 1l I believe, which keeps with the Minis original small displacement. Could definitely be an interesting conversion.

[coopdog]

very expensive tho :/

The Ford 1-litre Ecoboost engine drives brilliantly ... and it is is about the size [and weight] of a briefcase underneath its ancilliaries!


ETA - it's a 1 litre, three cylinder engine, heavily turbocharged and apparently develops 125bhp.

Typical three cylinder engine noise, it sounds just like a V6 – or more accurately we now know that traditional V6s sound just like the doubled up three cylinders they are. The 1-litre Focus had thoroughly acceptable acceleration and performance for a blast round London suburbs driving one up. I could hear and feel the turbo come on boost a lot of the time and the trip computer from showed instant mpg readouts that jumped from 22 to 66 [to 99.9 on the overrun] but I think it would turn out to be pretty good on fuel – near to diesel mpg figures.

Sounds like we could be well on to a winner there. If it can even come close to fitting in the engine bay without modifications then I'll be planning to do one. Have to wait until it's been in production cars for a bit though so the engines become available second hand from written off vehicles and such.

125 bhp would be a tasty figure in a road Mini I'd say. Must be fairly economical too.

Do you have any links to more info about them?

I like the idea of pulling pistons & liners from a V6 exec saloon, that's priced itself into the scrappers early, to breathe new life into a couple of tired 3 cylinder engines. Assuming we're still allowed to open our own bonnets.

[redhotminilewis]

Driven the 1L turbo ford and its quick, very quick. My daily driver is a 3 cylinder 1L petrol corsa. Its not quick but defo nippy for the amount the car weighs. The engine is tiny when you open the bonnet, would easily fit in a mini. But im not chopping up my new 12 plate corsa to find out if its any good!

Me? No. FoMoCo will have lots though!

I merely took the keys to someone else's Focus Ecoboost courtesy car because I was fascinated what it would be like ... for the first time in a dozen years because I'm really not interested these days in borrowing other people's cars!

It had nicely weighted light steering and a responsive front end - because there's no weight over the axle - no torque, of course, and the performance and [probably] economy I would expect fom a lowish powered turbo diesel.

[sport2000]

I got a new focus aswell(drives very well) although mine is 2.0 tdi 163bhp titanium x version..
I've heard 1.0 turbo is pretty good from Ford..
Be interesting to see the 1.0L turbo conversion in a mini...

From Motoring File:
One of the biggest concerns about MINI’s upcoming three cylinder engine (after power) is sound. What do three cylinders sound like compared to the current four?
Based on first-hand experiences and the video after the break, pretty promising. The three cylinder has a healthy warble and sounds decidedly more aggressive than the current Cooper 1.6L four.

Keep in mind that we believe (thanks to several inside sources) that the N37 three cylinder will debut on the MINI One, One D, Cooper and Cooper D as the F56 Mk3 MINI launches late next year. The Cooper S will retain the Prince engine for the time being before eventually switching over.

As for transmissions, what we see below is a rear drive application of the 3 cylinder mated to BMW’s amazing 8 speed auto. What will the MINI have remains to be seen. But we believe it’s likely either an 8 or 9 speed lightening quick automatic with a six speed manual standard.

But how does it sound? Click through to find out.

Sounds good and looked like it pulled and revd well.
