New basic engines, new top-of-the-range model BMW M135i and BMW xDrive.

The range of five-door BMW 1 Series models is being supplemented by various new engine options. The BMW 114i will be launched as early as in July of this year. The new basic BMW 1 Series power unit delivers 75 kW/102 hp with a maximum torque of 180 Nm. Average fuel consumption is just 5.5 litres/100 km and CO2 emissions are only 129 g/km. The BMW TwinPower Turbo four- cylinder petrol engine combines a Twin Scroll turbocharger with Valvetronic, Double VANOS and High Precision Injection. The result is an engine that is both powerful and extremely efficient, also thanks to further BMW EfficientDynamics measures such as the Auto Start Stop function, Shift Point Indicator in conjunction with the six-speed manual transmission and brake energy regeneration.

The BMW M135i is the top-of-the-range version of the BMW 1 Series. This distinctively dynamic vehicle is an integral part of the new product category BMW M Performance Automobile produced by the BMW M GmbH. It is positioned between the most powerful BMW series production models and thoroughbred BMW M vehicles. BMW M Performance power units generally boast a noticeably higher performance than the previously most powerful engines of any BMW series and have M-specific characteristics in terms of suspension setting and visual appearance, though without any limitations in terms of suitability for everyday use. Heart of the new BMW M135i is the straight six-cylinder petrol engine with Twin Scroll Turbo technology, Valvetronic, Double VANOS and High Precision Injection. It delivers 235 kW/320 hp and a maximum torque of 450 Nm, power transfer being effected by the six-speed manual transmission fitted as standard. As a result, the most powerful BMW 1 Series offers dynamic performance worthy of a sports car. The vehicle sprints from 0 to 100 km/h in a mere 4.9 seconds. Top speed is 250 km/h (electronically limited). In spite of these figures, the BMW M135i has an average fuel consumption of just 7.5 l/100 km as per the EU test cycle, and a CO2 emission level of around 175 g/km. (All figures apply to the five-door BMW 1 Series with an optional eight-speed automatic transmission).

For the first time in the history of the BMW 1 Series, the intelligent four-wheel drive system BMW xDrive will be available as an option. The models BMW 120d xDrive and BMW M135i xDrive are due out shortly.

Interesting re 114.

[Pavit]

Now the F20/F21 series gets even more better, all it lacks is the overhead display :-)

[eezzee]

In the photos of the rear there's a hole where the central parking sensor ought to be. Presume camera location rather than fallen out.

Anybody know if this 114 engine is the same as 116 only with different software?

[1thomas]

In other words: No news at all. All those facts were published by the end of may.

[ovekvam]

The turbo and intercooler is the same on the 114i and 116i (and 118i), so I think it is only software. I guess a chip tuned 114i should deliver close to 200 hp...

This is what I'm hoping/thinking. Save some on purchase and on annual taxes but install some software, maybe Hartge can help here

[1thomas]

The complete engine has the same number for the 14i and the 16i, but the 18i has another one, so it ought to have some different parts. The 14i is most likely just a detuned 16i (as its with 16d/18d, maybe even 14d/16d ede), but the 18i has at least some different parts. Still the 16i is probably good for 18i default-power, as should be the 14i then.

[ovekvam]

I have noticed that the tuners with connections to BMW (typically the ones that will provide you with warranty) will give less power in a tuned 116i than a 118i. Probably just politics.

It seem Hartge offer about 170hp for 116 and a bit over 200 for 118 so I would also assume there is some differences between the engines. But I'm hoping 114 is the same as 116. Have to wait until someone offers tuning for the 14.

[1thomas]

If you check the numbers for a replacement-engine for the 14i and the 16i are identically (same part number).

Selected 114i -> engine -> engine/rmfd-engine:
http://realoem.com/bmw/showparts.do?...&fg=05&lang=en

There are 2 numbers listed for the engine, both are used in the 114i, 116i and 316i:
http://realoem.com/bmw/partxref.do?l...rt=11002317934
http://realoem.com/bmw/partxref.do?l...rt=11002320930

That makes it effectively the same engine. With Turbo and Intercooler being identical too, that leaves us basically with a software-detuned engine.

[ovekvam]

But I haven't found any part differences on engine related parts between 116i and 118i either. I wonder what's different.

Interesting.

In South Africa (I know this differs between countries) our Motorplan offering covers literally everything except tyres for 5 years, and any tuning voids this. Sure, the tuner will give you a warranty, but not for 5 years.

I guess it's all down to priorities, but here, very very few people touch cars under Motorplan, it's just too risky.

[1thomas]

Over here 5 years of warranty is just not happening, not with BMW or Merc or any similar brand . Law says 2 years is required, thats what most offer. You can get extended warranty for x amount of money at most brands though.

It has been discussed before in the forum.
The only difference is the downpipe.
It's strange though because
I've heard that it might change perf. figures around %3-5.
%20 is too dramatic for this kind of variation.
And then there is the tough ECU & piggy-back issue.
I'm no expert on matter but it's rumoured that
a piggyback module (almost all bmw upgrades (hartge, acs, kelleners) because it's tough to break bmw ECU...)
does not yield same as a complete ECU REMAP.
My formula is %10 politics, %5 mappability, %5 downpipe

BMW SA also offer the same 2-year warranty, but our Motorplan is essentially a 5 year maintenance plan honoured by a separate subsidiary of BMW SA. It's the most comprehensive maintenance plan in the industry though, covering every single mechanical component, even including wiper blades, batteries, bulbs, etc. Pretty much the only two things they don't cover is fuel and tyres.

The effect of Motorplan is that cars even 4 years old are essentially no-risk 2nd-hand purchases, as you can buy it, and get any issues sorted out by BMW with practically no questions asked. Of course, as soon as BMWs here are out of Motorplan, their value drops drastically. This is why owners only start modding once out of MP, because the knock in value taken if you void your MP by modding (BMW SA are very strict) is just not worth it.
