How does 306PS in a 4-seat coupe the size of a Golf grab you?

And not any old 306PS engine, but ‘engine of the year': BMW's sensational twin-turbo 3.0 litre straight six that's both benignly tractable and very, very fast.

Over the last year BMW has been turning its slow selling sow's ear of a 1-Series into something of a silk purse. First we saw the three-door hatchback version with it's Efficient Dynamics 118 diesel that has since been developed to limbo under the 120g/m CO2 limit that gets it into London for nothing from next February and cuts the annual tax bill to £35.

BMW 1 Series Coupe (2008 – 2013) handling and engines

And as well as the 2,979cc 306PS petrol engine you can also have it with two 1,995cc diesels, one of which offers a respectable 177PS and the other a jaw-dropping 204PS. Yes, indeed, the first production diesel delivering more than 100bhp per litre (even after you convert 204PS to 201bhp).

The E82 is shorter than the E92 at 4,360mm against 4,590mm (which works out at 9" shorter). But, strangely enough, it's not significantly lighter. The E92s weigh in at 1,420kg to 1,570kg and the E82s at 1,450kg to 1,560kg.

So, not surprisingly, while 0-60 comes up in a seriously quick 5.1 seconds, that's actually no better than the 335i coupe.

50 - 75 in 4th is 5.0 seconds. 50 - 75 in 5th 6.0 seconds. It gets a move on for sure. Combined mpg is a useful 30.7. And while you're stuck with £400pa tax from next year with the 335i, the 135i emits only 220g/km so escapes with £210.

It's also a fair bit cheaper at £29,745. But it's a bit more edgy to drive than the 335i.

There's no option to the 215/40 R18 front and 245/35 R18 rear Bridgestone runflats, apparently developed specially for the car. You feel everything though them but as well as that get tossed about by cat's eyes, grids and manhole covers that the 335i absorbs. And this isn't helped by the quick rack but overlight and feel-free steering, a bit like the Z4 M's.

Of course you can make astonishingly quick progress and the car's extra sensory electronics do a fantastic job keeping you on the road. But it just isn't as much pleasure to drive as an E92. It's not as comfortable either, for me, at least. The seats seem to be designed for people with longer backs then mine or narrower shoulders. I didn't fit the mould.

I suspect I'd have been completely won over by the 204PS 123d on its slightly more absorbent 205/50 and 245/45 R17 runflats. Its 0-60 of 6.8 seconds is all you really need, and its potential 54.3mpg swings the argument completely. So does its price of £24,855, as long as you go for the SE and don't opt for the M Sport that brings with it same the bigger, lower profile tyres and stiff suspension as the 135i.

But I just didn't have time to wait my turn for that one.

In all E82 coupe's favour, though, is the decent size 370 litre boot and the fact that four normal sized people fit inside comfortably with plenty of head and legroom.

And if you really want to pull your costs back, yet still drive an impressively quick BMW, the £21,585 177PS 120d ES even scrapes into the £140 - £150 Band D tax bracket.

Next year they're cutting the tops off so you can have E83 convertibles. These will be much cheaper than the E93 electric folding hardtops and, with the 135i engine, just as quick.

And at the Tokyo Show they also revealed a sexy tii version. So it all makes sense.

That comes in white, of course. The best colour.

The standard specification includes 17-inch Star-spoke light alloy wheels, front foglights, heated exterior mirrors and windscreen washer jets, Network cloth upholstery, Sport multi-function leather steering wheel and Sport seats. All Sport models are priced at the equivalent ES price and offer customers £1,075 of added value.

December 2010

BMW 1 Series M Coupé announced at £39,995, UK deliveries from May 2011.

The sporty character of the BMW 1 Series M Coupé is expressed by a dramatic exterior design, with widened wheel arches, exclusive 19-inch Y-spoke M alloy wheels, and dual chrome tailpipes. A discreet spoiler lip generating additional downforce and a rear apron with side openings echoing the look of the front air intakes ensure the look of sporting intent matches the model’s sporting ability. L-shaped rear light clusters with two light banks fed by LED units complete the M car look. Exterior paint finishes are Alpine White non-metallic, Black Sapphire metallic and the exclusive Valencia Orange metalic.

The BMW 1 Series M Coupé is fitted as standard with twin corona bi-xenon headlamps, and LED-fed positioning lights. A hallmark M-branded feature is the elongated chrome gill element on the front wheel arch, while the door mirrors are from the BMW M3, but tuned for the specific aerodynamic characteristics.

The standard sports seats in Boston leather feature Kyalami orange stitching and offer both driver and front passenger excellent lateral hold. The interior is exclusively modelled for the BMW 1 Series M Coupé, with an M leather steering wheel and the use of Alcantara with Kyalami orange contrast stitching on the door trim, door inserts, handbrake and gear lever gaiter and instrument binnacle cove. The M logo is also embossed in the front of the headrests.

The new BMW 1 Series M Coupé has a high revving, in-line six-cylinder engine with twin turbocharger, direct injection technology and double VANOS variable valve timing to develop a maximum output of 340hp. Such performance equates to a highly desirable car that takes just 4.9 seconds to accelerate from zero to 62mph. The BMW M tuned twin-turbocharger technology used consists of two relatively small turbos which, because of their low inertia characteristics, are active even at low engine speeds, ensuring no turbo lag, yet a peak power output which is achieved at 5,900rpm.

BMW 1 Series M Coupé 340 500* 4.9 155** 29.4 224

Note: *With overboost. **Electronically-limited.

The great flexibility of the 2,979cc engine means that maximum torque of 450Nm is produced from as little as 1,500rpm. A flat torque curve for swift in gear acceleration sees peak torque maintained up to 4,500 rpm. This figure can be increased by another 50Nm when the car is under full throttle by means of an overboost function. With this performance the BMW 1 Series M Coupé will blast to 62mph from standstill to an electronically-limited top speed of 155mph. In fact, such is its stunning performance and handling, it is expected to be significantly faster around the Nürburgring Nordschleife than the previous generation E46 BMW M3.

The engine control system of the car allows two differing performance curves: in standard mode the BMW 1 Series M Coupé offers a more torque-orientated, flexible character to the engine’s performance delivery, while in M Dynamic Mode (MDM), activated by a button on the steering wheel, engine speeds rocket instantly, accessing the highest power levels as quickly as possible.

The cooling system of the BMW 1 Series M Coupé has been designed for constant high load, high speed track driving, through the use of an additional separate radiator and a specific air duct to deal with the increased thermal stress which can occur when driving in a particularly sporty style on the race track.

The efforts made in optimising performance and efficiency are also reflected in a newly developed dual-mass flywheel. Its lightweight construction benefits the engine's efficiency and it also has an increased solidity which is able to cope with the six-cylinder engine’s high level of torque.

In addition, EfficientDynamics measures such as brake energy regeneration and needs-based control of auxiliary units ensure that recorded combined fuel consumption is 29.4mpg and CO 2 emissions are 224g/km.

The BMW 1 Series M Coupé is only offered with a six-speed manual transmission, specially designed to work with high-torque engines. This newly developed transmission is operated using a very short-shift M gearshift lever.

The chassis of the BMW 1 Series M Coupé has been tested using BMW M GmbH's racing-oriented development process, and uses numerous key components, originally conceived for the BMW M3, have been modified for use in this car.

The latest M car weighs a trim 1,495kgs courtesy of extensive use of aluminium. The double pivot front axle and the five-link rear axle are made almost entirely of aluminium. Tubular stabilisers, axle links made of forged aluminium and aluminium shock absorbers round off the lightweight construction concept. With chassis technology derived directly from motor racing, a power-to-weight ratio of 227hp/tonne has been achieved. The footprint of the car is bigger than a standard BMW 1 Series Coupé with it being 55mm wider than the BMW 135i Coupé. The width of 1,803 mm is the result of optimisation of the front and rear axle to enhance driving dynamics.

As standard, BMW 1 Series M Coupé comes with Variable M differential lock, compound brakes, DSC with MDM and M Servotronic. The Variable M differential lock responds to differences in rotational speeds in the rear wheels, redirecting torque within a fraction of a second for optimum traction and maximum thrust on slippery surfaces and when accelerating out of bends.

The M-specific compound high-performance brake system of the BMW 1 Series M Coupé uses inner-vented and perforated discs with a diameter of 360mm at the front and 350mm at the rear, providing impressive stability even under extreme stress, as well as being extremely light.

Rack-and-pinion steering is fitted with Servotronic hydraulic power steering while the Dynamic Stability Control system that includes elements such as an anti-slip control function (ASC), the brake assistant Dynamic Brake Control (DBC), a drive-off assistant, Cornering Brake Control (CBC), an anti-fading function and a dry brake function is also standard. The driver can activate M Dynamic Mode (MDM) on the instrument panel, raising the point at which the driving stability control system intervenes.

The BMW 1 Series M Coupé comes with an extensive range of standard equipment, including 19-inch Y-Spoke alloy wheels, two-zone air-conditioning, cruise control, BMW Radio Business with MP3-capable CD player and six speakers. It also has a Boston leather interior with Alcantara trim with Kyalami orange stitching in the cabin.

Optional extras include Comfort Access, Harman Kardon Surround Sound System, Professional Navigation system with hard drive storage, Adaptive Headlights and High beam Assistant.

The BMW 1 Series M Coupé goes on sale in May 2011 priced at £39,990 OTR

December 2010

BMW 1 Series Coupé and Convertible ranges received a number significant modifications and upgrades that make them more desirable and efficient.

Both models differentiate themselves from previous incarnations by way of a new front bumper with redesigned fog lights and redesigned Halogen headlights with an ‘eyebrow’ element. When Xenon headlights are specified this ‘eyebrow element features an LED illuminated light bar. At the rear the headlights have also been changed with a more detailed appearance.

However, the greatest change to ES, SE and Sport models is that they now come fitted with an Aero Curtain – a feature that channels the airflow around the front of the car to reduce aerodynamic drag, thereby increasing efficiency. Wheel arches are one of the main areas of aerodynamic drag and the Aero Curtain is BMW’s innovative solution to reduce this inefficiency. Derived from race technology, air is routed into two ducts in the front apron which then flows out of a narrow opening at high speed in the wheelarch. This jet of air effectively covers the side of the front wheels like a curtain and thus reduces turbulence.

As a result, CO2emissions have been lowered throughout the range, with the 118d now rated at only 118g/km, while all 2.0-litre petrol versions have CO2emissions of 155g/km or below.

As with all BMWs, the 1 Series Coupé and Convertible also come with a raft of other EfficientDynamics measures: Auto Start-Stop is fitted to all petrol and diesel models (excluding versions with automatic transmission), while Diesel Particulate Filters, Brake Energy Regeneration, Electric Power Steering (excluding 135i), Intelligent Alternator Control and Optimum Shift Indicator for manual models are all standard throughout the range.

All BMW 1 Series Coupé and Convertible ES models come as standard with 16-inch alloy wheels, Dynamic Stability Control, Halogen headlights, MP3 playback capability and rear seat easy access system. Sport models have as standard 17-inch star-spoke alloy wheels, Sport multi-function leather steering wheel and front Sport seats – almost £1,200 worth of equipment that is currently offered for no additional cost over an ES model. SE models get rear Park Distance Control (PDC), front fog lights and automatic air conditioning with two-zone control.

All M Sport models, in addition to SE models, come with 17-inch light double-spoke style alloy wheels, door sill finishers with M designation, chrome front exterior trim, high-gloss Shadowline window surrounds, M aerodynamic bodystyling, M Sport suspension, Run-flat tyres, Sport seats and M Sport multi-function leather steering wheel.

BMW 135i M Sport versions add twin black-chrome exhaust tailpipes, a unique M aerodynamic package, M Sport suspension with 135i-specific calibration, hydraulic power-assisted steering, rear spoiler and up-rated high-performance braking system.

The new BMW 1 Series Coupé and Convertible go on sale March 2011, with prices starting from £21,960 OTR for the BMW 118d ES Coupé and £24,245 for the 118i ES Convertible.

Numerous problems with 42k mile 2011 BMW E82 118d

N47 M Sport Coupe bought September 2014: Needed new clutch and DMF, then new timing chain, then an injector seal. Now clutch is juddering again and drver's electric window intermittently won't close.

What to watch out for

Repeated coil and injector problems on 4-cylinder petrol engines from 2007.

24-01-2012:

DMF problems increasing on 118d and 120d, manifesting itself in clutch judder. BMW at first offers a software upgrade to increase idle revs, then, if that does not work, will replace the DMF and clutch of cars still under warranty with a flywheel and clutch of a new design.

Significant numbers of high pressure fuel pump failures on 135i in the USA. See link: www.n54tech.com/forums/showthread.php?t=14650 BMW initially "blamed" "ethanol" or "poor quality" gasoline in the U.S. for these failures. In fact, BMW HPFP failures are well documented in Germany (even with their "superior quality" gasoline), Australia, Asia, South Africa, etc. Some of these countries have never used ethanol in any of their gasoline..... HPFP Part Numbers 1. 13-51-7-537-320 2. 13-51-7-585-655 3. 13-51-7-592-881 4. 13-51-7-596-123 5. 13-51-7-594-943 6. 13-51-7-613-933 7. XX-XX-X-XXX-402 8. 13-51-7-616-170 9. 13-51-7-616-446.

Timing chain failures becoming increasingly common on N47 2.0 litre diesel engines subject to extended oil change regimes. Can occur from about 5 years old and from about 90k miles. From 50k miles onwards, best to change the oil every 10k miles maximum.

Seems to be a continued problem with 2nd generation N55 135i/335i models. Engine warning light coming on, car breaking down. Engine running rough and going into limp mode. Diagnostic told the techs to replace a fuel injection valve. Unfortunately, the same problem exists so they're back to troubleshooting with BMW NA with no end in sight. ECU reprogramming to fix the problem reduces low down torque and engine response. 9 weeks later, no better. Dealer has no answer apart from offer of a performance kit or £1,600 compensation. An American report states: "while the engine itself has so far proven reliable, there have been the occasional problems with the ECU cutting power to the motor. There have also been reports of oil coolers inadequately cooling the engine if the 335i is driven very aggressively in a track environment. The installation of an aftermarket oil cooler solves this problem." The N54 sequential twin turbo engine was replaced by the N55 single turbo engine with the same power but emitting lower CO2 in late 2010.

Problems with 44k mile 2008 135i Coupe bought privately in September 2014 include: Bonnet lock had stopped working, £99.94 - Jan 15. Then, the water pump went, taking out the thermostat as well. By the time they suggested a further engine oil service and the brake fluid service too, the bill came to £1,281.32. This was in April 2014. Now, in August, whilst driving along, the car just ground to a halt. Under diagnostics (thanks to the RAC for swift pickup), ownerinformed that three injectors have stopped working and the suggested "barest minimum" solution has come to £1,484.67. That was to replace 3 injectors, but the service desk suggested replacing all 6 at over £2,000.

2008 BMW 118i convertible with 17k miles left standing in a garage for a year after which it required four new injectors at £250 each, plus a new ECU at £900. Dealer told customer its diagnostics could not determine which injector was faulty or even if the faut was with the ECU.

What does the BMW 1 Series Coupe (2008 – 2013) cost?
