A mix of dry and damp, tight bends and a narrow road should be challenge enough for a hot hatch with 316bhp to spill from its rear wheels. And if that sounds like a temptingly reckless number then you'd be right it's only 19bhp down on the output of the lately departed 1M Coupe, and the M135i's 320lb ft of torque is identical.

If it comes with the optional eight-speed paddle shifter of our test car, the 135i will zoom-flick, zoom-flick, zoom-flick through the gears to 62mph in just 4.9sec. Go for the six-speed manual and the time actually rises to 5.1sec because its wider spread of ratios are less speedily swapped.

Either way, this new three-door 1-series is eagerly, muscularly and excitingly quick with the potential, you may think, to become a flailing handful if you dare to meddle with the ESP button. But the first bold dive into a rain-sheened bend uncovers grip reserves far deeper than expected deep enough that when that DSC button is prodded for partial disengagement, it takes some lead-foot ambition to get the rear axle's wider 245/35 R18s to get a skate on, the slide part-managed by a brake-deploying virtual limited slip diff.

So it's pretty neat, controllable and reassuring, the more so because this rear-driver is quite a finely balanced tool, as proved by a too-fast arrival into a tight, low speed turn that fails to bring on any plough-on understeer. That said, you can expect to see plenty of the orange light that confirms an active ESP system, which is no surprise given all this energy and rear-wheel drive.

Perversely, it's best to experience all this in the Comfort setting of the £515 Adaptive M Sport suspension, an essential option. It softens off the electronic dampers and lightens the steering effort to produce a satisfyingly communicative, more absorbent chassis and best of all, usefully more feelsome steering. Of course, tripping the Comfort mode slows the shift times and the gearbox's willingness to hold a gear, but that's easily undone by sliding the gearlever to leftwards to Sport, which gets you a more eager gearbox.

The result is a an excitingly rapid drive that sits just the right side of hectic, the excitement of the six's keen blare built on by the 'box's light thumps in sport, the ra-ta-tat of the exhaust's over-run, the lightly clasping support of the seats and an excellent driving position. While some may desire the more uncompromising character of the 1M Coupe, the fact is that this M135i's ride is less maskingly firm, its steering more delicate and its character easier to live with. And it's also a whole lot cheaper, being almost £10k less.

Of course, you do without the some of the 1M's alloy suspension hardware and massive brake rotors although the 135i's enlarged blue-calipered discs are entirely effective but remember that the M135i rides on the latest 1-series platform besides benefiting from bespoke suspension geometry and its own springs, dampers, anti-roll bars and bushes.

More immediately noticeable M135i identifiers include a new front bumper unit with larger air intakes, a rear bumper with twin exhausts and 18in alloys, and tyres, that are wider at the rear. Inside you get leather sports seats (the UK won't be getting the appealing Alcantara/hexagon cloth mix of the test car, which seems a pity), a black headlining, an M footrest, blue accent stitching to the seats, patterned aluminium trim inserts and modified instrument faces. Not a huge amount of differentiation then, but enough to mark this 1 out as something sportier. The cabin is robustly constructed too, although it's not as finely, designed, finished or textured as the cabin of the latest Audi A3.

Much of the M135is's considerable entertainment repertoire is provided by the straight six. This Twinpower motor features a twin scroll variable geometry turbocharger, variable timing of both inlet and exhaust cams, variable valve lift and direct injection, these features managing to almost eliminate turbo lag. Indeed, you must actively search it out to find any, by shifting manually and having the revs build from 1000rpm to the 7500rom limit in second, say. Then you'll uncover a slower-moving tacho needle to 1300rpm. From this point the six has already reached its 320lb ft torque peak, this figure impressively maintained through to 4500rpm, although the revs don't rush at you until this peak has passed, the tacho needle performing a lightning flit to the limiter.

Throttle response is not as instant as you'll find in a normally aspirated M3, but it's sharp enough for most circumstances. Couple the six's breadth of urge to that eight-speeder, and you have a car that powers near seamlessly from a dawdle to its easily struck and restricted - 155mph maximum.

M division has tuned the 135i's exhaust to provide a smoothly busy soundtrack that makes paddling your way through eight ratios an absorbing business, even if the noise can turn slightly wearing. Happily it quietens off at a motorway cruise. And we suspect the same may be true of the ride, which showed signs of choppiness on Germany's mostly smooth roads.

2012 SLP GMC Sierra 1500 4WD Crew Cab SLT

After four days in this truck I began to feel something of an appreciation for how Genghis Khan must have felt as he charged into unsuspecting villages.

The 450 hp and 470 lb-ft of torque were intoxicating in this pickup, and the whine of the supercharger was a quick way to bring a smile to my face.

While docile under normal driving conditions, when dipping into the WEP War Emergency Power of the supercharger, the truck became even more enjoyable.

While the truck is no slouch, given its weight, the additional height from the off-road suspension and its oversize wheels, it feels much faster than a normal Sierra, but not as insanely quick as one would hope with the additional power of forced induction.

The TVS 1900 supercharger kit for the 5.3-liter gives you instant power when you tromp on the loud pedal. And loud it is, because with the addition of SLP exhaust tips, the truck has a burble and growl that makes a great addition to something with a high ride height and badges that say "supercharged" on the door.

Looking under the hood you can tell that this is no stock truck, despite being able to order the kit and products from the dealer without impacting the warranty.

But, the underhood finish of the kit leaves something to be desired. It looks both at home and not quite right. The kit would look better with a little less chrome and more flat accents; the shiny SLP air tube under the hood looks out of place.

The interior was the biggest letdown. Much to my surprise, the Katzkin interior treatment not only mixed two colors you shouldn't mix black and brown but it made it appear that the truck had far more miles on it than it actually did.

Judging from the play in the fabric and finish, I would have thought 30,000 miles had been ridden in the seats. Much to my horror, there were just more than 500 miles on the odometer when I grabbed the keys. I would have preferred the money be kept under the hood and the interior upholstery left stock.

The crew cab provided ample interior space for both front and rear passengers and for hauling groceries.

As I was in the process of moving, I filled the bed with my large items and hauled them to my new place.

The added height from the off-road suspension option worked well for setting and picking items up when loading and unloading.

Overall the truck is a lot of fun and useful if big trucks with big power tickle your fancy. The biggest problem I had over my time with it was keeping my foot out of the accelerator. While I was no fan of the interior appointments, I'll overlook it for the sound of the supercharger and the juvenile smile I often had.

An exhaustive introduction to the Ferrari FF

BY: Nic Cackett

An exhaustive introduction to the Ferrari FF is likely to be superfluous to even the most casual Ferrari fan so we'll only pause for a brief recap before getting to the nitty gritty of our first UK drive.

Launched around a year ago, the shooting-brake-styled four-seater offered buyers a first: a full-size Grand Tourer with a 651bhp V12 engine and, somewhat contentiously, four-wheel-drive.



The colossal, naturally aspirated unit is a direct injection descendant of the V12 that featured in the Enzo, but Ferrari's first production all-wheel drive system is an altogether more novel solution. When required by the front wheels, power is fed directly from the crank into a second, smaller gearbox located beneath the engine.

This transmission only has two forward gears, and because its ratios cannot replicate the seven-speeds of the main gearbox, the resulting wheel speed mismatch is managed by two continually slipping clutches. The main benefit of the system is that it offers all-wheel-drive traction (you'll doubtless have seen video footage of the FF ploughing through snow) without the normal weight penalty.

Ferrari claims its Power Transfer Unit adds just 45kg to model's kerbweight.

 The innovative packaging is not limited to underneath, either. As well as four perfectly chiseled sports seats the FF provides 450 litres of boot space - enough to put some family hatchbacks to shame.

The only thing it consumes more enthusiastically than people and luggage is fuel and air: up to 80 per cent of the engine's 504lb ft of torque is available from 1750rpm - use all 8000rpm and it will reach 62mph in 3.7 seconds, splinter 124mph in 11sec, and top out at a claimed 209mph.

The joint candidacy of Opel/Vauxhall Ampera and Chevrolet Volt, with 330 points, has been distinctly preferred by CotY 2012 Jury members, who put Volkswagen Up! second with 281 points and Ford Focus third, with 256.

Volt/Ampera offer is a mature product, after years of development and perfectioning by General Motors, and the first example of an electric vehicle with extended range. Others will come along this path. The concept, addressed to the fears of potential customers in front of an incipient recharging net of electricity for vehicles, implies energy generated on board, to continue the journey, once exhausted the rechargeable batteries. In the case of the Ampera/Volt, that means a 1.4 petrol engine working in semi-stationary regime. The balance between electric drive range and combustion-engine help takes in account the usually short daily displacements of the average car user. The electrical autonomy is rated at around 60 km with normal driving, then it comes the 1.4 to the rescue.

Viability of such approach, in a time when recharging possibilities on the road are limited, has been positively assessed by Jury members, who see in the Volt/Ampera a product better suited to consumers' needs than the conventional electric car. By the way one of those preceded the Opel/Chevrolet in the CotY title. In the early phase of distribution in Europe, Opel has reckoned to have around 7,000 firm orders of this model, in spite of a high price, somewhat moderated by public subsidies.

Some stringent crash test in USA recorded heat control problems in the battery pack, and the possibility of a fire. GM has thoroughly addressed the matter and applied new solutions, with better protection of the batteries and more efficient cooling systems, so customers can be assured.
