Currently reading: Frankfurt motor show 2013: BMW 4-series
Production version of BMW 4-series revealed; full technical specification, data, price and on-sale details

This is the definitive production version of the BMW 4-series coupé, the successor to the highly regarded BMW 3-series coupé and rival to the Audi A5 and Mercedes-Benz C-class coupé.

Seen at the Frankfurt motor show today, the new two-door is set to go on sale in the UK on 5 October, priced from £31,575 for the entry-level 420d SE.

Three turbocharged engine options will be offered initially, with three more forced-induction units to follow. In a move aimed at providing the 4-series with a broader appeal than its predecessor, there will also be a choice of either rear or four-wheel drive in selected models. Five trim levels - SE, Sport, Modern, Luxury and 
M Sport - will be offered. 

The BMW 4-series, first previewed in concept form at the Detroit motor show in January, is based on the same platform as the 3-series saloon. Changes to its chassis, including wider front and rear tracks and suspension lowered by 10mm, provide it with a lower and wider appearance that befits 
its sporting brief. It also has 
the lowest centre of gravity of any BMW on sale. 

At 4638mm in length, 1825mm in width and 1362mm in height, the 4-series coupé is 26mm longer, 43mm wider and 16mm lower than its 3-series coupé predecessor. The wheelbase is up by 50mm to 2810mm, and the front and rear tracks are extended by 45mm and 81mm to 1545mm and 1593mm respectively.

The jump in size sees kerb weight increase marginally, with the base 420d hitting the scales at 1450kg, or 30kg more than the old 320d coupé, in six-speed manual guise.

The three launch engines will be a 181bhp four-cylinder turbodiesel in the £31,575 420d, a 242bhp 2.0-litre four-cylinder petrol in the £32,595 428i and a 302bhp 3.0-litre six-cylinder petrol in the initial range-topping £40,795 435i.

Three more engines will be added one month after launch, including a 181bhp 2.0-litre four-cylinder petrol in the 420i, a 254bhp 3.0-litre six-pot diesel in the 430d, and a 309bhp version of that unit in the 435d.

The 435d will be sold exclusively with BMW’s xDrive all-wheel drive system. In November, xDrive will also be offered as an option on the 420d and 420i models. Rear-drive is standard on all models except the 435d. A six-speed manual gearbox is standard on all models except the 430d and 435d, which come with an eight-speed automatic transmission. The eight-speed automatic is an optional on the rest of the range.

The most potent launch model is the 435i which, when equipped with the optional eight-speed automatic, has a 0-62mph time of 5.1sec. The most efficient is the auto-equipped 420d, with economy of 61.4mpg and CO2 emissions of 121g/km. Performance and economy figures and pricing have yet to be confirmed for the models arriving in November.

Back to top

Crowning the line-up from late next year will be the M4 coupé. Power is set to come from a heavily tuned, twin-turbocharged version of BMW’s 3.0-litre in-line six-cylinder petrol engine, which is claimed to deliver around 440bhp. 

BMW is already talking up the dynamic properties of the 4-series, suggesting it is one of the sportiest cars in its line-up. The springs, dampers, camber angle and axle responses have all tuned for increased agility, while BMW is claiming a 50 
per cent front/50 per cent rear weight distribution.

Stylistically, the new car borrows heavily from the latest 3-series saloon, particularly at the front end. As tradition dictates, the long doors are frameless. Despite the visual similarity to its four-door sibling, the body is unique. 

Inside, the 4-series coupé shares its dashboard, instrument binnacle and centre console with the 3-series saloon. But with steeper screen angles and front seats that are more contoured and set lower than its four-door sibling, it offers a more overtly sporting driving position. The longer wheelbase increases rear legroom, but the boot volume is just five litres greater than the 3-series coupé, at 445 litres. 

Standard equipment includes heated leather seats and a 6.5in colour screen with BMW’s iDrive controller. All versions except the base SE get 18-inch alloy wheels and sports seats. The M Sport trim includes adaptive dampers, which are available as an option across the rest of the range.

Repeat Buyers?

I am a "repeat Buyer" - 9 BMWs in 18 years! But, I will NOT be buying a 4 Series as there are no naturally aspirated 6 cylinder models available. A turbocharged N20 4 cylinder is no replacement for a straight six. No sale to me then. After 18 years and 9 BMWs I will not be having a 10th. Bad move BMW by adopting the Audi approach to power and emissions you have removed my reason to buy your cars.

To be honest.............

Too many options,the M style alloys are the worst i've seen from BMW,the vent behind the front Wheel arch is very Jaguar-esque,and the badge above it is sooo 1980's,some of the interior options are a bit eye popping shall we say too,the over all shape of the car is good,i just hope Diesel isn't the popular choice,most BMW dealers a crammed with them.But, i agree,it will sell , to repeat buyers of the marque.

So I guess you won't be able

So I guess you won't be able to buy an M3 Coupe anymore. From a branding perspective, this seems a bit of an odd one. 

A few years ago, BMW were streets ahead of the game with their co2 output and official mpg to power ratio. They are no longer. BMW are in danger of losing their mass appeal as a 'drivers marque' unless they make some major alterations to their approach. But as someone pointed out earlier, perhaps they only care about numbers now.

Great point from Rich_uk

Well if they are playing the numbers game then they are taking a huge gamble. Audi know how to play it far better than they do, and BMW would be badly diluting their USP - "The Ultimate Driving Machine."  Yes I know that this applies only to their position vis-a-vis their immediate competitors, but still a proud boast to be able to make.
