From £29,7008
The range-topping version of the BMW 4-series — the 435i — offers huge performance and poise
19 July 2013

What is it?

The BMW 435i is the nearest you’ll get to an M4 for the best part of the next year. 

It’s powered by the only six-cylinder TwinPower engine in the launch line-up (the 428i and 420d are both four-pot motors). The range-topping unit develops 302bhp between 5800 and 6000rpm, but more importantly, as we shall see, 295lb ft between 1200 and 5000rpm.

Read our review of the BMW 4 Series 440i M Sport here

With the eight-speed automatic gearbox fitted to our test car, it will accelerate to 62mph in 5.1sec, which is 0.3sec faster than cars with a six-speed manual, but 0.2sec slower than the forthcoming 435i xDrive. Top speed is limited to 155mph.

The 4-series has a wheelbase lengthened by 50mm over the 3-series saloon. It is also 26mm longer and has a track widened by 45mm at the front and 81mm at the rear. The roofline is 16mm lower and the ride height is reduced by 10mm, meaning it has the lowest centre of gravity of any current BMW.

BMW has changed the settings of the springs, dampers and camber angles and strengthened the front section, meaning that the 4-series is 60 per cent stiffer than the old 3-series coupé.

BMW is keen to distance the 4-series from the 3-series coupé, despite the obvious similarities. The styling is, to these eyes, rather handsome. The wide rear wheelarches are a particular high point, and BMW says it’s the first time one of its mid-size coupés has made such a focal point of its hips.

The interior also bears more than a passing resemblance to the Three. Again, some effort has been made to set it apart, with a dashboard colour palette not available to saloon buyers, door cards featuring a stretched design, and a character line that runs from the dash into the rear compartment. The rear seats are sculpted to appear as two separate seats and have integrated headrests, like those fitted to the 6-series.

The front seats are arranged slightly lower than in the 3-series, to offer a more sporting driving position. Space in the front is ample, and an increase of 13mm of rear legroom gives a decent amount of space, even if headroom is slightly lacking.

What's it like?

Quite a lot like a 3-series, actually. It is imbued with the same level of balance, poise and delicacy that made the current 3 one of a handful of cars to score Autocar’s full five-star rating.

The 3.0-litre twin scroll turbocharged straight six offers thumping performance. With the automatic gearbox tested here, it is just 0.3sec slower to 62mph than an E92 M3 coupé with a manual gearbox. And turbo lag? Forget it. Power peaks at just 1200rpm and plateaus until 5000rpm. Its straight-line urge is strong and relentless.

Less impressive is the engine note. There’s rather too much of it at tickover – its actually rather like a diesel – and not quite enough when winding on the power. Still, the engine offers a smooth power delivery and impressive flexibility, which makes it a devastating point-and-squirt overtaking machine.

Its frenetic pace is matched only by the speed of the gearshifts from the eight-speed auto. It is a masterclass in automatic transmissions, this. It’s virtually impossible to wrong-foot it, and the quality of shifts in Sport mode is vastly improved.

Our test car was fitted with adaptive suspension and steering systems, which are fitted as standard to M Sport models, but were optional on the Sport trim tested. In either mode, the steering is consistent and precise, although we would prefer a little more weight when pressing on. At lower speeds, the lightness makes for an effortless steer.

Whether an increase in torsional rigidity actually translates into improved handling on the road is hard to say – a back-to-back test will be necessary for that – but the 435i certainly turns and grips as well as the best mid-sized coupés. There’s very little understeer, and the ESP kills oversteer almost imperceptibly. 

The Sport+ setting provides an electronic limited-slip diff to allow a little more movement from the rear end.

Should I buy one?

Yes. The BMW 435i is an exceptionally able machine, offering huge performance coupled to thoroughly reasonable running costs. And a £40,795 price tag is all the more impressive given its performance credentials are only slightly short of the £54,980 E92 M3.

Perhaps BMW’s biggest failing isn’t so much with the 435i specifically, as it is an excellent car, but with the fragmentation of the 3-series range. It doesn’t feel different enough to warrant that all-new name. 

Nevertheless, in the 435i is a hugely appealing and entertain sports coupé, and it offers a sheen which rivals will need to work hard to beat.

Looks fantastic ... Except for the lower front bumper/fog light area, which looks like a child pulling a face; you half expect to see a tongue poking out ...

40MPG in a 300+BHP 6Cyl Petrol!  Stick that engine in the previous 3 Coupe please. That front end is horrendous. Looks nothing like the rest of the car. Ruins it for me, and if its anything like the 3 series it doesnt look much better in person from the front

19 July 2013

Not sure about the front end styling, looks like there's a bit missing,maybe it's just being used to the old stly?,the rear is a bit Conservative,doesn't really advertise what it can do,and, i 'll be surprised, going by reports i've read, that it will do 40mpg,28mpg is more like it.

That huge overbite on the front end makes it look like it was styled by Matt Groening. 

Here's my name again

I guess I got my hopes up too much, but if this review turns out to be close to the truth the driving experience sounds disappointing:

"In pure driving terms, it is every bit as engaging as the Audi A5coupé and Mercedes-Benz E-class, if not more so. The electro-mechanical steering is accurate, responsive and quite well weighted with eager self-centering traits up to moderate speeds. However, a reduction of assistance makes it artificially light, rather devoid of feel and lacking any true feedback at higher speeds."


That and the poor ride, bit of a let-down...  I'd got used to these things being comprehensively better than the fare served up by Audi and Merc.

Standard 17 inch wheels - that's a disgrace on a 435i. Just a way of making the headline price look better. Likewise having manual as std but supplying only autos to test. I wonder what other optional gadgets are enhancing the review but whcih will add 000's to the price. I bet just the wheels and auto will add at least £3K to the asking price

The Audi S5 might have its limitations but at least the standard spec includes the S tronic gearbox and 19 inch wheels, so you might actually only pay the £43K asking price.

I still don't know why BMW felt a name change was important, and why they're making such a big deal of it. It's clear for everyone to see that this is simply a coupe version of the 3-Series, so why try and differentiate the two or come up with some markeing clap trap about the need to make the 4-Series unique which will also enable them to expand the range as a separate model line up. The 3-Series GT is more unique yet retains the 3-Series moniker.

And if BMW's reason is that the 6-Series has its own badge, that's not really a valid argument because although based on a 5-Series, it is a unqiue model in the 'GT' class like the XK. It also has a unique interior and shares not one body panel with the saloon while it's looks and dimensions are disparate too to suggest that it is not a 5-Series coupe, but a proper and distinct model range in its own right.

It looked allright in a concept but this is just rubbish. They changed it and now its just strange sticking out to the sides. I know design is a matter of taste and maybe when I see it on the street it will be better but still its quite exagerrated. 3 series is way cooler and the coupe was supposed to be nicer (cause its goint to be more expensive for sure)

E92 was a special vehicle and design is fresh still today.

19 July 2013

The car pictured looks like an SE model to me. I think the front styling will look much better in M-Sport trim, as it does on the 3 series saloon.

Good to see Greg's been caning it. Did BMW notice that he'd smashed in the front bumper over a speed hump when he took it back??
