BMW 3 Series (2005- To Date)
Introduction
History of the 3 Series
After all, this 3-Series was forced to redefine its place in BMW's range. For the first time in 29 years, it was no longer the entry level BMW model, and the range was developed in a way that 1-Series buyers could migrate to a Three on the way to bigger BMWs. At least that's what the suits in Munich were hoping. Bigger in every dimension to its predecessor, the 3-Series appeared in UK dealerships in April 2005 in saloon guise, the existing E46 generation coupes, Tourings and convertibles being sold alongside.
Touring models of this car appeared in September 2005 with the Coupes arriving in September 2006, but along the way, the 3 Series range has been fleshed out with the 330i (July 2005), the 330d (November 2005), the 318i (January 2006), the limited run 320Si (June 2006) and the 335i, 325d and 335d (September 2006).
The Autumn of 2007 BMW included its EfficientDynamics package across the 3-Series range with dramatic effects. The technology uses Brake Energy Regeneration and Auto Stop-Start amongst other features to dramatically cut emissions and enhance fuel economy. The headline grabbing model was the 318d which became capable of over 60mpg on the combined cycle and 123g/km emissions. The V8-powered M3 saloon arrived early in 2008.
Why should I buy a 3 Series?
For a start, it's beautiful in its own right. Contemporary BMW design has been a strangely hit and miss affair but the bullseye was firmly hit in this instance. Taut, sleek, muscular and boasting not a single shared body panel with the 3 Series saloon, the latest Coupe earned whole legions of buyers before they ever clapped eyes on one in the metal. The silhouette is lower and more elongated, giving it an elegance that's singularly lacking in the buttoned-down saloon.
The kidney grilles at the front were restyled to give a simpler, cleaner look while the headlamps have a more piercing stare. Move round to the rear and you'll pick out the broad tail light clusters that incorporate horizontal LED rods. On the way, you'll spot the sculpted flanks and should you tap the front wings, you'll find that instead of the high-pitched ring of steel, you'll hear the duller thud of plastic. In a bid to cleave weight from the 3 Series Coupe, BMW used plastic as well as the more traditional method of 'tailored blanks' - panels that are thick where structural rigidity is needed and thin where it's not.
How much could I expect to pay?
The six-cylinder 325i is worth a look and these open in SE trim at £16,100. Opt for a glitzy M Sport model and you'll need to find at least £19,500, still quite a sum. 325i Tourings open at £18,000. The 330 is a popular pick and these kick off at £18,000 for an SE saloon on the 54 plate. The best all-rounder in the line-up remains the 320d and the value-packed ES model starts at just under £15,300.
What should I look out for?
Be suspicious of cars that have had many owners in a short time (this could be a sign of ongoing problems). If you really want peace of mind, buy from a BMW dealer - but be prepared to pay the premium.
Are parts expensive?
What is a 3 Series like to drive?
The 320i is an engine based on the architecture of the 318i motor in the previous generation 3-Series. With improvements to the induction and VANOS systems, this engine jumps to a round 150bhp. Capable of covering the sprint to 60mph in 8.8 seconds and able to hit 137mph, the 320i can also manage to eke 38.2 miles from a gallon of unleaded. Also highly capable is the 320d, BMW's biggest seller in the old E46 generation car. In this instance, power leaps from 150 to 163bhp. This diesel will take a fraction over eight seconds to get to 60mph and posts a top speed of 140mph. The 49.6mpg fuel economy figure is a real standout.
The 330i and 330d are two very successful aspirant models. The petrol features a 3.0-litre Valvetronic engine with technology that does away with conventional throttle butterflies in favour of a complex electrically-powered valve lifting system. Constructed from an aluminium and magnesium composite, this engine sits tucked well back in the car's cavernous engine bay and gives the car excellent weight distribution. Less weight also equates to better performance, more agile handling and lower fuel consumption and emissions.
This engine punches well above its modest weight, knocking out 258bhp at 6,600rpm. On the road this translates into a surprising amount of heft. The sprint to 60mph from rest will disappear in just 6.3 seconds and will run into BMW's self-imposed electronic limiter at 155mph with plenty to spare. Despite this, the fuel economy figures are better than the old 231bhp 330i at 33.5mpg. The Valvetronic engine complies with the latest Euro IV emissions regulations and features an electric water pump to cool the engine block for increased efficiency. If you can't quite stretch to starting prices for this variant, a 325i petrol model is also available. Then there's the improved 330d, which is nearly as quick as the 330i with a 6.7s 0-60mph time and far more economical with 43.5mpg. A full 500Nm of torque makes this model an amazingly muscular choice.
The 335i engine also merits special mention. Despite the 335i badge, the engine fitted up front in this car is 'only' a 3.0-litre, much akin to that found in the 330i. Whereas that car develops 272bhp, the 'blown' 335i is good for 302bhp. BMW could have no doubt turned the wick up on the turbochargers to offer way more power but the key to the 335i is in creating a turbocharged model that offers none of the drawbacks of turbo cars. In real terms, that means a sprint to 60mph in 5.2 seconds and a top speed limited to 155mph. That's not far off the old M3 and in terms of torque to weight, the 335i trounces the old hotrod, the M3 offering 171lb/ft per tonne compared to the turbo car's 184lb/ft per tonne.
