Driven: BBR Mazda 3 MPS 320
Is 320hp too hot for a Mazda hatch to handle?
The turbocharged five-door has always existed on the fringes of the hot hatch market, but its trump card is the brawny 2.3-litre, direct-injection four pot. In standard form it produces 256bhp, but with an extra 300cc over the majority of the competition, and DFI, the potential is clearly there for more power.
The power of three
BBR offers the conversion in three stages. The first level simply consists of a remap, offering more peak power and torque, improved mid-range pull and, it's claimed, better cruising fuel consumption (as the engine runs leaner). For your £549 you get 290bhp and 330lb ft, which should be enough to grab the attention of any Focus RS driver.
The second-stage conversion features a high-flow fuel pump, replacement air filter, stronger turbo inlet hoses capable of withstanding more pressure, and a new exhaust down pipe, pre-cat and cat - as well as the remap. Thus configured, the MPS generates 320bhp at 6,580rpm and 370lb ft at 3,800rpm, according to BBR's figures. Nearly all of that torque is available from as low as 3,100rpm.
Far more serious modifications take place if you move to stage three. The standard top-mount intercooler is replaced with a front-mounted item, and you can choose to either have BBR rebuild the standard turbo with upgraded components, or if you're looking to go beyond 350bhp, they'll fit a Garret hybrid GT28, which sacrifices some lower-down response for 400bhp.
Quick...
There's a louder drone from the exhaust (although not an uncomfortable one, and it subsides under partial load) and an unusual sound from the turbo, a bit like someone turning a gas hob on.
Nevertheless, the bumpy, scarred lanes around Silverstone expose just how hard the car has to work to contain 370lb ft, despite the standard LSD. Admittedly, the cold, greasy surface of today doesn't help matters, but the torque steer requires a firm grip on the wheel.
Classy chassis?
So the 3 MPS is still not without its flaws, but it's hard to argue with the performance per pound on offer here.
