ST has unveiled a new performance package for the Audi S5 Sportback.

Designed to give the engine a healthy kick in the pants, the package consists of a revised ECU, a sport air filter, and a stainless steel exhaust system. Thanks to these modifications, the supercharged 3.0-liter V6 produces 375 hp (280 kW / 380 PS) and 495 Nm (365 lb-ft) of torque - increase of 42 hp (31 kW / 43 PS) and 55 Nm (41 lb-ft). While the company declined to release performance specifications, they stated the V-Max limiter is also removed as part of the conversion.

On the styling front, Senner decided to play it safe and not equipped the S5 with a body kit. Instead, they offer lowering springs (which reduce ride height 35-40mm) and 20-inch T1S Work VARA Diamond alloy wheels. Inside, the only change is the addition of carbon fiber trim around the instrument cluster.

Aznom and Romeo Ferraris have teamed up to create a modified Land Rover Defender.

Despite looking rather conservative, Aznom equipped the SUV with carbon fiber bumpers, a two-tone matte paint job, red accents, and black wheels with Kumho Road Venture tires. Inside, the cabin boasts alcantara upholstery, a carbon fiber steering wheel, Sparco sport seats, and carbon fiber trim.

Under the hood, Romeo Ferraris tweaked the 2.4-liter turbodiesel 4-cylinder engine to produce 152 hp (113 kW / 154 PS) - an increase of 30 hp (22 kW / 30 PS). While no performance data was released, the upgrade should help to move the Defender with a little extra oomph.

British tuning firm Oakley Design has just released a new package of upgrades for the Ferrari 458 Italia. Limited to a small series of 5 individually-numbered units, the tuned vehicle sees aerodynamic changes, a few cosmetic changes, and a remapped engine computer.

The ECU may be the most minor of otherwise significant alterations.Power is boosted by 10% from 570 PS (419 kW / 562 bhp) to 627 PS (461 kW / 618 bhp), while torque is bumped up 5% from 540 Nm to 567 Nm.

When combined with the other modifications, the engine computer's upgrade is a robust revision.  A larger carbon-fibre air intake box, larger ram air feeds and larger diameter white silicon pipes with Oakley Design logos connecting the air boxes to the intake all contribute to improved throttle response and increased output as described by the ECU upgrade.

Aerodynamics are improved with a front spoiler that "adds 45kg of downforce" to the front end at speeds of 150 mph (241 km/h).  25kg of downforce is added at the back, and at the same speed, thanks to the added rear spoiler with a Gurney flap.  At the same time, airflow is improved with the central radiator vent, radiator exhausts next to the headlights, stylized side sills, and new rear and underbody diffuser.

New 9.0Jx20-inch front, 11.0Jx20-inch rear OZ Racing wheels with Pirelli Trofeo tires have also been installed.  Combined with a 65kg weight reduction thanks to the carbon fiber mods, which includes a new roof panel, the car is capable of faster sprints and better top speed.

The Oakley Design Ferrari 458 Italia reaches 100 km/h in 3.0 seconds, a 0.4-second improvement.The car tops out higher than 330 km/h.  Those wanting the Oakley Design tuning kit, but not able to get one of the 5 limited edition models, can purchase parts individually from the firm.
