If you believe that there’s no substitute for horsepower, then you’ll be rejoicing in 2012 as Ford updates the iconic Mustang muscle car line-up. The new Mustang  will be ready to go in spring but the real power will be later in the year with the return of the Boss 302 and the Shelby GT500, expected to be the most powerful production V8 available.

The 2013 Ford Mustang has a new exterior design with a bigger front grille, re-styled hood and signature LED lighting to give the car a high-tech look. The automatic gearbox now has “SelectShift Automatic” transmission as standard, for drivers who want greater control over the growling 5 liter V6 engine.

But it’s not just high-tech on the outside, as in an industry-first, the Mustang comes with a 4.2″ LCD car information system with TrackApps; a suite of apps that monitor the car’s performance, including acceleration, cornering-g and braking.

The LCD screen is navigated by a five-way control button to access information relating to fuel economy and vehicle performance. The TrackApps give performance metrics for g-forces, acceleration times for quarter mile and 0-60, and braking times. It also indicates automatic and countdown starts.

“The new Mustang is the perfect example of continuing to build on excellence. It takes the greatness of the 5.0-liter and V6 and pushes the refinement to the next level,” said Dave Pericak, Mustang chief engineer. “The car has been spot-on functionally and now we’re adding more features and technology to further improve the driver’s experience.”

The Boss is back, paying homage to a 70’s legend, the Ford Boss 302 Mustang and the car that won the 1970 Trans-Am Championship, driven by Parnelli Jones. Building on this heritage, the new Boss 302 and Boss Laguna Seca will be available in School Bus Yellow, the same colour as the championship-winning car.

The 2013 Boss 302 comes with 444 HP delivered to the rear wheels via a carbon fiber limited-slip differential – there’s over 380 lb-ft torque available. The orginal Boss 302 had a little under 300 HP under the right foot and in its day, the 302 was the fastest car to lap Ford’s test track.

Compared with 1970 model, the new Boss is totally high-tech, with Ford SYNC as standard. SYNC is a voice-activated in-car connectivity system, with features including
– hands-free control of mobile phones and USB-connected digital music players.
– 911-Assist that automatically calls the emergency services in the event of an accident.
– Vehicle Health Report, an on-demand diagnostic and maintenance system.

The real petrolheads will have to wait until later in 2012 before they can get their hands on the new 2013 Ford Shelby GT500 Mustang, which will lay claim to be the most power production V8 in the world, pumping out 650 HP from the 5.8 liter supercharged V8 engine. 600 lb-ft of torque will be on-tap and a 4 second 0-60 time is expected. Whoa!

While there may be no substitute for horsepower, a great deal of technology has gone into making sure that the Shelby GT500 goes round the corners quickly as well. Ford’s Special Vehicle Team (SVT) has worked with world leaders in car design to ensure that the Shelby GT500 is fast. SVT-designed Bilstein electronic adjustable dampers can be adjusted from within the car. A Torsen limited-slip differential ensures that as much power as possible gets through the rubber to the road. Brembo braking system aggressively deccelerates the 3,850 lb car with six piston calipers and fade-resistance rotors.

“SVT keeps the Shelby GT500 on the cutting edge of technology and takes muscle car performance to new heights,” said Jost Capito, director of Global Performance Vehicles and Motorsport Business Development. “We encapsulated every aspect of performance in this car – whether it’s 0-60, top speed, racetrack or quarter-mile times. Beyond that, the daily driver also will find this car perfectly fits his or her needs.”

Nearly every part of the powertrain has been improved for producing the additional horsepower, including a new supercharger, new cross-drilled block and heads, updated camshaft profiles, a new carbon fiber driveshaft and upgraded clutch, transmission and axle. Putting down 650 HP isn’t easy – it’s not as easy as simply putting in a bigger engine.

The 200 mph top speed needed an enhanced aero-package to keep the wheels on the road at high speed and every aspect of the air flow over the vehicle was analysed and harnessed to improve cooling, maximise downforce and minimise drag. As a result, there’s over 33% more downforce at 160 mph compared with the previous model.

The Shelby GT500 is also equipped with an SVT-designed launch control system that allows the GT500’s pilot to adjust the start depending on tire temperature, street surface and other conditions. The launch system is smart enough to interface with both the engine managment system and traction contol to optimise the getaway.

For those drivers more confident of their skills or wanting to learn greater control, the electronic systems can be programmed for a range of situations. The Intermediate mode allows drivers to push the car without completely disabling the safety systems, allowing more aggressive driving before traction control and electronic stability control kick in. For real racing, both the systems can be completely disabled requiring maximum driver skill.

“We took a completely different approach with this car so drivers can choose their settings instead of a computer making the selection,” said Jamal Hameedi, SVT chief engineer. “Nearly every system the driver interacts with can be tailored to his or her situation including the Bilstein electronic adjustable suspension, launch control, AdvanceTrac and steering assist levels.”

Whether it’s the Mustang, the Boss 302 or the Shelby GT500, there is a ton of technology and gadgetry in all of these vehicles. Much of this technology would only have been available to race teams just a few years ago and here it is now in street-legal car. Visit your local Ford dealer for a test and once you’ve stopped fiddling with the gadgets, you can go out for a drive.
