5.0-litre V8 headlines all-new Ford Mustang line-up with 306kW and 530Nm* of torque and improved power-to-weight ratio
New 2.3-litre EcoBoost brings turbocharging and direct injection to Mustang with 233kW and 432Nm* best-ever power density from a Ford engine
Manual transmission provides smoother shifting than previous Mustangs; automatic transmission features steering wheel-mounted paddle shifters and down-shift rev-matching
MELBOURNE, 19 Jan, 2016 The all-new 2015 Ford Mustang offers customers the choice of two great engines including a brand-new 233 kW EcoBoost engine or an upgraded 306 kW V8.
Each power-plant is available with either a manual or automatic transmission that makes the pony car a great all-around performer no matter how the equipment is mixed and matched to suit any individual driving style.
Less is more, EcoBoost comes to Mustang
The addition of a new 2.3-litre EcoBoost engine brings turbocharging to the Mustang power-train line-up. This engine was designed specifically for Mustang, to meet the needs of drivers looking for outstanding performance and fuel efficiency.
The geometry of the EcoBoost intake manifold and turbocharger housing has been optimised to provide better breathing and higher output in Mustang. Producing 233 kW and 432 Nm of torque, the 2.3-litre EcoBoost engine fits the bill for a true Mustang power-plant with the highest power density yet from a Ford engine.
To put this into context, the last time Ford sold the Mustang in Australia in 2001 the car had a 4.6-litre quad-cam V8 that produced 240 kW of power and 430 Nm of torque. Fast-forward to today and customers will see that state-of-the-art EcoBoost technology is changing the way customers see performance as well as fuel efficiency.
The EcoBoost engine delivers the healthy output Mustang drivers expect, regardless of the cars speed. It delivers where a Mustang driver expects it to with a broad, flat torque curve and great driveability.
The newest member of Fords global EcoBoost engine family, the 2.3-litre continues to take advantage of state-of-the-art technologies including direct fuel injection, twin independent variable camshaft timing and turbocharging to produce big-engine power and torque with improved fuel efficiency.
The 2.3-litre EcoBoost is the first Ford engine to use a low-inertia twin-scroll turbocharger that provides quicker boost response while enabling lower emissions and improved efficiency.
The cylinder head features an integrated exhaust manifold that separates the inner and outer pairs of cylinders into each of the two inlet passages to the turbo. Keeping the exhaust pulses separated from the next cylinder in the firing order virtually eliminates mixing losses and maximises the pulse energy to the turbine wheel.
The result is similar performance to a more complex twin-turbocharger configuration, meaning quicker turbine spin-up and torque delivery when the driver needs it for passing manoeuvres.
The separated exhaust ports also enable the exhaust valves to stay open longer for reduced pumping losses that improve specific fuel consumption compared to a single-scroll turbocharger configuration.
Enhancements to the Mustang EcoBoost engine to withstand the added stresses include:
No Ford Mustang engine line-up would be complete without a great V8 engine at its core.
The 5.0-litre V8 powers into a new generation with a host of upgrades that help it breathe better, especially at higher engine speeds.
Many of these changes are derived from lessons learned in developing the special-edition 2012 Mustang Boss 302. Getting air into the cylinders and exhaust out is key to generating more power and torque from any engine without compromising driveability.
That has been the focus in the development of this V8, which features:
- Larger intake valves
- Larger exhaust valves
- Revised intake camshafts
- Revised exhaust camshafts
- Stiffer valve springs ensure valves close completely at high rpm
- New cylinder head casting revised ports provide straighter path to the valves for less restrictive intake and exhaust flow; combustion chamber modifications accommodate larger valves
- Sinter forged connecting rods are lighter and more durable for high-RPM operation
- Redesigned piston tops deeper cut-outs clear the new larger valves
- Rebalanced forged crankshaft to support higher-RPM operation
These upgrades have boosted output of the V8 to 306kW and 530 Nm of torque.
A new intake manifold includes charge motion control valves to partially close off port flow at lower engine speeds. This increases the air charge tumble and swirl for improved air-fuel mixing, resulting in better fuel economy, improved idle stability and lower emissions.
The variable camshaft timing on the intake side now has a greater range of adjustment available thanks to mid-lock phasers. This enables better optimised control of the valve timing over a broader range of engine speeds and loads for improved fuel economy and emissions.
Shifting gears
More than most drivers, Mustang owners like to take control and shift for themselves. Whether they select a fully manual gearbox or the updated automatic transmission, the experience will be better than in any previous pony.
The manual has a new shift linkage design for easier engagement and improved precision. The shift lever is now positioned closer to the driver and away from the cup holders, creating a clear path for shifting.
Mustang blends outstanding all-around performance and everyday usability. Drivers who prefer to let the car handle the shifting during their daily work run, but who still want to take control when the roads get twisty, will appreciate the new steering wheel-mounted shift paddles with rev-matching down shifts standard with the SelectShift six-speed automatic transmission.
The automatic also features a redesigned case with cast-in ribs that help make it stiffer and reduce weight. Internally, clutches are optimised and operating temperature increased to reduce friction.
With a choice of power-trains to suit driving preferences and lifestyles, the new Mustang has cutting-edge technology under the hood to match its modern design. Yet regardless of engine choice, the car remains quintessentially Mustang.
