Horsepower Unleashed – Motivating the All-New Ford Mustang with Improved Power-to-Weight Ratios

• 5.0-liter V8 headlines all-new Ford Mustang lineup with 435 horsepower and 400 lb.- ft. of torque and improved power-to-weight ratio
• New 2.3-liter EcoBoost® brings turbocharging and direct injection to Mustang with 310 horsepower and 320 lb.-ft. of torque – 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 downshift rev- matching

DEARBORN, Mich., July 17, 2014 – The all-new 2015 Ford Mustang offers three great engines including a standard 300-horsepower V6, a brand-new 310-horsepower EcoBoost® or an upgraded 435-horsepower V8. Each powerplant 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.

The fewer the pounds a car carries for every unit of horsepower generated by the engine, the quicker and nimbler it feels, making power-to-weight ratio a key measure of performance. A recent study by Autoblog of cars currently available in the U.S. market puts Mustang at the top of the charts in power-to-weight ratio for all three price categories a customer can specify.

Mustang extends its lead further for 2015 with the EcoBoost-powered fastback now carrying fewer than 11.4 pounds per horsepower; Mustang GT has as few as 8.52 pounds per horsepower.

Less is more, EcoBoost comes to Mustang

The addition of a new 2.3-liter EcoBoost engine brings turbocharging to the Mustang powertrain lineup. 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 optimized to provide better breathing and higher output in Mustang. Producing 310 horsepower and 320 lb.- ft. of torque, the 2.3-liter EcoBoost engine fits the bill for a true Mustang powerplant – with the highest power density yet from a Ford engine.

"This EcoBoost engine delivers the healthy output Mustang drivers expect, regardless of the car's speed," said Scott Makowski, EcoBoost powertrain engineering manager. "It delivers where a Mustang driver expects it to – with a broad, flat torque curve and great driveability under any conditions."

The newest member of Ford's global EcoBoost engine family, the 2.3-liter 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-liter 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 maximizes 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 maneuvers.

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.

With a compact mill generating nearly 135 horsepower per liter and more than 139 lb.-ft. of torque per liter – powering a performance car whose drivers are more inclined to use it – ensuring engine durability was critical. Enhancements to the Mustang EcoBoost engine to withstand the added stresses include:

Forged-steel crankshaft
Piston-cooling jets
Steel piston ring carriers
Premium bearing materials
Upgraded valve seat materials
Forged-steel connecting rods
High-pressure die-cast aluminum cylinder block with ladder-frame bearing caps
Deep-sump, die-cast aluminum oil pan

The beating heart of a pony

No Ford Mustang engine lineup would be complete without a great V8 engine at its core. The 5.0-liter 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. 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 cutouts clear the new larger valves
Rebalanced forged crankshaft to support higher-rpm operation

These upgrades have boosted output of the V8 to 435 horsepower and 400 lb.-ft. 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 optimized 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 cupholders, 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 downshifts – now 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 optimized and operating temperature increased to reduce friction. The output shaft is now supported by a ball bearing that enables a top speed of 155 mph for Mustang GT.

With a choice of powertrains 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.

So the GT weighs 3706 lbs?

I thought this thing was going on a diet.

Irunelevens

It gained 87lbs because of the IRS. I'm ok with that tradeoff.

Isn't that about what a 4th gen weighs?

**** it.. This car is promising so let's find things to complain about it, too. Just like the hellcat.

So true!

How about we start with the with the 2.3L EcoBoost; WTF!
I don't know about you, but I couldn't get myself to ever buy a full sized muscle car with a 4 cylinder engine regardless of the turbo.
IMO, Ford really should have went with 3.5L EcoBoost® V6 as it's motor below the 5.0 V8 option; NOT the 2.3L EcoBoost .

I think they are trying to bring back the "SVO"

JD_AMG

Heaviest 4th gens were 3600lbs tops, maybe. Average was 3400-3500lbs, and if I remember right some of the stripped models were around 3300lbs.
3700lbs is what the GTO weighed.

JD_AMG

I totally agree with this, however Im betting they are trying to market to the "import crowd", mostly blind kids that think turbo 4s are "cool".

H8R

Sounds like good technology to me. Car doesn't look bad either.

Looks are subjective, so to each their own, but I like it. I also like what I see in that press release regarding the upgrades to the engine. This car will perform well.

Initial thought is by only bumping the HP in the V8 to 435, they leave the door wide open for GM to swoop in and take the HP crown by offering 450 hp in the 6th Gen. Regardless, this car will sell.

I like the car actually, but is anyone a little disappointed with the 5.0 hp rating? Maybe they underrated it, but with all the hype I honestly expected more than 15hp

Still looks like a 2 door fusion.

Not saying it is a bad look, but the Mustang and Camaro have had their own looks from the rest of their respective families, so I'm not keen on the blurring of that line.

The more I think about it, Ford did great with the new mustang: 3700lbs with IRS is very respectable. Its more hp than the current Camaro and its lighter.

The Camaro wont be here till 2016 officially so it gives time Ford to wipe out the competition and then bump up the hp numbers when the LT1 Camaro hits the streets. Plus the gt350 or gt500 hp numbers will make headlines to make plp forget about the new Camaro performance.

At first I hated the look of the Mustang, but the silver GT with the track pack/black wheels I saw in the lastest motoman video looks ******* nice. The interior looks top notch too. Id be ready to purchase that Mustang. The rear end is gorgeous...

99Bluz28

Yeah, but even the import crowd prefers a larger motor when it's available, and Ford already has the Focus and Fiesta ST turbo models geared towards the import crowd. Anyway it's already be done before with the SVO, and although it looked cool and somewhat futuristic I never met a mustang GT owner that was a fanatic of the SVO turbo 4 engine.

I do have to agree it's a good looking car, but the nose is UGLY, especially in a direct side view!

The Inline 4 will return much better mileage than the Ecoboost V6, and that is the real driver of the decision. Camaro will likely get the same treatment. I like this version way better than 2005-2009, they were just dreadful.
