Is Goldman Sachs right that 7 megatrends will dominate the global auto industry's future?

This week, Goldman Sachs's research team published a massive note on the future of the global auto industry.

Really, it was a note on the future of human mobility. But are these trends inevitable? Will they really transform the way we get around?

Let's break it down.

Goldman's analysts, led by Kota Yuzawa and Patrick Archambault, highlighted seven "megatrends." I've annotated them, but here they are in total:

1. Endless powertrain advancement
2. Autos on a severe diet
3. Autonomous driving on horizon
4. Power shift to mega suppliers
5. New entrants afoot
6. Connected cars and shared mobility
7. Shift to emerging markets

And now the breakdown:

1. Endless powertrain advancement: Power train electrification is essential to meeting fuel economy regulations, and we expect the shift to hybrids (HVs), electric vehicles (EVs), and fuel cell vehicles (FCVs) to continue. Improvements to the internal combustion engine (ICE) also cannot be ignored. We expect gasoline/diesel engine vehicles will still make up 75% of global vehicle sales in 2025. Better engine performance is essential to raising the fuel efficiency of HVs and plug-in hybrids (PHVs). We expect a wait-and-see stance on FCVs until 2020.

We can forget about hybrids, which are well-established in the market right now and aren't going anywhere. They may plateau in terms of growth, however. The good old gas-burning engine is at this point a technology that's close to being perfected. Understandable, as car makers have been improving it for a century.

There are potential technological breakthroughs on the horizon, however, which would radically improve fuel economy. Like, hundreds of miles per gallon, using ordinary gas. If this happens, the picture for alternative propulsion tech changes radically, because gas is still the most economical and efficient way to power vehicles. This is the biggest threat to Goldman's 2025 outlook, although the analysts acknowledge it. The economics of electric cars and to a degree hydrogen collapse in the face of ultra-high-MPG gas/diesel vehicles, which could make up 100% of the global 2025 fleet.

2. Autos on a severe diet: A 50 kg drop in vehicle weight cuts CO2 emission volume by 1g per km. Despite efforts by vehicle makers, vehicle weight is trending up. The amount of reinforcement materials needed to meet collision safety standards is rising. For the next 10 years, we expect greater use of aluminum and high-tensile steel to be the main weight reduction measures. Carbon fiber reinforced plastic (CFRP) could be used in the future. According to the GS global steel research team, global steelmakers had EBIT of around US$25 bn from carbon steel in 2014 (we estimate auto-use steel accounted for around 20%-30%).

In the industry, this trend is known as "lightweighting." It's here to stay and scheduled to be a driving force for innovation over the next two decades. Regardless of what happens with the overall design and safety engineering of vehicles, which globally are getting larger as emerging markets take to trucks and SUVs, lighter materials are going to become more prevalent. However, initially we may see this primarily in the developed world, where customers can afford a certain premium for aluminum and composites. In developing markets, steel should stick around.

3. Autonomous driving on horizon: Google wants to realize Level 4 vehicle automation or full self-driving by 2017. Most automakers are focusing on Level 3. There are many hurdles to be overcome, including the Vienna Convention and compensation rules in the event of accidents. We believe preventive safety technologies will become standard before 2020 and Level 4 automation will be slower to take hold because of the numerous unknowns over liability and regulations. Preventive safety success will depend on how reasonably devices can be priced.

This one is spot-on. In fact, automakers are getting so good at semi-autonomous driving features, such as lane-change warning and adaptive cruise control, that we may see a sort of convergence and rapid improvement of everything that's already out there, leading to "Level 3.5" automation that, while not as impressive as Google-Car Level 4, will be "good enough."

Google has started at the finish line - a fully autonomous car that's highly self-aware of its location due to complicated, detailed maps integrated with sophisticated sensors and radars - and is working it way back to the race. Meanwhile, traditional automakers and new arrivals, like Tesla, are taking an additive approach, steadily improving the self-driving stuff that's already legal. They can apply these technologies in the real world and prepare for a big leap.

Google, by contrast, has to get everything right with its Utopian vision in order to pass regulatory muster. That said, a true Level 4 car would be extremely cheap, given that it wouldn't need much in the way of safety technology and could thus be very lightweight. So hidden in Goldman's prediction is a potentially dramatic reduction in the cost of vehicular mobility.

4. Power shift to mega suppliers: We estimate that meeting CO2 emission volume regulations will cost automakers US$2,500 per vehicle or US$25bn in total (global automakers generated EBIT of around US$120bn in 2014). This represents a business opportunity for component makers that improve the environmental credentials of vehicles. We expect the presence of mega suppliers to expand as more alliances are formed to reduce upfront cost burdens.

Goldman is narrowcasting here by focusing on the CO2 front, but the overall assessment is prescient. The global auto industry currently runs on a "just in time" lean-manufacturing model, so assuring an abundant and ready supply of parts is critical. This should drive plenty of future consolidation and M&A activity in the supply chain.

5. New entrants afoot: The appearance of autonomous driving and EVs is removing auto business entry barriers. Technology companies, including Google and Apple, are showing interest in the auto business. However, outsiders still face many difficult business hurdles, including production system, collision safety, and dealer network issues.

Nope. There are really three things going on when it comes to "new" car companies. First, Tesla is trying to validate a high-end electric vehicle model. But the vast majority of the auto industry is and will continue producing gas-powered cars. Second, Google is pioneering a entirely new model of mobility: the Google Car is designed to be an autonomous, self-aware, networked node in a mobility matrix. It points strongly toward a bet on de-ownership of personal transportation. Third, Apple is likely aiming to improve the user-interface of the automobile; Apple typically takes existing technology and Apple-izes it. This is largely a design problem, but Apple could be building some type of actual vehicle to use as a test platform.

So, actually, we only have one meaningful new entrant, Tesla. Obviously, other newish entrants may emerge - a big question is whether Chinese automakers will ever see a need to export, given the massive potential size of their domestic market. But non-traditional disruptors in the industry have not, and really never, fared well.

6. Connected cars and shared mobility: The use of vehicle position information and running data is likely to increase car share. Vehicle utilization is less than 5% and ownership costs are high. In Shanghai, for example, it costs US$12,000 to acquire a license plate. Connected cars could lead to changes in business models adopted by insurers (which rely on auto insurance for about 30% of revenues).

Nope. Car sharing works up to a point, in highly urbanized environments where ownership doesn't make financial sense. Car sharing also works for people who are new to the labor markets and low down the income ladder. But for most of the developed world and increasingly much of the developing world, convenience trumps sharing.

The great thing about owning a car is that you can jump into it and go someplace on a moment's notice, no tech required. Ultra-cheap cars make the ownership case even more appealing. Additionally, the entire auto industry is build on a credit model - car makers don't sell cars, they sell car loans - and de-ownership would undermine an important source of capital for a capital-intensive business.

7. Shift to emerging markets: Motorization in emerging markets continues unabated. By 2025, we expect China to have 35 mn vehicles and India 7.4 mn vehicles. Automakers must offer affordable cars that will sell and be profitable, but we see scope for a shift to larger and higher-end vehicles. Amid increasing concern about CO2 emissions, the ability to offer affordable fuel economy technologies will be a major focal point even in various emerging markets.

A bit of a wildcard. China is set to be huge market, but its unclear whether it will be an efficient and competitive market. So far, it's Western automakers that have benefitted most from Chinese motorization, through joint ventures with Chinese car companies. A looming problem for the Chinese market is an excessive number of manufacturers competing for market share in a market that's centrally managed.

Contrast this with the US market, which is the best in the world right now, even though it will top out at half the size of the Chinese market by 2025 (17-18 million new cars sold annually, versus 35 million in China).

When it's operating correctly (i.e., not in a depression), the US market is well-oiled money-generating machine and a powerful engine for innovation, due to the shared stake that the government and citizens have in a healthy environment. Transparent credit flows, a relatively coherent method to execute recalls, and an abundance of established marketing channels as well as a robust automotive media also mean that it's easy, if not inexpensive, for automakers to connect with customers and sell the vehicles.

Additionally, an Indian market of 7.5 million is not all that great. Mobility in that country isn't shifting as decisively toward traditional cars, trucks, and SUVs as it is in China. Scooters, motorcycles, and mopeds remain popular. Plus, unlike in China where the luxury market is making a greater contribution, India is developing a reputation for providing basic mobility at very lower prices. Pursue that model, and you have sell A LOT of cars to make real money (for an historical example, see Volkswagen and the original Beetle).

So the bottom line is that Goldman's analysts have nailed it with three out of seven megatrends. The other four, however, are up for considerable debate.
