1 Diesel controversy Temporary shock or paradigm shift in powertrain? Impact of the diesel controversy on OEMs and suppliers Frankfurt, October 2015

2 Executive summary > European OEMs have utilized the fuel-efficient diesel powertrain as a key lever to reduce corporate fleet CO 2 emissions, especially in the EU due to /21 CO 2 vehicle emission targets. These targets are basically impossible to reach without diesel > We therefore expect diesel to remain a key pillar in OEMs' powertrain strategies, especially in Europe > The current debate about diesel will, however, further drive innovations in combustion 1) and after-treatment of diesel due to increasing regulatory requirements and standards, and will enforce test cycle implementation aiming to reflect Real Driving Emissions (RDE) > In order to fulfill RDE regulations, diesel will become cleaner (with emission levels similar to gasoline engines), but also more expensive > The resulting cost increase will accelerate the substitution process from diesel to smaller gasoline engines, especially in lower vehicle segments. Diesel will still remain dominant in the upper vehicle segments but total diesel share in Europe will decline in the coming years > OEMs therefore have to further accelerate alternative powertrain solutions. Suppliers have the opportunity to implement innovative solutions for the further control of diesel RDE, and should also step up their preparations for alternative powertrains 1) Such as homogeneous combustion and HCCI Source: Roland Berger 2

7 2 Toxic exhaust gas emissions As of today, the road transport sector is the largest source of NO x emissions in Europe Diesel is a major contributor NO x emissions by sector in EU-28, 2013 [%] 39.4% 8.2 m tons 21,0% 15,1% 12,2% Approx. 10% diesel passenger car contribution 1) 6,8% 2,8% 2,6% 0,1% Road transport Energy production & distribution Commercial, institutional & households Energy use in industry Non-road transport Agriculture Industrial processes & product use Waste 1) In Germany, as of 2012 Source: EEA; Bosch; Roland Berger 7

10 The 2025 outlook for diesel Decrease of diesel share in nearly all major automotive markets is expected 2025 worldwide outlook and drivers for the use of diesel in passenger cars > Customer interest in diesel in the US market will decline due to the recent controversy; diesel fuel price remains higher than gasoline > Main local car makers will focus on efficient gasoline engines and electrification > Diesel will only be offered in some niche market segments > European OEMs will still focus on diesel technology due to existing investments and CO 2 emission targets > Diesel powertrain is getting more expensive, partly due to implementation of RDE cycles with Euro 6c > Diesel will lose market share (esp. in smaller vehicle segments) > Chinese government is heavily promoting the development of battery electric vehicles (BEV) > Diesel engines will not play any role in China for passenger cars > Diesel engines are only relevant for trucks > Ban of diesel engine passenger cars in place > Fierce competition with ethanol/flex fuel (local production) > No uptake of diesel engines in passenger cars expected > Diesel fuel has a price advantage even without subsidies > Sales of diesel-fuelled cars expected to keep on rising > Strong focus of Japanese OEMs in alternative powertrain technologies (i.e. hybrid and electric vehicles) > Government subsidies for alternative powertrains > No major share of diesel engines in passenger cars expected Source: Diesel Technology Forum; press research; Roland Berger 10

11 Three scenarios on future of diesel possible in Europe 2030 "Most likely" is decrease of diesel with shift toward upper car segments Diesel scenarios in Europe/forecast new car diesel shares in EU-28 until ) "Diesel extinction" "Focused shift" "Diesel constant" Diesel engines to be fully replaced by gasoline and alternative powertrains Diesel engines decreasing, but remain the dominant powertrain in upper vehicle segments No changes regarding diesel as powertrain solution Diesel (incl. MH diesel) 53% 20% 10% 53% 48% 41% 53% 53% 53% Customers > Do not trust diesel technology as a "clean" solution any more > Still trust diesel technology as "clean" > TCO will be a strong buying criteria > Still trust diesel technology as "clean" > Diesel is "technology of choice" Politicians > Scrap actual tax incentives for diesel fuel > Strong support of alternative powertrains > Change regulations against diesel, e.g. ban it from the roads > Accept importance of diesel technology for CO 2 reduction in general > Increase regulation on Real Driving Emissions > Tax changes in some EU member states > Support the diesel engine without any restrictions Diesel technology > Does not meet new regulation targets > Diesel engine becomes more expensive due to additional after-treatment technologies > No additional technology needed Conclusion 1) In % of new car sales > Diesel will completely lose all importance by 2030 > OEMs have to shift their powertrain strategy to alternative solutions > Diesel engine will lose market share constantly, esp. in lower car segments > Diesel will still play a major role in upper vehicle segments RB most-likely scenario > Diesel will stay at the same level as today in terms of volume > No change in vehicle segments Source: EEA; Roland Berger 11

12 Diesel powertrain still expected to hold dominant position in upper passenger car segments despite decline in diesel share by 2030 "Focused shift": New car diesel forecast by segment in EU-28 until ) A Mini cars e.g. Fiat Panda 98% 100% 100% D Large cars e.g. VW Passat 16% 21% 31% 84% 79% 69% 2% B Small cars 64% 67% 74% E Executive cars 12% 20% 30% e.g. Peugeot 208 e.g. MB E-class 88% 80% 70% 36% 33% 26% C Medium cars 36% 40% 45% F Luxury cars 50% 56% 63% e.g. Citroen C4 64% 60% 55% e.g. BMW 7 series 50% 44% 37% Other powertrains 1) In % of new car sales Diesel (incl.

13 Diesel essential for CO 2 reduction by OEMs but higher technology demand to meet regulations Potential benefits for supplier industry "Focused shift": OEM and supplier implications OEMs Accept and close the gap between cycle and Real Driving Emissions of diesel engines Develop and implement (after-treatment) solutions in order to reduce RDE Adapt powertrain strategy by shifting the diesel focus from lower to upper car segments Accelerate implementation of alternative powertrain solutions (electrification) to meet CO 2 regulations Successfully convince car buyers and policymakers of "The New Clean Diesel" Innovative solutions for more efficient and clean diesel technologies needed Innovative solutions for more efficient gasoline technologies needed Suppliers Higher demand for alternative powertrain solutions increases demand for cost-intensive BEV/PHEV cars Higher demand for after-treatment solutions for diesel engines to meet RDE regulations Shift from diesel to gasoline engines in car segments changes the technology Long-term volume reduction through increasing demand for BEV cars Powertrain suppliers Exhaust syst. suppliers Source: Roland Berger 13
