Horse is transforming powertrain technology. What is the
vision driving this strategy?
At Horse, we believe the future of propulsion is not singular
but multiple. Our vision is to deliver next-generation hybrid and
thermal solutions adapted to the realities of different markets,
while ensuring efficiency, low emissions, and innovation. At
IAA Munich, we presented two examples that illustrate this
ambition: the Horse C15 Range Extender, an ultra-compact
1.5-liter modular engine just 27 centimeters in size, designed
for maximum efficiency in hybrid platforms; and our hydro-
gen-fueled internal combustion engine, which shows that
conventional technologies can be reinvented sustainably. Both
projects highlight our goal of anticipating mobility challenges
and positioning Horse as a global leader in innovation.
The Valladolid R&D center has grown rapidly. Which projects
best highlight its role?
The Valladolid center has become a true driver of innovation.
Over the past two years, we have evolved from a regional unit
into a strategic hub with global reach. Our projects include the
development of hybrid batteries across different voltage levels
(48V, HEV, PHEV), the optimization of compact powertrains,
and the adaptation of our technologies to meet diverse market
and regulatory requirements. What makes Valladolid unique
is our fully integrated approach: concept design, prototype
construction, bench testing, and track validation all take place
under one roof. This end-to-end process ensures agility, tech-
nical coherence, and faster time to market for our solutions
worldwide.
Spain now coordinates Horse’s global R&D. What are the
main challenges?
Taking on global coordination has been both exciting and
demanding. Our teams collaborate across Europe and Latin
America, while working closely with colleagues in Asia at Auro-
bay. The challenge lies in integrating not only different technol-
ogies but also different cultures and regulatory frameworks.
Maintaining speed in such a diverse environment requires
strong methods and tools. Which is why we have reinforced
our organization with agile methodologies, shared digital
simulation platforms, and a modular development strategy
that allows us to scale solutions quickly. Looking ahead, the
application of AI and advanced computing in mobility R&D will
be a game changer – almost a quantum leap – and will further
strengthen Spain’s role as the epicenter of our operations.
Horse owns the full hybrid powertrain system, from concept
to component. How does this enable innovation?
Full-system ownership gives us a decisive advantage. It
allows us to optimize the powertrain as a whole – from the
very first sketches of the engine concept to the calibration of
the software that controls it. This holistic approach enables
us to integrate electrification (48V, HEV, PHEV, REX), alterna-
tive fuels, and aftertreatment technologies from the outset,
rather than as add-ons later on. In the case of the H2 ICE, for
example, our ability to combine combustion development with
tailored emissions treatment has been essential to delivering a
robust hydrogen solution.
How has AVL supported Horse’s technology development?
AVL is a strategic partner with whom we share a long-term
technological vision. Their expertise in validation, modeling,
and advanced engineering tools has enabled us to accelerate
complex projects and ensure reliability at every stage. What
we particularly value is the complementarity: AVL contributes
world-class know-how, simulation and testing capabilities,
and large-scale integration experience that perfectly match
our in-house strengths. This partnership has proven vital in
transforming ideas into industrially viable solutions.
Validation is key to robust innovation. How has AVL’s exper-
tise accelerated development?
Validation is central to our strategy. Working with AVL, we have
been able to deploy high-precision simulation and advanced
testing that significantly shorten development times while
improving robustness. A good example is the creation of joint
virtual environments that reproduce the powertrain’s behavior
in the vehicle. These tools allow us to test and optimize earlier
in the cycle, reducing time to market and cutting prototype
costs, while maintaining high levels of confidence in system
performance.
What does the future hold for the Horse-AVL partnership?
The opening of AVL’s new testing facilities in 2026 coincides
perfectly with our roadmap for scaling next-generation
technologies. We are currently advancing hybrid systems that
are already benchmarks in the market, while expanding our
work in hydrogen engines and e-fuels. We also presented a
range extender concept at IAA Munich that attracted major
OEM attention. From Valladolid, we will continue to develop
technologies that address global mobility challenges. In this
journey, AVL will remain a decisive partner, ensuring that Horse
consolidates its role as a global leader in hybrid, thermal, and
alternative-fuel propulsion systems.
