Powering Porsche 911 GTS & Turbo S: The Cell Behind the T-Hybrid

Our first use-case white paper is here — a close look at how the V4Smart V21700 UHP-26 booster cell helps bring the new Porsche 911 Carrera GTS and Turbo S to life.

The new 911 Carrera GTS and Turbo S mark the first hybridization of a performance icon — and V4Smart is proud to be the cell partner behind it. Our new white paper takes you inside Porsche’s T-Hybrid powertrain and shows why high-power cell design — not large stored energy — is the key to making it work.

At the heart of the T-Hybrid system sits the V4Smart V21700 UHP-26 booster cell: built in Germany, IATF 16949-certified, and engineered to deliver intense bursts of power, absorb rapid energy recovery, and stay thermally stable — all in a compact, lightweight package that fits seamlessly into the 911’s DNA.

What’s inside the white paper

• How the T-Hybrid powertrain works
  The electric turbochargers (eTurbos) and the PDK e-motor, and the role each plays
• Why the 911’s hybridization is so demanding
  High pulse power, rapid energy intake, and tight thermal control in a small, lightweight package
• The UHP-26 booster cell explained
  >8,400 W/L power density, pulse power up to 400 W, continuous 100 A, and fast charging to 80% in under 6 minutes
• Durability that lasts
  >2,500 cycles at 100% depth of discharge with over 80% state of health
• Why the approach scales
  From the first-ever hybrid Carrera GTS to the most powerful 911 to date, the Turbo S
• Where it goes next
  Beyond automotive, into fuel-cell trucks, aerospace, and security applications
