Development Mule
Kalana
Carbon fibre prototype. Three circuit lap records. Built from scratch in Estonia with no factory backing.
Overview
What Kalana Is
Oldbac’s first operational chassis. Designed from scratch in Estonia and built to validate aerodynamic theory against real track data. Every component exists to generate information, not to impress.
On its competitive debut it broke the Porsche Ring lap record. Across individual events it has set three circuit lap records, running without factory support. The data acquired directly informs the design of Tahkuna, the next-generation Pikes Peak prototype.

Engineering
Aerodynamic Efficiency
1,470 kg of downforce at 250 km/h. The aero package was designed computationally, then validated at the Pininfarina wind tunnel in Torino. CFD and physical data now correlate within margins useful for Pikes Peak altitude modelling.
Low mass
910 kg wet, no fuel or driver. Carbon fibre monocoque primary structure. Every component selected or manufactured to minimise mass.
Packaging
Judd DB 3.4L V8, double wishbone push rod suspension front and rear. Layout prioritises centre-of-gravity placement and clean rear diffuser airflow.
Validated on track
Three lap records across individual events in 2023 and 2024. Theoretical models tested against physical telemetry. Data directly shapes the Tahkuna programme.

Frequently Asked
What stage is Kalana currently in?
Kalana is a fully operational prototype in active use. It is currently running a testing programme to generate aerodynamic and mechanical data for the Tahkuna project.
Is the car already running?
Yes. Kalana has competed at individual events and holds three circuit lap records.
Is it road legal?
No. Kalana is a track-only single-seat prototype designed exclusively for development and competition.
Are customer cars planned?
Not for Kalana. It is a development vehicle. The Tahkuna programme includes a limited customer car allocation.
Are specifications final?
Current specifications reflect the prototype as tested. Some parameters may change as the development programme continues.
Can sponsors or partners get involved?
Yes. Oldbac is open to technical partnerships and sponsorship discussions. Visit the sponsorship enquiry page for details.
Where is it developed and built?
Kalana was designed in Estonia. Manufacturing involved both in-house work and specialist partners. Aerodynamic validation was conducted at the Pininfarina wind tunnel in Torino, Italy.
