Roadster ClubTesla Roadster 2017 vs 2026:
which specs changed?
The 1.9-second acceleration claim and 620-mile range belong to the older concept. The 2026 reveal introduces a different design and three distinct versions.
Are the old Roadster specifications still current?
Historical concept figures should remain attached to their original date. The current version descriptions and the unveiling demo are separate evidence; unknown current figures stay unknown.

What actually changed?
One old concept is now several descriptions
The 2026 product page separates road-focused Performance, rear-thruster Thrust and flight-system Rocket. The old concept is not a fourth orderable trim in our comparison tool.
Acceleration has two separate new entries
Thrust has a manufacturer sub-one-second 0–60 mph claim. The recording reports 0.81 seconds during the unveiling. The conditions and exact production-trim mapping are incomplete, so those entries do not collapse into one “verified spec.”
Range has an explicit information gap
The old 620-mile claim is historical. No current trim range was verified in the checked official pages. An absent new figure is not proof of unchanged range, and it is not proof of a reduction either.
How we prevent parameter drift
Keep the original context
A value stays attached to its model, date, evidence status and conditions. When a source changes, we add a dated update rather than silently rewriting the earlier record.
A new lower number can mean a different question
The event’s over-230 mph discussion and the old over-250 mph target are different statements with incomplete conditions. We do not calculate a performance downgrade from those two thresholds.
No invented missing specs
Battery capacity, certified driving range, production weight and final prices remain unconfirmed in our current source set. There are no estimates disguised as complete rows.
Tesla Roadster questions, answered
Is the 1.9-second 0–60 mph claim new?
That figure is documented for the 2017 concept. The 2026 presentation reports a separate 0.81-second demo, while Tesla’s checked Thrust description says under one second.
Does the new Roadster still have a 620-mile range?
We have not verified a new trim-specific range or test cycle. The historical 620-mile concept claim is not a confirmed current specification.
