1998 F1 Regulations
Grooved Tires and Narrow Cars
The FIA's most aggressive attempt to peg back cornering speeds. Track width dropped from 2,000 mm to 1,800 mm, slick tires were replaced by grooved compounds (three grooves front, four rear), and front wing dimensions were restricted: all aimed at cutting grip. Brakes were restricted and the safety standards for the survival cell and side impacts were raised. The cars were slower at first, but the aerodynamicists were clawing speed back before the season was over.
Typical Engine
Configuration
V10
Capacity
3.0L
Aspiration
Naturally Aspirated
Power
~800 hp
What Changed
Car Width
2,000 mm
1,800 mm (−200 mm)
Tires
Full slick tires
Grooved tires (3 grooves front, 4 rear)
Brakes
Thicker discs (34 mm), beryllium allowed
Discs cut to 28 mm, beryllium banned, one caliper per wheel
Downforce
Higher overall downforce
Up to ~20% less (estimate, from the narrower track)
Side Impact Safety
Previous side-impact test
Test energy up nearly 100%, side headrests extended
Impact on Racing
- McLaren's MP4/13 (designed by Newey) was dominant out of the box, and Hakkinen took his first World Championship
- Within a couple of seasons the aero departments had clawed back much of the lost downforce through upper-body development
- Narrower cars changed overtaking geometry: the racing line tightened and side-by-side running required less road
- Grooved tires gave less consistent grip, particularly in mixed conditions, making wet/dry crossover sessions chaotic
- The pattern of 'FIA cuts speed, teams find it again within 18 months' became a defining dynamic of this period

How did the 1998 regulations affect racing?
McLaren's MP4/13 (designed by Newey) was dominant out of the box, and Hakkinen took his first World Championship. Within a couple of seasons the aero departments had clawed back much of the lost downforce through upper-body development. Narrower cars changed overtaking geometry: the racing line tightened and side-by-side running required less road.
What engines did F1 cars use under the 1998 rules?
V10, 3.0L, Naturally Aspirated, around ~800 hp. Notable engines: Mercedes FO 110G, Ferrari 047, Renault RS18, Ford Cosworth Zetec-R V10.
