BROTHERS Guillermo Echeverria and Iker Echeverria, sons of race driver Guillermo Senior, have formed their own Mexico City- and Detroit-based design agency, ETXE, which penned the Vuhl 05—a lightweight supercar for the road and the track in the vein of the BAC Mono, Ariel Atom and KTM X-Bow.
What the 05 packs is a monocoque that weighs in at a mere 78 kilograms, leading to a dry weight for the entire car of only 695 kilograms. The chassis comprises a three-section bonded tub constructed from aluminum extrusions and an aluminum honeycomb, which result in high torsional rigidity for optimum handling. Bolted directly to the passenger cell is a chrome-moly steel subframe housing the engine and rear suspension. A three-stage forward crash structure and double layer sidewalls provide protection for the occupants.
The standard body is made from RTM reinforced plastic, but carbon-fiber is an option. The 05’s aero features include a flat underbody, front and lateral splitters, rear diffuser and rear spoiler.
Powering the car is a Ford 2.0-liter turbo-charged EcoBoost engine that makes 285 horsepower and 420 Newton-meter of torque, leading to a power-to-weight ratio of 400 horsepower per ton—good for a naught-to-100kph sprint time of 3.7 seconds and a top speed of 245kph. Sending the power to the rear wheels is a six-speed manual gearbox. Unequal length double wishbones front and rear suspend the car while braking duties are handled by four-pot calipers all around. OZ alloys shod with Michelins sized 205/45 R17 in front and 235/45 R18 in the rear put the oomph to the tarmac.
No doubt, the brothers Echeverria know their go-fast stuff. Where they could use some help is in naming cars.
