Mexican carmaker VUHL has unveiled an enhanced version of its 05 road-legal lightweight supercar. Named the 05RR, this updated model lives up to the company’s name, with VUHL being an acronym for ‘Vehicles of Ultra-lightweight and High Performance’.
Indeed vehicle weight has been reduced by 65kg to a maximum dry weight of 660kg, and the engineering team reports that weight distribution has been “markedly” improved. A lightweight flywheel, lighter race clutch and full carbon wheels have reduced rotational inertia and boosted engine performance in the 05RR, with the 0-60mph taking a claimed 2.7 seconds, aided by increases in power and torque output of 115bhp and 100Nm respectively, with the power-to-weight ratio increased by 200bhp/tonne to a total of 600bhp/tonne.
Mechanically, a lower powertrain position has enabled the 05RR’s center of gravity to be lowered by 50mm which, combined with a sequential paddle shift gearbox, limited slip differential (LSD) and a track-focused suspension and steering system, increases grip. VUHL also offers the option of a bespoke track-specific suspension setup and slick tires for the 05RR.
The exterior looks a little more aggressive the 05, which is not just a styling decision, as the large single-plane rear wing and carbon wheels add to the chassis’ overall performance, with the all-new high-downforce setup on the 05RR, combined with the shift in weight distribution of 4%, creating 1.8G of lateral acceleration.
Iker Echeverria, VUHL’s technical director, is pleased with the result. As he stated, “The VUHL 05RR is more exciting, more engaging and faster than ever before. We have been listening to feedback, doing some learning and quietly developing and evolving our offering for a number of years. The result is truly remarkable, a car that is devoid of restraint and an improvement in almost every area.”
