External upgrades on the car are available in either brushed aluminum, grass green or lavender. Each color corresponds to Abt's three new decór themes, namely Klecks, High-Voltage and Aloha. Parts available include a new front lip spoiler and side skirts, while rear updates include changes at the skirt, diffuser, and a new spoiler. The tuners also add on a new muffler with dual tailpipes as well as a new suspension. The company's Z Titan wheels may also be purchased as either 17- or 18-inchers.
Lastly and more importantly is the performance upgrade for the Abt A1. Engineers have tuned the 1.2-liter TFSI to deliver 115 hp while the output on the 1.4-liter TFSI is brought up to 150 hp from 122 hp. The 1.6-liter TDI engines are not left out, receiving an upgrade to either 110 or 125 hp.
