recovery of about $28, with currency gains of $5 from settlement of transactions at the pre-devaluation rate providing  additional recovery. Program roll-offs reduced EBITDA by $13. Partially offsetting these adverse ef fects were $20 of material  cost savings and $7 of EBITDA benefit associated with higher sales volume on continuing programs. Pricing and material  recovery actions largely covered commodity and inflation-related cost increases. Reduced sales from currency ef fects in our Commercial Vehicle segment were due primarily to a weaker Brazilian real.  After adjusting for the ef fects of currency , 2013 sales in our Commercial Vehicle segment were down about 3% from 2012.  Lower Class 8 truck production in North America of 12% was the primary driver of the currency-adjusted sales reduction,  partially offset by growth in medium/heavy truck production of about 28% in South  America. Commercial Vehicle segment EBITDA in 2013 of $194 was $5 lower than in 2012, with EBITDA margin of 10.4% for  2013 being slightly better than the margin of 10.2% in 2012. Lower sales volumes reduced EBITDA by about $9. Material cost  savings of $23 was partially of fset by lower material recoveries from customers of $9 and an increase in operating costs of $12,  due in part to costs associated with the wind down of our foundry operation in  Argentina. Sales, net of currency effects, in our Off-Highway segment were down about 14% from 2012. Sales in 2012 included $32  related to a leisure and all-terrain business that was divested in 2012 and about $50 that was in-sourced in 2013 by one of our  customers. The remaining reduction was due principally to lower original equipment and aftermarket mining demand. Off-Highway segment EBITDA of $163 was $26 lower than in 2012, resulting in EBITDA  margins of 12.3% in 2013  compared to 12.5% in 2012. Lower overall sales volume which reduced EBITDA  by $54 was partially offset by material cost  savings of about $18, a reduction in warranty cost of $6 and pricing actions of $5. Power Technologies primarily serves the light vehicle market, but also sells product to the medium/heavy truck and of f- highway markets. Sales in 2013, net of currency ef fects, were up 3% reflecting stronger global light engine production demand. 28 Sales Segment EBITDA Segment EBITDA Margin 2012 $ 1,012 $ 137 13.5% Volume and mix 30 9 Performance (4) 6 Currency effects (8) (2) 2013 $ 1,030 $ 150 14.6% Sales Segment EBITDA Segment EBITDA Margin 2012 $ 1,509 $ 189 12.5% Volume and mix (179) (54) Divestiture (32) Performance 5 27 Currency effects 27 1 2013 $ 1,330 $ 163 12.3% Off-Highway Power Technologies Commercial Vehicle Sales Segment EBITDA Segment EBITDA Margin 2012 $ 1,960 $ 199 10.2% Volume and mix (40) (9) Performance (9) 2 Currency effects (51) 2 2013 $ 1,860 $ 194 10.4%
